Resumen

Background Rosenbergiella nectarea strain 8N4T, the type species of the genus Rosenbergiella, was isolated from Amygdalus communis (almond) floral nectar. Other strains of this species were isolated from the floral nectar of Citrus paradisi (grapefruit), Nicotiana glauca (tobacco tree) and from Asphodelus aestivus. R. nectarea strain 8N4T is a Gram-negative, oxidase-negative, facultatively anaerobic bacterium in the family Enterobacteriaceae. Results Here we describe features of this organism, together with its genome sequence and annotation. The DNA GC content is 47.38%, the assembly size is 3,294,717 bp, and the total number of genes are 3,346. The genome discloses the possible role that this species may play in the plant. The genome contains both virulence genes, like pectin lyase and hemolysin, that may harm plant cells and genes that are predicted to produce volatile compounds that may impact the visitation rates by nectar consumers, such as pollinators and nectar thieves. Conclusions The genome of R. nectarea strain 8N4T reveals a mutualistic interaction with the plant host and a possible effect on plant pollination and fitness.

Resumen

The paper presents the results of model calculations of impact craters ejecta thickness variations in the south polar region of the Moon from the south pole to 70° S for craters of Nectarian, Imbrian, Eratos thenian, and Copernican ages. This work does not consider pre-Nectarian craters since younger deposits often hide the boundaries of their ejecta. Housen, Sharpton and Fassett models were chosen to estimate the power. The first was used for craters larger than 45 km in diameter, the second for smaller craters (from 3 to 45 km), and the third for the Mare Orientale basin. During estimation, the mixing factor of ejecta with the underlying regolith (factor μ) was considered. As a result, maps of ejecta thicknesses were produced for the Moon’s south polar region. They provide an opportunity for quantitative estimation of the various aged impact events’ contribution to the formation of polar regolith and, accordingly, to determine the dominant source (sources) of material in a particular area, not least in the proposed landing sites.

Resumen

Gram-negative, rod-shaped, oxidase-negative, facultatively anaerobic, yellow–orange-pigmented and motile bacterial strains, designated 8N4T, 9N2 and 10N3, were isolated from flower nectar of Amygdalus communis (almond) and Citrus paradisi (grapefruit). The 16S rRNA gene sequences of the strains shared highest sequence similarity of 97.0 % with that of Phaseolibacter flectens ATCC 12775T and lower similarity with sequences from other type strains of genera of the Enterobacteriaceae . A polyphasic approach that included determination of phenotypic properties and phylogenetic analysis based on 16S rRNA, gyrB, rpoB and atpD gene sequences supported the classification of strains 8N4T, 9N2 and 10N3 within a novel species in a novel genus in the family Enterobacteriaceae . Strain 8N4T, and the reference strains of the novel species, grew at 4–35 °C (optimum, 28–30 °C), with 0–5.0 % NaCl (optimum, 3 % NaCl) and with 0–60 % sucrose (optimum, 10–25 % sucrose). Their major cellular fatty acids were C16 : 0, C17 : 0 cyclo, C18 : 1ω7c and summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH). The DNA G+C content of strain 8N4T was 46.8 mol%. On the basis of phenotypic properties and phylogenetic distinctiveness, the floral nectar isolates are classified within a novel species in a new genus in the family Enterobacteriaceae , for which the name Rosenbergiella nectarea gen. nov., sp. nov. is proposed. The type strain of Rosenbergiella nectarea is 8N4T ( = LMG 26121T = DSM 24150T).

