AbstractSmall pendant discs known as Scandinavian gold bracteates are visually impressive indicators of status and identity during the early medieval Migration Period (c. 450–550 CE). Much of the emphasis in bracteate studies has been on typological classification and iconographic interpretation of the pictures, along with decipherment of the inscriptions, yet the sensory impression made by bracteates has been neglected. For decades, archaeologists considered it futile to speculate on the experiential; however, recent research has begun to contend with the materiality of senses and emotions in the past. In this paper, I focus on the both sensory effect of experiencing the pendants and the emotional impact of the objects on those who wore and handled them. Since bracteates are often discovered in women’s graves and show evidence of wear on their suspension loops, it is assumed that these objects were actually used in life. A spotlight on agency turns the study of bracteates from an emphasis on typology, iconography, and runology to trace instead the agency and multisensory effects of these objects on people and the effects of people’s actions on these items. This allows an examination of how bracteates were entangled with the senses and emotions of those who made, wore, and gazed upon these small but important objects. I consider what it may have felt like to make, receive, wear, lose, or bequeath a bracteate – or to deposit it into a bog or a grave.

Women in lron Age Scandinavia were not passive homemakers. Instead they had considerable interest in and occasional influence over events outside the domestic sphere. Through a study of the gold bracteates - their function, runic inscriptions and iconography —the role of women will be investigated. Gold bracteates were not artefacts with exclusively male associations, but rather, they demonstrate the influence of women in political matters.

A coin hoard found by private metal detecting on 9th October 2012 on the cadastral territory of Bořanovice (Prague-East District) consisted of five bracteates of the Bohemian King Přemysl I Ottokar (1192–1193, 1197/1198–1230), 42 bracteates of Henry III the Illustrious, Margrave of Meissen (1221/1230–1288), and two pfennigs struck in the imperial mint of Eger during the reign of the Emperor Frederick II (1212/1220–1250). The hoard had been buried probably around 1230.

Abstract Around 1950, during the forestry works near Natternberg (local part of Deggendorf, Lower Bavaria), some 26 bracteates were found. Only in 2012, the grandson of the finder reported the hoard and passed it for documentation to the Staatliche Münzsammlung München. Later on, the coins were returned to the owner and then sold in the numismatic auction. The Bohemian part is represented by three large bracteates struck under King Ottokar I of Bohemia (1192–1193, 1197–1230) during the last decade of his rule (cat. nos. 1–3). The Meissen coins are represented by 23 large bracteates struck (cat. nos. 4–26) under Margrave Henry III the Illustrious (1221/1230–1288) during the first decade of his rule. The hoard was buried in Natternberg very likely sometimes around 1230. Appearance of the Bohemian and Meissen bracteates is quite rare in Lower Bavaria, the twosided pfennigs from Regensburg and Passau circulated there predominantly. But it is still possible to think about their transfer from Bohemia, most likely from the Sušice surroundings, which was, as a possession of the Bavarian Counts of Bogen at that time (from the 12th century until 1242), connected through Gunther’s path with Deggendorf surroundings. The hoard could represent a separated part of a larger cash of a tradesman, which was possibly intended for hiding because of the forced exchange in the local markets.

Abstract The inscriptions on two late Roman Iron Age coins conserved in the Ossolineum in Wrocław appear to record an early Gothic noun and name respectively. One, an imitation of an aureus of Severus Alexander, bears a runic text that seems best to be taken as [h]rustis ›adornment‹. The other, an aureus of Postumus, appears to feature a name Gunþeis or Gutteis scratched into it recorded in Greek letters. Both of the coins feature holes bored in them, indicating that they were formerly worn as pendants, much like the later Migration Age bracteates.

This paper investigates the fact that many Early Iron Age wetland sacrifices were deliberately placed in liminal zones. The sacrifice of horses as well as the manipulation of their heads, hoofs and tails turned them into liminal creatures. In this way they imitated the liminal creature, in particular the Midgard Serpent that bites its tail in the ocean surrounding the world, and the horses also became guards against dangerous powers from outside Midgardr. The attention to tongues can also be seen on the bracteates that may have served as amulets, reminding their users ofthe creatures guarding the borderlands.

AbstractAccording to the latest collation of theNabonidus Chronicle, a reference is made to Cyrus the Great wearing an ‘Elamite’ garment during the investiture ceremony of Cambyses. This study examines the likely characteristics of this garment in the light of a recent study of seventh- and sixth-centurybcElamite elite garments. Within this context it is suggested that theChroniclemay have done no more than state the obvious. In 538bc, Cyrus went to Babylon clad in (traditional) Elamite (style) attire. This ceremonial garment is to be identified with a fine (perhaps cotton-made) fringed robe decorated with bands, including golden bracteates.