Resumen

Context. The cryptomare in the Balmer-Kapteyn region is the oldest one on the Moon. Determining the extent and formation of this feature can deepen our understanding of early mare volcanism and help establish temporal and spatial constraints on lunar thermal and volcanic history. Aims. This paper focuses on the identification of lunar cryptomaria and figuring out their formation processes. Methods. We used the Global WAC digital terrain model to analyze the terrain. We built a mathematical model using support vector machines and input Kaguya Multiband Imager data to estimate oxide concentrations in the Balmer-Kapteyn region. We used the Chandrayaan-1 Moon Mineralogy Mapper (M3) to analyze the minerals. We improved the cryptomare identification model to increase the accuracy of basalt identification in the cryptomare region. Finally, we used three methods to estimate the ejecta thickness of the target basin to the Balmer-Kapteyn region. Results. New Al2O3, CaO, FeO, MgO, and TiO2 maps were generated using the Kaguya Multiband Imager and a novel machine-learning model. As a result, the extent of the cryptomare in the Balmer-Kapteyn region was redefined and the formation process of the cryptomare in the Balmer-Kapteyn region was divided into five formation stages: Balmer basin formation, ejecta coverage from the Pre-Nectarian and Nectarian large impact basins, mare basalt filling, ejecta secondary coverage of high-albedo materials, and exposure of mare basalts. Conclusions. We found that the bottom of the Crater Vendelinus is likely to hide ancient mare basalt. Moreover, the high-aluminum mare basalt of the cryptomare is different from the composition of the exposed mare basalts in Mare Fecunditatis and Crater Vendelinus. The high-albedo material covering the cryptomare in the Balmer-Kapteyn region could have come from the Langrenus, Petavius, Humboldt, La Perouse, and Ansgarius Craters, along with some from the Orientale Basin impact event or potentially from the Imbrium Basin impact event.

Resumen

The section Paralias L. of the genus Euphorbia L. in the Circumboreal floristic region is revised using traditional taxonomic approach. The section is represented in the region by 16 species of 3 subsections. A special attention is paid to the E. nicaeensis All. aggregate. E. nicaeensis s. str. is regarded as almost strictly Mediterranean species differing from other members of the aggregate by nectarias with appendicules («horns»), even if very short. E. glareosa Pall. ex Bieb. is characterized by small (10–20 cm) and thin (1.5–2 mm) stems and usually 5 pseudoumbell rays. E. pannonica Host and E. stepposa Zoz ex Prokh. have stems (20)25–70 cm high, 2.5–4 mm diam. and psudoumbell of (5)7–16 rays. E. pannonica differs from E. stepposa by pilose fruits and/or presense of small «glareose» indumentum.

Resumen

Two new species of Syzygium Gaertn. from Sri Lanka, S. aureum Jayasinghe and S. hemachandrae Jayasinghe, are described. Syzygium aureumis distinguished from S.grande (Wight) Walp. in having a thick ring of nectarial glands near the rim of the hypanthium and in having subglobose fruits tinged with red at ripening. Syzygium hemachandrae differs from S. assimile Thwaites in having a longer petiole, an elliptic to ovate-elliptic lamina with fewer lateral veins, a cylindrical to subcylindrical peduncle at its basal parts and approximately quadrangular secondary axes. Syzygium aureum, which was previously misidentified as Syzygium firmum Thwaites (=S. grande), is restricted to the southwestern lowland rainforests, while S. hemachandrae is confined to the moist monsoon forests of the intermediate zone of eastern Sri Lanka. Both new species were found to be included amongst the syntypes of Syzygium assimile. We therefore designate a lectotype and recircumscribe Syzygium assimile.

Resumen

This paper identifies the theme of honey gathering in Charlotte Brontë's fiction and places it within the context of Romantic and early Victorian representations of the nectarium's role in insect-flower relationships. Brontë's novels often invert the conventional use of botany to represent female sexuality by representing men as flowers and endowing her protagonists with an ulterior form of entomological agency. These insects work to express Brontë's desire for greater economic and erotic mobility, but it is argued that this mobility is problematized by the self-absorbed nature of the masculine nectarium, a dulcet gland in flowers originally believed by botanists to ooze sugar to serve a plant's own needs. This is particularly evident in Brontë's industrial romance Shirley (1849), as the theme of honey gathering is pathologized to visualize a crisis in the plotting of Victorian femininity. This paper may be helpful to scholars interested in Brontë's fiction, representations of sexuality, botany, entomology, ecology, and early Victorian pest discourse.