Full textAbstract:
Knowledge and initiationAn iconographic interpretation of selected B-bracteatesMany theories concerning the identification of the motifs on the bracteates have been put forward through the years. A certain category of pictorial elements consisting of abstract and geometrical forms are often treated as unimportant with respect to the constitution of the content – as opposed to the figural elements, which have played the main part in the search for the identification of the motif – even though they are highly characteristic of the form of the bracteates. An authoritative statement of this view is found in Mackeprang 1952, where these abstract signs are dismissed as mostly ornamental in function and expressions of horror vacui. In this article, I will try to establish a more central role for these abstract signs in the interpretation process and to show that these elements do in fact make sense; that they are important to the content of the motif, and that their semantic meaning does not elude us completely. To demonstrate this, I take as my example four closely related bracteate motifs of the so called B-type, which depict bearded and apparently naked men with the arms posed in a dynamic gesture and with prominent extended thumbs as its figurative qualities, along with prominent abstract symbols in the periphery of the motif, foremost of which are circular shapes characteristically grouped in threes, as its abstract pictorial elements (Fig.2). These I term extra somatic elements, i.e. objects outside the body of the central figure. Runic inscriptions are also found on the discs. It is difficult to read a coherent meaning from the runic inscriptions, with the exception of one specimen: “I, Glistening Eye, consecrate the runes.” The other texts are more oblique, with distortions of common formulaic words of which ōþal, “land right by inheritance,” is most significant for the following interpretation.As an interpretive framework, I suggest the theory that these motifs can be regarded as based on the religious concept of the gaining of supernatural knowledge in an initiation scenario. This suggestion is afforded by comparison with written sources. An important step in the identification of the content has been made by Hilda Ellis Davidson (1989) when she identified the raised hand with the prominent thumb as a gesture signifying the gaining of supernatural knowledge. In a narrative context, this motif is connected to the acquisition of a wondrous food or elixir, which bestows supernatural insight on the subject.A short introduction to the concept of initiations is given, summarizing the research of Arnold van Gennep, Mircea Eliade and Victor Turner. The fact that the scenario of the initiation is tripartite (Fig.1) is stressed: The scenes move from a state in which the ignorant subject is separated from ordinary life to a second state where extraordinary things can happen and where the subjects encounters “The Sacred” or “Wholly Other” and is thereby transformed as he receives numinous knowledge, which leads to the third and final state, in which he has reached a spiritual and socially higher state of being. Symbolism revolving around death and rebirth is a characteristic of this transformation of the subject. The middle state, the liminal phase, is central to the concept, because the subject is seen here as caught between absolute extremes, “betwixt and between” in the words of Turner. Notable research on the subject concerning the old Scandinavian religion is also summarized. Jere Fleck has identified a “knowledge criterion” in the succession to the Germanic kingship, in which the acquisition of numinous knowledge by the pretender to the crown is essential to his success. The most comprehensive recent research on the subject is by Jens Peter Schjødt, who provides a working model of what to expect from the structure and symbolism of an initiation in a pre-Christian Scandinavian context. It appears that the interplay between This and The Other World is essential, in that the numinous knowledge is always envisioned as an object to be extracted from its guardian in The Other World (which is most often The Underworld), generally characterized as feminine in semantic content, whereas the subject is always male. I begin the interpretation by rejecting the view that the rather large circular objects on the torso are supposed to signify female breasts, and that this in combination with the beard makes the figure an androgynous being. A version of this theory goes on to identify the figure with a sorcerer similar to the shamans of Siberia, where “ritual perversion” was practised to enhance the powers of the shaman (Motz 1994). This opinion is connected to an interpretation of the seiðr and ergi complex (specific Norse concepts of sorcery and defamation respectively) as belonging to the shamanism complex, which is debatable. Another understanding can be reached if we allow the breasts to be simply nipples on an otherwise masculine naked body. Significant parallels are found between this motif and the description by the Arab diplomat Ibn Fadlan of rites in connection with the burial of a chief or royal person among the Rus (Scandinavians) on the shores of the Volga River in A.D. 922. He describes how the closest relative to the sovereign (his heir) ignites the pyre by walking backwards naked with his one arm raised in front of him and his other arm on his back. This rite has been interpreted as a rite of succession. The nakedness and the gesture are homologous to the bracteate motif in question. I suggest that this rite is not an invention of The Viking Age by comparison with a juridical rite, the Chrenecruda, from the Frankish Law of Lex Salica, written in the late reign of Clovis, i.e. around 500 A.D. and contemporary with the bracteates. This law describes how the offender who can not pay the wergild must gather dirt from the four corners of his house, take up a position on the threshold of the door with his back to his nearest relative, who is standing outside the house, and throw the dirt on him over his own shoulder, whereby the obligation of paying wergild falls on the relative. The two rites can be seen as inversions of each other, the one a rite upgrading the social position of the subject, the other a rite of degradation. At this point, the concept of ōþal enters the picture. Whereas the offender in the Chrenecruda loses his ōþal, the successor to the crown gains his. I suggest that the ōþal in the Rus case implies achievement of the “knowledge criterion”, which would make the function of the rite a transferral from The other World – i.e. the funeral pyre as a manifestation of the Kingdom of Death – of numinous knowledge to the new sovereign. As regards the motif on the bracteates, it can be demonstrated that numinous knowledge in the pre-Christian tradition is characteristically represented as a group of three objects. I further suggest that the reason for representing the groups of three extra somatic objects three times, in three different places, is connected to the conception that the numinous object must go through a cyclic journey through the cosmos in order to be refined and become fruitful. This is reflected in the myth of the acquisition of the mead of poetry, where wisdom in the embodied form of the god Kvasir is manufactured into mead contained in three vessels and placed in The other World, before being brought back to This World for use again by Odin. This conception is analogous to the structure of an initiation rite, and the cosmological implications are reflected in the microcosmic body, where oppositions such as front-back and head-abdomen are active structuring metaphors. In this way the gesture, nakedness and the different positions of the extra somatic objects on the motif (that is, their positions according to the different parts of the body of the central figure) reflect the progression of an initiation. It is not a coincidence that the comprehensible runic text speaks of the consecration of esoteric knowledge (runes) by a first person speaker (Glistening Eye), which can be seen as a speech act marking the critical point in a rite of initiation, namely the acquisition of numinous knowledge.By insisting on the importance of the extra somatic symbols in the motif and identifying them as objects of numinous knowledge, combined with the notion of the body as a classificatory system seen in the context of pre-Christian cosmology, a new understanding of this motif has been reached where the motif can be interpreted as a rite of initiation or succession of a sacral chief. This is an alternative to the common opinion that shamanism is the key concept to unlocking the motif. The common occurrence of the gesture with the thumb and the extra somatic symbols on the bracteates as a whole suggest that the perspective put forward here might possibly have a wider application.