Resumen

Abstract At c. 820 km in diameter, the Smythii impact basin is one of the large lunar basins (>200 km diameter) thought to have formed during the pre-Nectarian period. We combine Lunar Reconnaissance Orbiter imagery, topography, and Moon Mineralogy Mapper compositional data to interpret the surface and subsurface geology of the Smythii basin with the goal of identifying datable impact melt for investigation by a future lunar lander. Surface outcrops exposed on the central peak of the Schubert C crater are identified as uplifted deposits of Smythii impact melt, and a mission concept is presented for sampling these exposures in order to establish the absolute age of the Smythii basin using radioisotopic geochronology. This mission concept is in line with one of the current top-tier priorities for lunar science: determining the age of large basins and thus constraining the impact flux during the Moon's first billion years, which is a proxy record for the role of impacts on the surface environment and habitability of early Earth and the inner solar system during this interval.

Resumen

To investigate the functional conservation of cis regulatory elements controlling AGAMOUS (AG) expression, we placed the promoter region of AG from Arabidopsis thaliana into a close relative, Brassica napus, and a distantly related species, Linum usitatissimum, and analyzed the subsequent expression patterns in each species. Spatially, the expression patterns in all three species were marginally similar, in that expression was confined primarily to the reproductive organs and nectarium. Within organs however, tissue-specific expression patterns were not conserved between species. Unlike Arabidopsis, the transgenic AG cis elements did not express in the ovules of B. napus and L. usitatissimum. Temporally, the pattern of AG cis-element expression in B. napus was identical to that of Arabidopsis during early development; however, the AG cis elements did not express at all during early flower development in L. usitatissimum. These results suggest that although regulatory factors controlling the generalized local expression of AG have been conserved between these species, those controlling temporal and tissue-specific expression have not.Key words: AGAMOUS, cis elements, regulation, Arabidopsis, Brassica napus, Linum usitatissimum.

Resumen

Abstract The South Pole–Aitken (SPA) basin, located between the South Pole and Aitken crater on the far side of the Moon, is the largest confirmed lunar impact structure. The pre-Nectarian SPA basin is a 2400 × 2050 km elliptical structure centered at 53°S, 191°E, which should have exposed lower crust and upper mantle due to the enormous excavation depth. Olivine, the dominant mineral in Earth’s mantle, has only been identified in small and localized exposures in the margins of the SPA basin, and the dominant mafic component is, instead, pyroxene. These mineralogical characteristics could be explained by the recent hypothesis that the lunar upper mantle is dominated by low-calcium pyroxene, not olivine. Here, we present observations from imaging and spectral data from China’s Chang’E-4 (CE-4) lunar mission in the first 4 synodic days, especially the first in situ visible/near-infrared spectrometer observations of an exposed boulder. We identified a variety of rock types, but not the recently reported olivine-rich materials in the landing region. The results are consistent with orbital observations. The obtained mineralogical information provides a better understanding of the nature and origin of SPA materials.

Resumen

The Nectarian-aged Crisium basin exhibits an extremely thin crust and complicated lunar geological history. This large multi-ring impact basin is characterized by prolonged lunar volcanism ranging from the Imbrian age to the Eratosthenian period, forming the high-Ti mare unit, low-Ti mare basalts, and very low-Ti mare unit. We produced an updated geological map of the Crisium basin and defined four mare units (Im1: 3.74 Ga; Im2: 3.49 Ga; Im3: 3.56 Ga; EIm: 2.49 Ga) in terms of distinct composition and mineralogy. Olivine was widely determined in the Ti-rich Im1, implying the hybridization source in the lunar mantle with the occurrence of small-scale convective overturn. The major phase of low-Ti basaltic volcanism occurred c.a. 3.5 Ga, forming Im2 and Im3 in the western area. The youngest mare unit (EIm) has slight variations of pyroxene compositions, implying a decrease of calcic content of basaltic volcanisms with time. Later, distal material transports from large impact events in highlands could complicate the mixing of local mare basalts in the Copernicus age, especially the Im3 unit. The identified olivine-bearing outcrops and widely Mg-rich materials (Mg# > 70, where Mg# = molar 100 × Mg/(Mg + Fe)) in the western highlands, assumed to be the occurrence of the Mg-suite candidates, require future lunar exploration missions to validate.

Resumen

Apricot is one of the important stone fruits produced in the world. In this study, genetic variation was investigated based on SRAP marker technique and morphological data in 120 genotypes and parent plants obtained by inbreeding in some apricot cultivars such as Ninfa, Proce de Tyrinthe, Palstein, Hac?halilo?lu, Hasanbey, Aprikoz and Kabaa??. In the study, 15 different combinations of SRAP markers were used and a total of 105 scoreable bands were obtained and 76 of them were determined as polymorphic. The average base lengths of these primers are between 200-1700 bp, the average number of polymorphic bands per primer is 7.0. The mean polymorphism value is 71.64%. The similarity coefficient in the dendrogram created according to the UPGMA method differed between 0.61 and 0.96. According to the dendrogram, 2 main groups were formed. The closest genotypes have a similarity index of 0.96. In the morphological characterization analysis, 120 hybrid individuals were examined with 19 UPOV criteria. No variation was found in terms of petiole nectarium number, dominant numbers and petiole shape characteristics. Variations between hybrids were determined in terms of 16 characteristics such as plant development, plant habitus, amount of branching in the tree, leaf and shoot characteristics. 119 hybrids showed ?reddish brown? coloration, 87 hybrids medium leaf tip, and 116 plants 'double dentate' in terms of incisions of margin. 84 hybrids showed medium petiole incision, 101 hybrids showed medium petiole thickness, and 117 plants showed weak petiole anthocyanin coloration. It is predicted that the morphological and molecular analyzes of the hybrid plants will enable the development of new cultivars and rootstock candidate genotypes. With the results of this study, the genetic variations and morphological classifications determined in the genotypes will guide the further studies on hybrid breeding programs in apricots.

Resumen

The Apollo basin is a well-preserved double-ringed impact basin located on the northeastern edge of the South Pole–Aitken (SPA) basin. The Apollo basin has been flooded and filled with large volumes of mare lavas, indicating an active volcanism history. Based on orbital data, we reveal that the Apollo basin exhibits an overall asymmetric configuration in the distribution of mare basalts as well as its topography, chemical compositions, and crustal thickness. The Apollo basin is an excellent example for assessing the influences of the above factors on mare basalts petrogenesis and evaluating mare basalt genesis models. It was found that the generation of mare basalt magmas and their emplacement in the Apollo basin seems to be strongly related to local thin crust (<30 km), but the formation of basaltic magmas should be independent of the decompression melting because the mare units (3.34–1.79 Ga) are much younger than the pre-Nectarian Apollo basin. The mare basalts filled in the Apollo basin exhibits a large variation of TiO2 abundances, indicating the heterogeneity of mantle sources, which is possible due to the lunar mantle overturn after the LMO solidification or the impact-induced mantle convection and migration. However, the prolonged mare volcanic history of the Apollo basin is not well explained, especially considering the low Th abundance (<2 ppm) of this region. In addition, the central mare erupted earlier than other mare units within the Apollo basin, which seems to contradict the predictions of the postbasin loading-induced stresses model. Laboratory investigations of the Chang’E-6 mare basalt samples could possibly answer the above questions and provide new insight into the mare volcanic history of the lunar farside and the connections between mare volcanism and impact basin formation/evolution.