Their uniqueness stems from their decoration, which was made using a stamp technique (ceramics decorated with a stamp decoration are called StempelverzierteKeramik), probably with a bracteate type coin. In order to be able to present these artefacts as fully as possible, it is also necessary to present the context of their discovery, the history of the site as well as an attempt at interpretation.

This research was conducted to determine the effect of the combination of planting media on the growth of Mucuna bracteata by applying vermicompost. The research had been carried out in the practical garden of the Polytechnic of Lembaga Pendidikan Perkebunan, Wedomartani, Yogyakarta for 2 months from September to October 2019. The research method used a non-factorial randomized block design (RBD) with five treatments. The treatment carried out was a combination of planting media, between soil and vermicompost, namely P0 (100% soil), P1 (80% soil and 20% vermicompost), P2 (60% soil and 40% vermicompost), P3 (40% soil and 60% vermicompost) and P4 (20% soil and 80% vermicompost). The parameters observed in the study were plant height, number of leaves, and stem diameter. The results showed that the growth of Mucuna bracteate seedlings was influenced by the application of vermicompost. The highest plant height and stem diameter in Mucuna bracteate seedlings were obtained in P3 treatment (40% soil and 60% vermicompost), while the highest number of leaves was obtained from P4 treatment (20% soil and 80% vermicompost). Vermicompost can increase soil support for the growth of Mucuna bracteate seedlings so the growth of Mucuna bracteate increases.

The article considers the economic and political use of small lead seals (tag seals) to validate different kinds of social relations in early medieval Poland and Rus’. Originated in Antiquity, the practice of sealing peaked in Byzantium from where it spread to Early Rus’. This is reflected, for example, in the use in late 11th-late 14th centuries of small lead seals referred to as the “Drohiczyn type”. In this paper I put forward an opinion that not all the early medieval small lead seals should be attributed to “coinless economy”. A study of the corpus of small lead seals from Drohiczyn and Czermno, and finds from Mazovia, has identified a group with iconography identical to the Polish Hohlpfennig, suggesting they were commercial-customs small lead seals used by the Piast dynasty, contemporary with the bracteates introduced in the first half/mid-13th-early 14th centuries. The extraordinary number of small lead seals found in Drohiczyn possibly reflects the outstanding position of the town in the Eastern and Central European relationships as well as a short-term relocation of trade routes leading north, caused by the military conflicts of the 1240-1280s in the upper course of the Western Bug. The practice of sealing could have been introduced by Conrad of Mazovia to Poland from Early Rus’. Subsequently, the small Polish lead seals might have contributed to the emergence of lead cloth seals in Western Europe as part of a cultural transfer.

ABSTRACTMucuna bracteata DC. is a species of legume cover crop that rapidly grow into the palm circles and climb and wind around the main trees and reduce the effectiveness and efficiency of plantation maintenance. These problems should be able to be controlled by slowing down the growth rate of M. bracteataby applied retardant such as paclobutrazol. This research was aimed to determine the level of concentration of the retardant and the growth suppression rate on M. bracteata. This research was conducted at the Teaching and Research Farm of Oil Palm Plantation of IPB, Singasari Village, District of Jonggol, Bogor Regency in February to May 2016. The application of paclobutrazol was done by spraying the retardant solution on the shoot of M. bracteata’s canopy. Paclobutrazol concentrations of 100 ppm and 200 ppm were treatments that significantly reduced rate of the growth of shoot and dry weight, compared to other treatments. The treatments of 100 ppm and 200 ppm, consequtively gave the suppression rate of 61.02% and 63.45 % and prolonged the rotation time of weeding, 141 and 156 days, compared to the control.Keyword : concentration, paclobutrazol, retardantABSTRACTMucuna bracteata DCadalah spesies kacang-kacangan penutup tanah yang sangat cepat bertumbuh memasuki piringan dan melilit tanaman utama dan mengurangi keefektifan dan efisiensi pemeliharaan.

With crosses between colchicine-induced tetraploid shashanbo (Vaccinium bracteatum section Bracteata) and tetraploid highbush blueberry ‘Spartan’ (Vaccinium corymbosum section Cyanococcus), intersectional hybrids were produced. The hybridity of these plants was confirmed based on DNA markers and morphological characteristics. The morphological characteristics, blooming date, and ripening period of the hybrids were intermediate between those of the parents. Ploidy analyses by flow cytometry and chromosome counting revealed that these hybrids were tetraploid. Four hybrids set fruit in the field and these two hybrids showed high pollen stainability. It was noteworthy that fruit of two hybrids had high soluble solids concentration compared with ‘Spartan’ and the fruit pulp of the hybrids was tinged with red as shashanbo. These hybrids could be useful in breeding new cultivars with high sugar content, abundant phytochemicals, extensive environmental adaptability as well as late flowering and fruit maturity.

Five taxa of Helichrysum Mill. and Brachycome Cass. were recently evaluated for greenhouse production and amenity use. Preliminary studies on the influence of photoperiod, temperature, and growth regulators were conducted for H. bracteatum Vent., (syn Bracteantha bracteata) `Sunray' and `Matilda Yellow', H. apiculatum D.C, (syn Chrysocephalum apiculatum) `Golden Buttons' and Brachycome iberidifolia Benth. `Jumbo Mauve' and `Mauve Delight'. All taxa of Helichrysum were quantitative LD plants, flowering slightly more rapidly under night-break (2200-0200 HR) and extended day incandescent lighting, compared with 9-h short-day treatment. No influence of photoperiod occurred with cultivars of Brachycome. Constant temperature of 12, 20, or 28 °C were provided and all taxa demonstrated a linear decrease in flowering time as temperatures increased. The growth index (average of height and two measurements of width) was also influenced by temperature. Paclobutrazol and daminozide were applied at different concentrations and frequencies. Paclobutrazol was more effective than daminozide in both genera, and daminozide was ineffective in Brachycome.

The analysed coins will be compared with finds obtained during excavations in other cities in Upper Silesia – Gliwice (germ. Gleiwitz) (the market square and St. George’s Church in Czechowice (germ. Schechowitz)) and Bytom (germ. Beuthen) (St. Margaret’s Hill) – and in the main centre in Lower Silesia, Wrocław (germ. Breslau) (Nowy Targ Square and St. Elizabeth’s Church). The study includes 76 coins acquired in the years 1979–2015 on 12 sites located within the borders of the city of Racibórz. This number includes the hoard of 17 Prague groschen of Wenceslas II, 56 single finds and three coin-like objects. In addition, two metal objects were included in the study which were discovered near the castle in the district of Racibórz – Ostróg. Both objects are difficult to identify, initially defined as a ring eye and a weight (monetary or merchant). The entire collection is dominated by Bohemian coins, including Prague groschen, parvus and white pennies. Silesian coins are the second largest group – three wide bracteates (unfortunately without provenance), a very rare Opava heller of Přemek I (1377–1433) and two groeschels of Ferdinand II (1617–1637). Moreover, two rare pennies of Sigismund III (1587–1632) struck in Poznań mint were found, which usually give way to pennies and ternarius struck in Łobżenica mint, which were not recorded in the collection from Racibórz. Considering all the coins in chronological terms, the dominant coins are late medieval ones – from the second half of the 13th century to the first half of the 15th century. The second concentration of Racibórz finds is from the 18th–20th century. A comparative analysis of coins discovered in Racibórz, Gliwice and Bytom and the hoard of Prague groschen from Błażejowice (germ. Blaschowitz) confirms the hypothesis of Borys Paszkiewicz that it was through Upper Silesia that Bohemian coins reached the territory of present day Poland. As a result, there is a significant number of small Bohemian coins in this area, with a smaller number to be found deeper within Poland.