Resumen

Serangga berperan penting pada petumbuhan dan perkembangan serta produktivitas tanaman jambu mete. Di daerah Lombok, Nusa Tcnggara Barat telah diidcntiikasi lebih dari 90 jenis serangga yang meliputi serangga hama, musuh alami, penyerbuk dan serangga lainnya. Helopeltis spp. dan S. indecora merupakan serangga hama yang menonjol di wilayah tersebut. Beberapa musuh alami juga telah ditemukan, terutama semut yang bcrfungsi sebagai predator bagi Helopeltis spp. Akhir-akhir ini ketiga jenis serangga tersebut sering bcrada bersamaan dalam satu tanaman. Oleh sebab itu penelitian ini bertujuan untuk mengetahui pcranan semut dan intcraksinya dengan Helopeltis spp. dan S. indecora. Penelitian dilaksanakan di Dusun Sambik Rindang dan Sambik Jengkel, Lombok Barat dai bulan Mei sampai dengan Nopember 2003 Penelitian tcrdiri atas 3 kegiatan yang satu sama lain saling menunjang, yaitu (a) penelitian lapang, (b) penelitian semi lapang, dan (c) penelitian rumah kaca/pot. Pada penelitian lapang keadaan lingkungan tidak dikendalikan. pengamatan dilakukan dengan penarikan contoh. Penelitian lapang ditunjang oleh penelitian semi lapang, yaitu hanya salah satu faktor lingkungan yang dikendalikan (faktor populasi semut : 0, 5, dan 10 koloni per 5 tanaman). Penelitian semi lapang kemudian ditunjang oleh penelitian rumah kaca/pot. Pada penelitian ini tiga faktor dikendalikan/diperlakukan yaitu populasi semut, populasi Helopeltis dan populasi Sanurus indecora. Hasil pengamatan menunjukkan bahwa hama utama yang dominan di Dusun Sambik Jengkel berbeda dengan hama utama yang dominan di Dusun Sambik Rindang. Di Sambik Jengkel, Helopeltis lebih dominan dibandingkan dengan i'. indecora, walaupun S. indecora ditemukan tapi tidak sebanyak serangan Helopeltis. Di Sambik Rindang terjadi sebaliknya, 5. indecora lebih dominan bila dibandingkan dengan Helopeltis. Semut cukup berperan dalam mengendalikan populasi Helopeltis. Dai data yang diperoleh sampai bulan Oktober 2003 diketahui bahwa persentase pucuk yang terserang Helopeltis lebih kecil pada kelompok-kelompok tanaman yang dibei perlakuan semut, begitu pula populasi nimfa dan imagonya. Tidak demikian yang terjadi dengan ,S'. Indecora, populasi nimfa dan imagonya tidak dipengaruhi oleh kehadiran semut. Pada kelompok tanaman yang dibei perlakuan semut, populasi S. indecora justru lebih banyak. Namun demikian, jumlah bunga yang diserang S. indecora lebih banyak pada pucuk yang tidak ada semutnya. Oleh sebab itu, khusus pada bunga, 5. indecora tidak akan datang kalau pada bunga tersebut ada semutnya. Pada pucuk yang telah diserang 5. indecora, semut tidak mengganggu kecuali kalau Helopeltis tidak ada, semut akan memangsa nimfa-nimfa S. indecora. Kata kunci: Anacardium occidentale, jambu mete, Helopeltis spp., nektar, Sanurus indecora, semut ABSTRACT Role of ants (Oecophylla smaragdina and Dolichoderus sp.) in controlling Helopeltis spp. and Sanurus indecora on cashew plant Insects have important roles in cashew growth and productivity. In Lombok, West Nusa Tenggara, more than 90 kinds of insects have been identiied including pest, natural enemies and pollinators. Helopeltis spp. and S. indecora are the main pests in this area. Ants were found to be the predator of Helopeltis spp. Nowadays the three kinds of insects sometime exist in one plant, therefore the objective of this research was to ind out the interaction among Helopeltis spp., S. indecora and ants. The research was caried out in Sambik Rindang and Sambik Jengkel, West Lombok from May to November 2003. There were 3 activities of research (a) ield trial, (b) semi-ield tial, and (c) glass house trial. In the ield trial, the environment conditions were not treated as ixed variables, the observations were done by sampling This ield trial was supported by semi ield trial, only one factor was used as a treatment (ants population) that had 3 levels : 0, 5, and 10 colonies per 5 plants. The semi ield trial was also supported by glass house trial. In this trial 3 factors were used as treatments ants population, Helopeltis spp. and Sanurus indecora population. The result showed that the main pest found in Sambik Jengkel was different from the main pest found in Sambik Rindang. In Sambik Jengkel, Helopeltis spp. was dominant, while in Sambik Rindang £ indecora. Ants had an impotant role in controlling Helopeltis population. The data obtained up to October 2003 revealed that the percentage of damaged shoots was less in the ants-invested plant than that without ants Meanwhile, the population of 5. indecora was not affected by ants incidence, however the number of flowers atacked by £ indecora were more in the shoots without ants. If shoots were previously attacked by S. indecora, the ants would not bother the insects, but when there was no Helopeltis spp. in the plant, the ants would atack the nymphs of S. indecora. Key words : Anacardium occidentale, cashew plant, ants, Helopeltis spp., nectarc, Sanurus indecora