Full textAbstract:
Background The chimeric leaves of Ananas comosus var. bracteatus are composed of normal green parts (Grs) and albino white parts (Whs). Although the underlying mechanism of albinism in A. comosus var. bracteatus leaves is not fully understood, it is likely associated with the chlorophyll (Chl) biosynthesis. In this biosynthetic process, porphobilinogen deaminase (PBGD) plays a crucial role by catalyzing the conversion of porphobilinogen (PBG) to uroporphyrinogen III (Urogen III). Therefore, its encoding gene AbhemC was investigated here in association with Chl biosynthesis and albinism in chimeric A. comosus var. bracteatus leaves. Methods The Chl content, main Chl biosynthesis precursor content, and main enzyme activity were determined and compared between the Whs and Grs of A. comosus var. bracteatus leaves. In addition, AbhemC was cloned and its transcriptional expression and prokaryotic protein expression were analyzed. Furthermore, RNAi-mediated silencing of AbhemC was produced and assessed in tobacco plants. Results The concentration of Chl a and Chl b in the Grs was significantly higher than that in the Whs, respectively. Additionally, the content of the Chl biosynthesis precursor Urogen III decreased significantly in the Whs compared with the Grs. Thus, the transition of PBG to Urogen III may be the first rate-limiting step leading to albinism in the chimeric leaves of A. comosus var. bracteatus. The gene AbhemC comprised 1,135 bp and was encoded into a protein with 371 amino acids; phylogenetically, AbhemC was most closely related to hemC of pineapple. Prokaryotic expression and in vitro enzyme activity analysis showed that the cloned mRNA sequence of AbhemC was successfully integrated and had PBGD activity. Compared with control plants, transgenic tobacco leaves with pFGC5941-AbhemC-RNAi vector were substantially less green with significantly reduced hemC expression and Chl content, as well as reduced PBGD enzyme activity and significantly decreased content of Chl biosynthesis precursors from Urogen III onwards. Our results suggest that the absence of hemC expression reduces the enzyme activity of PBGD, which blocks the transition of PBG to Urogen III, and in turn suppresses Chl synthesis leading to the pale-green leaf color. Therefore, we suggest that AbhemC plays an important role in Chl synthesis and may be an important factor in the albinism of A. comosus var. bracteatus leaves.

Full textAbstract:
Viburnum bracteatum Rehd. is a member of the “dentatum” complex represented by at least three types: V. bracteatum, V. dentatum L., and V. rafinesquianum Schult. V. bracteatum is an endangered species in Georgia and at the federal level is a candidate as an endangered species. Two populations were located in northwestern Georgia; however, there is some concern as to whether they are in fact V. bracteatum. To determine if it is possible to distinguish between the three Viburnum species, cellulose acetate electrophoresis to detect isozyme variation was done. Polymorphic enzymes resolved were alcohol dehydrogenase, malic dehydrogenase, glucose-6-phosphate dehydrogenase, malic enzyme, 6-phosphogluconate dehydrogenase, phosphoglucomutase, and phosphoglucose isomerase. Fresh bud tissue was used, and tissue samples were electrophoresed three times for each enzyme assayed. A review of 100 phylogeny trees created with Dollop analysis was done. V. rafinesquianum, the known sample of V. bracteatum, and the 12 samples of possible V. bracteatum were all equally parsimonious. V. dentatum was consistently an outgroup. In conclusion, isozyme variation can assist in Viburnum species distinction.

Di perkebunan karet, sejak sepuluh tahun terakhir ini dikembangkan kacangan penutup tanah (LCC) Mucuna bracteata. Dibandingkan dengan LCC konvensional, Mucuna bracteata mempunyai keunggulan antara lain : laju pertumbuhan cepat, produksi biomassa tinggi, tahan terhadap naungan, tidak disukai ternak, toleran terhadap serangan hama dan penyakit, dapat berkompetisi dengan gulma dan pengendali erosi tanah secara baikKendala yang dihadapi para pekebun dalam mengembangkan M. bracteata adalah terbatasnya ketersediaan benih karena harus diimport dan harga benih cukup mahal. Pertanyaan yang sering disampaikan oleh para pekebun adalah bagaimana teknik memperbanyak tanaman M. bracteata, sehingga memberikan keberhasilan hidup yang tinggi. Di dalam tulisan ini diuraikan secara lengkap pembiakan M. bracteata dengan cara stek batang, cara penyusuan serta dengan benih. Biaya untuk membuat satu bibit polibeg M. bracteata dengan ketiga cara tersebut diatas adalah hampir sebanding yakni Rp 574,- (dengan biji), Rp 582,- (dengan stek) dan Rp 533,- (melalui penyusuan). Dengan asumsi bahwa keberhasilan stek dan penyusuan adalah sama yaitu masing-masing 60%, maka jumlah tanaman polibeg yang dihasilkan dengan cara stek adalah mencapai 90.000 polibeg/ha sementara dengan cara penyusuan hanya 12.000 polibeg. Untuk penanaman baru, per hektar tanaman di lapangan dibutuhkan sebanyak 600 polibeg M. bracteata (termasuk bahan penyisip 10%). Dengan asumsi daya kecambah sekitar 63%, maka satu kilogram benih M. bracteata dapat memenuhi 7 ha tanaman karet di lapangan.