Resumen

The genus Rosenbergiella is one of the most frequent bacterial inhabitants of flowers and a usual member of the insect microbiota worldwide. To date, there is only one publicly available Rosenbergiella genome, corresponding to the type strain of Rosenbergiella nectarea (8N4T), which precludes a detailed analysis of intra-genus phylogenetic relationships. In this study, we obtained draft genomes of the type strains of the other Rosenbergiella species validly published to date ( R. australiborealis , R. collisarenosi and R. epipactidis ) and 23 additional isolates of flower and insect origin. Isolate S61T, retrieved from the nectar of an Antirrhinum sp. flower collected in southern Spain, displayed low average nucleotide identity (ANI) and in silico DNA–DNA hybridization (isDDH) values when compared with other Rosenbergiella members (≤86.5 and ≤29.8 %, respectively). Similarly, isolate JB07T, which was obtained from the floral nectar of Metrosideros polymorpha plants in Hawaii (USA) had ≤95.7 % ANI and ≤64.1 % isDDH with other Rosenbergiella isolates. Therefore, our results support the description of two new Rosenbergiella species for which we propose the names Rosenbergiella gaditana sp. nov. (type strain: S61T=NCCB 100789T=DSM 111181T) and Rosenbergiella metrosideri sp. nov. (JB07T=NCCB 100888T=LMG 32616T). Additionally, some R. epipactidis and R. nectarea isolates showed isDDH values<79 % with other conspecific isolates, which suggests that these species include subspecies for which we propose the names Rosenbergiella epipactidis subsp. epipactidis subsp. nov. (S256T=CECT 8502T=LMG 27956T), Rosenbergiella epipactidis subsp. californiensis subsp. nov. (FR72T=NCCB 100898T=LMG 32786T), Rosenbergiella epipactidis subsp. japonicus subsp. nov. (K24T=NCCB 100924T=LMG 32785T), Rosenbergiella nectarea subsp. nectarea subsp. nov. (8N4T = DSM 24150T = LMG 26121T) and Rosenbergiella nectarea subsp. apis subsp. nov. (B1AT=NCCB 100810T= DSM 111763T), respectively. Finally, we present the first phylogenomic analysis of the genus Rosenbergiella and update the formal description of the species R. australiborealis , R. collisarenosi , R. epipactidis and R. nectarea based on new genomic and phenotypic information.

Resumen

From the stable remanent magnetization of the Apollo igneous rocks and high-grade breccias the existence of a primeval lunar magnetic field was inferred. The palaeointensities of the samples rise rapidly to a maximum at 3.9 Ga, then decrease exponentially to 3.2 Ga, strongly suggesting that the Moon had a field generated in a core, the existence of which was inferred from its non-hydrostatic figure. Modelling of the Apollo 15 and 16 subsatellite magnetic anomalies, by P. J. Coleman, L. L. Hood and C. T. Russell, gave palaeomagnetic directions of crustal strata. This enabled N pole positions to be calculated, which were empirically found to form three bipolar groups, the mean poles of which define (on the core dynamo hypothesis) three axes of rotation different from the present. These were dated as Pre-Nectarian, Lower Nectarian, and Upper Nectarian-Imbrian. Multi-ring basins of these ages were found to lie close to the corresponding palaeo-equators. The impacting bodies were therefore satellites, not asteroids or comets. Their velocities, before collision, can be shown (from basin asymmetries) to be nearly equatorial. The consequent changes in the moment of inertia tensor by basin formation caused these successive reorientations of the Moon relative to its axis of rotation in space. The three mean poles form a 90° spherical triangle. The explanation is that the Moon had three satellites: the orbits of each decayed, they broke up at the Roche limit into smaller bodies, which produced impact basins near the equator. The Moon then reorientated according to Euler’s principle before the next group of impacts. Lunar palaeomagnetism, and especially the inferences that the Moon has an iron core that segregated late and had a primeval satellite system, may provide important constraints on theories of lunar and planetary formation.