Full textAbstract:
In the Yucatan Peninsula, the ponerine ant Neoponera villosa nests almost exclusively in tank bromeliads, Aechmea bracteata. In this study, we aimed to determine the factors influencing nest site selection during nest relocation which is regularly promoted by hurricanes in this area. Using ants with and without previous experience of Ae. bracteata, we tested their preference for refuges consisting of Ae. bracteata leaves over two other bromeliads, Ae. bromeliifolia and Ananas comosus. We further evaluated bromeliad-associated traits that could influence nest site selection (form and size). Workers with and without previous contact with Ae. bracteata significantly preferred this species over others, suggesting the existence of an innate attraction to this bromeliad. However, preference was not influenced by previous contact with Ae. bracteata. Workers easily discriminated between shelters of Ae. bracteata and A. comosus, but not those of the closely related Ae. bromeliifolia. In marked contrast, ants discriminated between similar sized Ae. bracteata and Ae. bromeliifolia plants, suggesting that chemical cues and plant structure play an important role. Size was also significant as they selected the largest plant when provided two dissimilar Ae. bracteata plants. Nest site selection by N. villosa workers seems to depend on innate preferences but familiarization with plant stimuli is not excluded.

Full textAbstract:
Light environment and crown architecture were investigated in two closely related species (deciduous Vaccinium hirtum and evergreen Vaccinium bracteatum) in a young and an old secondary forest. Light environment was determined by photographic estimation of light above ramets (30500 cm tall). Crown architecture was examined to determine the effects of ramet age and light level on several architectural traits. In the young secondary forest, both species were mainly found in large gaps. In the old secondary forest, V. bracteatum persisted in deep shade, whereas V. hirtum was concentrated in small gaps. Vaccinium hirtum had narrower crowns and thinner stems than V. bracteatum, indicating lower structural costs in V. hirtum. Older ramets had greater total shoot extension (only V. bracteatum) and shorter length of the current-year shoots (markedly so in V. hirtum) than younger ramets. In higher light levels, V. bracteatum had greater aboveground growth and higher leaf area indices, whereas V. hirtum had only greater flowering intensity. Architectural traits were highly correlated with ramet age in V. hirtum, whereas these were mainly affected by light in V. bracteatum, indicating higher architectural plasticity in the latter species. The differences in architecture and its plasticity can be relevant for the segregation of light habitats between the species.Key words: light environment, crown architecture, leaf display, morphological plasticity, current-year shoot.

The prominent antibacterial and quorum sensing (QS) inhibition activity of aromatic plants can be used as a novel intervention strategy for attenuating bacterial pathogenicity. In the present work, a total of 29 chemical components were identified in the essential oil (EO) of Melaleuca bracteata leaves by gas chromatography-mass spectrometry (GC-MS). The principal component was methyleugenol, followed by methyl trans-cinnamate, with relative contents of 90.46% and 4.25%, respectively. Meanwhile, the antibacterial activity and the QS inhibitory activity of M. bracteata EO were first evaluated here. Antibacterial activity assay and MIC detection against seven pathogens (Dickeya dadantii Onc5, Staphylococcus aureus ATCC25933, Pseudomonas spp., Escherichia coli ATCC25922, Serratia marcescens MG1, Pseudomonas aeruginosa PAO1 and Chromobacterium violaceum ATCC31532) demonstrated that S. aureus ATCC25933 and S. marcescens MG1 had the higher sensitivity to M. bracteata EO, while P. aeruginosa PAO1 displayed the strongest resistance to M. bracteata EO. An anti-QS (anti-quorum sensing) assay revealed that at sub-minimal inhibitory concentrations (sub-MICs), M. bracteata EO strongly interfered with the phenotype, including violacein production, biofilm biomass, and swarming motility, as well as N-hexanoyl-L-homoserine lactone (C6-HSL) production (i.e., a signaling molecule in C. violaceum ATCC31532) of C. violaceum. Detection of C6-HSL indicated that M. bracteata EO was capable of not only inhibiting C6-HSL production in C. violaceum, but also degrading the C6-HSL. Importantly, changes of exogenous C6-HSL production in C. violaceum CV026 revealed a possible interaction between M. bracteata EO and a regulatory protein (cviR). Additionally, quantitative real-time polymerase chain reaction (RT-qPCR) analysis demonstrated that the expression of QS-related genes (cviI, cviR, vioABCDE, hmsNR, lasA-B, pilE1, pilE3, and hcnB) was significantly suppressed. Conclusively, these results indicated that M. bracteata EO can act as a potential antibacterial agent and QS inhibitor (QSI) against pathogens, preventing and controlling bacterial contamination.

Asthma is a chronic lung inflammation which affects many people. As current therapies for asthma mainly rely on administration of glucocorticoids and have many side effects, new therapy is needed. In this study, we investigated Nepeta bracteata Benth., a traditional Uygur Herb, for its therapeutics effect in OVA induced asthmatic mice model. Treatment of OVA sensitized asthma mice with extract from Nepeta bracteata Benth. demonstrated improved lung pathology, as well as reduced infiltration of eosinophil and neutrophil. Nepeta bracteata Benth. extract also contributed to the rebalance of Th17/Treg cell via decreasing the Th17 cell and increasing the Treg, which was corresponding with the inhibited Th17 cytokine response and increased IL-10 level. Moreover, the reduced TGF-β level and Smad2/3 protein level also suggested that Nepeta bracteata Benth. extract could inhibit TGF-β mediated airway remodelling as well. Taken together, these data suggested that Nepeta bracteata Benth. may be a novel candidate for future antiasthma drug development.