Resumen

Abstract The Mare Moscoviense is an astonishing rare flatland multi-ring basin and one of the recognizable mare regions on Moon’s farside. The mineralogical, chronological, topographical, and morphological studies of maria surface of the Moon provide a primary understanding of the origin and evolution of the mare provinces. In this study, the Chandrayaan-1- M3 data have been employed to prepare optical maturity index, FeO and TiO2 concentration, and standard band ratio map to detect the mafic indexes like olivine and pyroxene minerals. Crater size frequency distribution method has been applied LROC WAC data to obtain the absolute model ages of the Moscoviense basin. The four geological unit ages were observed as 3.57 Ga (U-2), 3.65 Ga (U-1), 3.8 Ga (U-3), 3.92 Ga (U-4), which could have been formed between Imbrain to Nectarian epoch. The M3 imaging and reflectance spectral parameters were used to reveal the minerals like pyroxene, olivine, ilmenite, plagioclase, orthopyroxene-olivine-spinel lithology, and olivine-pyroxene mixtures present in the gabbroic basalt, anorthositic, and massive ilmenite rocks and validated with the existing database. The results show that the Moscoviense basin is dominated by intermediate TiO2 basalts that derived from ol

Resumen

AbstractLinear gravity anomalies (LGAs) on the Moon have been interpreted as ancient magmatic intrusions formed during the lunar expansion. The composition of such ancient subsurface intrusions may offer hints for the lunar thermodynamic state in the initial stage of lunar history. To pose a first compositional constraint on magmatism related to lunar expansion, this study analyzed the spectrum and gravity around craters on LGAs, such as Rowland, Roche, and Edison craters. Using reflectance spectra around the craters, we first surveyed non‐mare basaltic exposures. To test the LGA excavation scenario as a possible origin of the discovered exposures, we then compared the Gravity Recovery and Interior Laboratory data and post‐cratering gravity simulation with the iSALE shock physics code. Our spectral analysis reveals no basaltic exposure around the Rowland crater. Further, the observed termination of LGA at the crater rim contradicts the gravity simulation, which assumes that LGA predates the Rowland crater. These results suggest that LGA formation might postdate the Rowland formation and that lunar expansion lasted even after the Nectarian age. On the other hand, we found that both Roche and Edison craters possess basaltic exposures in their peripheries. Because the gravity reduction inside Roche crater can be reproduced in our simulation, the discovered basaltic exposures are possibly LGA materials ejected from these craters. The composition of those exposures shows that the LGA intrusions at the two locations are composed of low‐titanium magma, indicating that ancient magma during the expansion did not contain ilmenite‐rich melt, perhaps resulting from the low‐ilmenite content of the ancient upper mantle.

Resumen

AbstractWe report on the mineralogical and chemical properties of materials investigated by the lunar rover Yutu-2, which landed on the Von Kármán crater in the pre-Nectarian South Pole–Aitken (SPA) basin. Yutu-2 carried several scientific payloads, including the Visible and Near-infrared Imaging Spectrometer (VNIS), which is used for mineral identification, offering insights into lunar evolution. We used 86 valid VNIS data for 21 lunar days, with mineral abundance obtained using the Hapke radiative transfer model and sparse unmixing algorithm and chemical compositions empirically estimated. The mineralogical properties of the materials at the Chang’E-4 (CE-4) site referred to as norite/gabbro, based on findings of mineral abundance, indicate that they may be SPA impact melt components excavated by a surrounding impact crater. We find that CE-4 materials are dominated by plagioclase and pyroxene and feature little olivine, with 50 of 86 observations showing higher LCP than HCP in pyroxene. In view of the effects of space weathering, olivine content may be underestimated, with FeO and TiO2 content estimated using the maturity-corrected method. Estimates of chemical content are 7.42–18.82 wt% FeO and 1.48–2.1 wt% TiO2, with a low-medium Mg number (Mg # ~ 55). Olivine-rich materials are not present at the CE-4 landing site, based on the low-medium Mg #. Multi-origin materials at the CE-4 landing site were analyzed with regard to concentrations of FeO and TiO2 content, supporting our conclusion that the materials at CE-4 do not have a single source but rather are likely a mixture of SPA impact melt components excavated by surrounding impact crater and volcanic product ejecta.

Resumen

Background: An attempt has been made in this study to identify the limitations encountered by the apple farmers in production and marketing which stall its growth in the study area. The present study has been carried out in the Jammu region of Jammu and Kashmir union territory with special emphasis on selected districts which fall under Chenab Valley, which is mostly hilly terrain and mountainous, as these regions had the highest area and production under apple crop.Methods: The primary data has been collected by survey method by interviewing the apple farmers as well as different market functionaries directly through an especially prepared and pre-tested schedule. The Identified constraints of the farmers in the production and marketing of apple had been ranked by making use of the Garrett’s Ranking Technique.Result: The analysis of the study revealed large number of constraints in the production and marketing of the commercial varieties of apple in a selected area, out of which occurrence of apple disease such as Stem Black, Powdery Mildew, Scab, Nectaria Twig Blight, Alternative Twig Blight, Peppery Dark/Pink Disease. Similarly, some of the common pests reported are: Woolly Aphids, San Jose Scale, Stem Borer, Root Borer, Bark Borer had been the major problem faced by the Growers, high labor cost, lack of latest technical knowledge, high cost of transportation, lack of transportation facilities and costly packing material have been identified as the major problems. In order to overcome the marketing problems of the study area apple producers should be organized as federation, cooperatives and union. The study calls for all government and non-governmental organizations to work together to expand and improve apple production and establish apple marketing hub for tackling the bottlenecks in the expansion of apple crop in the study area.

Resumen

ObjectiveThe objective of this study was to isolate lactic acid bacteria (LAB) from native grasses and naturally fermented silages, determine their identity, and assess their effects on silage quality and bacterial communities of the native grasses of three steppe types fermented for 60 days.MethodsAmong the 58 isolated LAB strains, Limosilactobacillus fermentum (BL1) and Latilactobacillus graminis (BL5) were identified using 16S rRNA sequences. Both strains showed normal growth at 15- 45°C temperature, 3-6.5% NaCl concentration, and pH 4-9. Two isolated LAB strains (labeled L1 and L5) and two commercial additives (Lactiplantibacillus plantarum and Lentilactobacillus buchneri; designated as LP and LB, respectively) were added individually to native grasses of three steppe types (meadow steppe, MS; typical steppe, TS; desert steppe, DS), and measured after 60 d of fermentation. The fresh material (FM) of different steppe types was treated with LAB (1 × 105 colony forming units/g fresh weight) or distilled water (control treatment [CK]).ResultsCompared with CK, the LAB treatment showed favorable effects on all three steppe types, i.e., reduced pH and increased water-soluble carbohydrate content, by modulating the microbiota. The lowest pH was found in the L5 treatment of three steppe types, at the same time, the markedly (p < 0.05) elevated acetic acid (AA) concentration was detected in the L1 and LB treatment. The composition of bacterial community in native grass silage shifted from Pantoea agglomerans and Rosenbergiella nectarea to Lentilactobacillus buchneri at the species level. The abundance of Lentilactobacillus buchneri and Lactiplantibacillus plantarum increased significantly in L1, L5, LP, and LB treatments, respectively, compared with CK (p < 0.05).ConclusionIn summary, the addition of LAB led to the shifted of microbiota and modified the quality of silage, and L. fermentum and L. graminis improved the performance of native grass silage.