Full textAbstract:
Helichrysum bracteatum, also known as strawflower, is commonly grown for the production of dried flowers and, more recently, as a potted plant. This latter cultivation system is becoming increasingly important on the Liguria Coast in northern Italy. During the spring of 2002, severe oubreaks of a previously unknown disease were observed in commercial farms in the area of Albenga (northern Italy) on several cultivars of H. bracteatum. Leaves of infected plants appeared curled and blistered; the infected portions of leaves turned chlorotic. On the lower leaf surface of chlorotic areas, a dense, whitish growth was evident. Infected leaves eventually wilted without dropping. Basal leaves with poor air circulation were the most severely affected. Certain cultivars of H. bracteatum (such as ‘Florabella Pink’) were most seriously affected, while others (‘Florabella Gold’ and ‘Florabella White’) had less disease. Microscopic observations revealed sporangiophores emerging from the stomata that were dichotomically branched, ending with 4 to 7 sterigmata. The sporangia were globose and measured 15.5 to 16.8 μm in diameter. The pathogen was identified as Bremia lactucae based on the morphological characteristics. Pathogenicity was confirmed by inoculating healthy H. bracteatum (100-day-old ‘Florabella Gold’) as well as Lactuca sativa (25-day-old ‘Salad bowl’) plants with a sporangial suspension (1 × 105 sporangia/ml). Five plants of H. bracteatum and 10 of lettuce were used as replicates. Noninoculated plants served as controls. Inoculated and uninoculated plants were maintained in a growth chamber at 20°C and 90 to 95% relative humidity. After 7 to 10 days, typical symptoms of downy mildew developed on H. bracteatum and lettuce plants artificially inoculated. Bremia lactucae was observed on infected leaves. Uninoculated plants did not show symptoms. To our knowledge, this is the first report of Bremia lactucae on H. bracteatum in Italy. B lactucae was previously reported as the causal agent of downy mildew on H. bracteatum in several countries including the United Kingdom (3), the United States (1), and Egypt (2). References: (1) S.

Full textAbstract:
Lampsilis bracteata (Gould), the Texas Fatmucket, is a regional endemic species in the central Texas biogeographic province which is a candidate to be listed as threatened or endangered under the Endangered Species Act of 1973. Lampsilis bracteata is morphologically similar to the common species L. hydiana (Lea). Here, we examine the molecular taxonomic identification of L. bracteata, and compare its historical range with its current geographic distribution. Tests of genetic affinities based on two mitochondrial genes typically used for DNA barcoding (cytochrome oxidase subunit 1, COI and NADH dehydrogenase subunit 1, ND1) support recognition of L. bracteata as a full species. An unexpected spin-off result was that ND1 sequences of L. satura (Lea), a threatened species in Texas, formed a highly supported cluster within putative L. cardium Rafinesque. As an endemic species, the distribution of L. bracteata has been historically restricted; however, poor land and water management practices have further reduced its distribution from eighteen to just eight streams in the Colorado River drainage and to one stream in the Guadalupe River drainage. For L. bracteata, as for many other imperiled freshwater mussel species, effective conservation measures rely on correct species identification, definition of its geographic range and assessment of its changes in the recent past.

The present work was carried out to assess the Onosma bracteatum anxiolytic and antidepressant properties. Swiss albino mice (male) were fed orally with hydroalcoholic extract at different doses 50, 100, and 200 mg 1 hour prior to test with the standard diazepam and fluoxetine. Anxiolytic and antidepressant activities were evaluated by using open field, elevated plus maze, force swimming, and tail suspension test. Results of open field test showed an increase in number of line crossing as well as number of rearing in dosage-dependent design. Although results of elevated plus maze test evidently showed antianxiety effect of O bracteatum by increasing the time spent in open arms along with decreasing the time spent in closed arms in dosage-dependent way. For the evaluation of antidepressant effect, O bracteatum diminished the immobility time and expanded mobility time in forced swim model in dosage-dependent way. Likewise, O bracteatum expanded time span of mobility along with diminished immobility time in tail suspension method in dosage-dependent way. Outcome demonstrated that plant at the dose of 200 mg/kg body weight showed significant potential which was similar to that standard diazepam and fluoxetine. Hence, O bracteatum may be used as potent natural psychotherapeutic agent against the mental disorders.

An independent article (Xiong et al. Sci. Rep. 8: 1947; 2018) reported var. bracteatus MIRNAs but not MIR828, a negative regulator of anthocyanin and polyphenolics biosynthesis by targeting MYB transcription factors associated with UV light- and sugar-signaling in dicots. MIR828 has been reported in gymnosperms, Amborella (sister to flowering plants), and basal monocot orders Liliales, Asparagales, Zingiberales, Arecales, but not in the Poales, a sister order comprising grasses and ~3,000 species of bromeliads including pineapple. Here I show MIR828 exists in pineapple and directs post-transcriptional gene silencing of mRNAs encoding MYB family members with inferred function to regulate the conspicuous red fruit trait in var. bracteatus.

Chen et al. (Nature Genet. 51: 1549–1558; Oct. 2019) sequenced Ananas comosus var. bracteatus accession CB5, cultivated for its bright pink-to-red colored fruit, and yellow-fleshed A. comosus accession F153, reporting an improved F153 reference assembly while annotating MICRORNA (MIRNA) loci and gene family expressions relevant to lignin and anthocyanin biosynthesis. An independent article (Xiong et al. Sci. Rep. 8: 1947; 2018) reported var. bracteatus MIRNAs but not MIR828, a negative regulator of anthocyanin and polyphenolics biosynthesis by targeting MYB transcription factors associated with UV light- and sugar-signaling in dicots. MIR828 has been reported in gymnosperms, Amborella (sister to flowering plants), and basal monocot orders Liliales, Asparagales, Zingiberales, Arecales, but not in the Poales, a sister order comprising grasses and ~3,000 species of bromeliads including pineapple. Here I show MIR828 exists in pineapple and directs post-transcriptional gene silencing of mRNAs encoding MYB family members with inferred function to regulate the conspicuous red fruit trait in var. bracteatus. MIR828 plesiomorphy (an ancient basal trait) may shed light on monocot apomorphic fruit development, postulated for 21 monocot families with fleshy fruits as due to homoplasy/convergence driven by tropical climate and/or enticements to vertebrate endozoic seed dispersers.

Full textAbstract:
The R2R3-MYB proteins comprise the largest class of MYB transcription factors, which play an essential role in regulating anthocyanin synthesis in various plant species. Ananas comosus var. bracteatus is an important colorful anthocyanins-rich garden plant. The spatio-temporal accumulation of anthocyanins in chimeric leaves, bracts, flowers, and peels makes it an important plant with a long ornamental period and highly improves its commercial value. We conducted a comprehensive bioinformatic analysis of the R2R3-MYB gene family based on genome data from A. comosus var. bracteatus. Phylogenetic analysis, gene structure and motif analysis, gene duplication, collinearity, and promoter analysis were used to analyze the characteristics of this gene family. In this work, a total of 99 R2R3-MYB genes were identified and classified into 33 subfamilies according to phylogenetic analysis, and most of them were localized in the nucleus. We found these genes were mapped to 25 chromosomes. Gene structure and protein motifs were conserved among AbR2R3-MYB genes, especially within the same subfamily. Collinearity analysis revealed four pairs of tandem duplicated genes and 32 segmental duplicates in AbR2R3-MYB genes, indicating that segmental duplication contributed to the amplification of the AbR2R3-MYB gene family. A total of 273 ABRE responsiveness, 66 TCA elements, 97 CGTCA motifs, and TGACG motifs were the main cis elements in the promoter region under response to ABA, SA, and MEJA. These results revealed the potential function of AbR2R3-MYB genes in response to hormone stress. Ten R2R3-MYBs were found to have high homology to MYB proteins reported to be involved in anthocyanin biosynthesis from other plants. RT-qPCR results revealed the 10 AbR2R3-MYB genes showed tissue-specific expression patterns, six of them expressed the highest in the flower, two genes in the bract, and two genes in the leaf. These results suggested that these genes may be the candidates that regulate anthocyanin biosynthesis of A. comosus var. bracteatus in the flower, leaf, and bract, respectively. In addition, the expressions of these 10 AbR2R3-MYB genes were differentially induced by ABA, MEJA, and SA, implying that these genes may play crucial roles in hormone-induced anthocyanin biosynthesis. Our study provided a comprehensive and systematic analysis of AbR2R3-MYB genes and identified the AbR2R3-MYB genes regulating the spatial-temporal anthocyanin biosynthesis in A. comosus var. bracteatus, which would be valuable for further study on the anthocyanin regulation mechanism of A. comosus var. bracteatus.

Full textAbstract:
Cavendishia bracteata and Thibaudia floribunda (Ericaceae) are wild fruit shrubs native to the Andes region. This study aimed to characterize the rooting potential of basal and apical cuttings using naphthalene acetic acid (NAA) in different concentrations (0, 200, 500, or 1,000 mg L-1). In C. bracteata, the cutting position on the branch affected its sprouting and rooting, with apical cuttings presenting the best performance with auxin application. The rooting of cuttings was more successful in C. bracteata than in T. floribunda. NAA applications between 200 to 500 mg L-1 were more suitable for the propagation of C. bracteata due to the higher percentages of rooting and shoot production. For propagation of T. floribunda, the use of apical cuttings without the application of auxins is recommended. Adventitious roots in cuttings of both species were originated from parenchyma cells of the stem.

Full textAbstract:
The taxonomic status of Garcinia bracteata (Clusiaceae), a species endemic to China, has been questionable because its taxonomic traits are indistinct from Garcinia anomala and Garcinia propinqua. According to field investigations, careful examination of herbarium specimens, and statistical analysis, we assert that the traits previously used for distinguishing between G. bracteata, G. anomala and G. propinqua are unreliable for distinguishing these species. Therefore, G. bracteata and G. propinqua are being treated as synonyms of G. anomala. G. anomala is the earliest named species and thus has nomenclatural priority.
