Resumen

The terpenoid-dominated essential oils in Australian Myrtaceae mediate many ecological interactions and are important industrially. Of all the significant essential oil-producing families, Myrtaceae is the only one for which there is no molecular information on terpene biosynthesis. Here we summarise available knowledge on terpene biosynthesis and its relevance to the Myrtaceae to provide a foundation for ecological and genetic studies of chemical diversity. There are several steps in the terpene biosynthesis pathway that have potential for influencing the oil yield, profile and composition of leaf oils in Myrtaceae. The biochemical steps that influence oil yield in Myrtaceae probably occur in the steps of the pathway leading up to the synthesis of the terpene backbone. Qualitative differences in oil profiles are more likely to be due to variation in terpene synthases and terpene-modifying enzymes. Most of the information on molecular variation in terpene biosynthesis is based on the analysis of artificially derived mutants but Australian Myrtaceae can provide examples of the same mechanisms in an ecological context.

Resumen

Floral organogeny and development are described for two species of the Acmena alliance: Acmena smithii and Syzygium australe. The Acmena alliance is now regarded as distinct from the fleshy-fruited Myrtoideae s.s. A. smithii develops an hypanthium that resembles that seen in some dry-fruited Myrtaceae but stamen initiation resembles that seen in the fleshy-fruited Luma apiculata. By contrast S. australe has hypanthial development similar to the New Zealand fleshy-fruited Myrtaceae but stamen development resembles that of many dry-fruited Myrtaceae. Both species, therefore, show homoplasy of floral characters with both fleshy and dry-fruited Myrtaceae.

Resumen

Pollen morphology of 44 genera and 101 species from the Myrtaceae tribes Kanieae, Myrteae and Tristanieae was surveyed using scanning electron microscopy (SEM) and light microscopy (LM). Most Myrteae pollen were brevicolpate and granulate, which is unique within Myrtaceae, and these are most likely ancestral characters for this tribe. Two main pollen types were observed in tribe Kanieae, one form being with syncolpate colpi and a distinctive granulate exine, and the other with parasyncolpate colpi and a less ornamented exine. Genera Tristania and Thaleropia of tribe Tristanieae produce the smallest pollen in Myrtaceae, whereas Octamyrtus of tribe Myrteae produces the largest pollen observed in Myrtaceae.

Resumen

Myrtaceae is an important family in the neotropics, being highlighted for its relevance in a wide range of vegetations, including those found within the Espinhaço Mountain Range (EMR). The main goal of the present work was to analyze Myrtaceae floristic composition and vegetation distribution in the municipality of Mucugê, Chapada Diamantina, Bahia. Specimens were analyzed in herbaria, two field expeditions were carried out and a landcover classification was performed through remote sensing. The compiled dataset presented 438 records with valid taxonomical identification, from which 374 records were seen by the authors in herbaria. Nine genera and 66 species of Myrtaceae were found, representing the largest Myrtaceae diversity recorded in Chapada Diamantina so far. Four vegetation classes were detected in the landcover classification (campo rupestre, cerrado sensu lato, caatinga sensu lato, and evergreen forest), encompassing 12 phytophysiognomies validated in situ. Comparisons on species diversity within different classes of vegetation were made by overlapping the vegetation classification and Myrtaceae records, also highlighting a directional sampling effort, being the areas threatened by the agriculture expansion both subsampled and poorly known.

Resumen

Identifying synapomorphic morphological characters is needed to select and then accurately place fossils as calibrations on a phylogeny in molecular-dating analyses. The plant family Myrtaceae, with 130 genera and 5500 species, has nine different pollen types, whereas the fossil pollen record of Myrtaceae, represented by the genus Myrtaceidites, putatively extends back to the Cretaceous and also contains at least nine distinct morphospecies. To reveal potential links between extant and fossil pollen, we optimised pollen characters scored from a recent family-wide review of extant Myrtaceae pollen using scanning electron microscopy (SEM) onto a phylogeny of 111 taxa inferred from two chloroplast (matK and ndhF) and one nuclear (internal transcribed spacer, ITS) loci. Our findings indicate the potential use of colpus morphology in diagnosing pollen types in Myrtaceae, whereas the majority of character states of exine pattern, presence of apocolpial island and pollen width appear to be homoplasious. The results of the present study have implications for understanding the relationship between fossil morphospecies and extant Myrtaceae species, and their reliable choice in molecular dating.

Resumen

We here describe, illustrate and compare with related species Calyptranthes corticosa, Myrcia breviflora, M. cantana, M. castanea, M. divisoria, M. integra, M. laxa, M. longiramea, M. manausensis, M. maraana, M. symmetrica, M. uaioai and Plinia humaitana. Calyptranthes corticosa, from the Brazilian state of Acre, is related to C. paniculata, but is distinguished by its strongly angulate twigs and pauciflorous inflorescences; Myrcia breviflora, from the Brazilian state of Amazonas, is related to M. tafelbergica, but has shorter inflorescences with pentamerous flowers; M. cantana, from the Brazilian state of Roraima, is close to M. saxatilis, but has narrower blades and tetramerous flowers; M. castanea, from Amazonas, is related to M. magnoliifolia, but has persistently pilose, bullate leaves and densely pilose inflorescences and flowers; M. divisoria, from Acre, is related to M. calycampa, but has pilose twigs, larger blades and longer inflorescences with persisting bracts; M. integra, from the Brazilian states of Amazonas and Roraima and the Peruvian department of Loreto, is related to Marlierea umbraticola, but is distinguished by the blades with adaxially raised midvein and tetramerous flowers; M. laxa, from Amazonas, is related to M. aequatoriensis, but has smaller petioles, blades not bullate and pilose flowers; M. longiramea, from Amazonas, is related to M. clusiifolia, but has narrower blades crowded at the top of long branches and tetramerous flowers; M. manausensis, from Amazonas, is related to M. splendens but has blades with larger glandular dots and flowers with ovary longitudinally ridged; M. maraana, from Amazonas, is related to M. obumbrans, but has narrower, discolorous blades and tetramerous flowers; M. symmetrica, from the states of Amazonas and Pará, is close to M. plusiantha, but differs by its mostly acuminate blades, shorter inflorescences and tetramerous flowers; M. uaioai, from Roraima, is related to Myrcia gentryi, being distinguished through its elliptic blades with adaxially raised midvein and consistently solitary flowers, and Plinia humaitana, from Amazonas, is related to P. pinnata, but has shorter, wider blades and seed without hypocotyl. Additionally, conservation status is proposed for all species; nevertheless, considering the fact that several species are known only from one collection a/or by mostly ancient collections, their status attribution is necessarily tentative.

Resumen

Leaf collections made from Lenses A and B of Pit II at the Eocene Alcoa Anglesea locality produced the first Eocene record of mummified leaves of the Myrtaceae. In order to determine their diversity and affinities a set of 19 architectural and cuticular characters was selected with which to analyse the leaves. This character set was tested with 65 extant leaves from 11 species of six genera within the Myrtaceae. Operational taxonomic units were analysed using a semi-Euclidian distance metric and the UPGMA clustering algorithm. Results indicated that the character set and analyses successfully clustered all members of each species used, and in the case of Syzygium loosely clustered most species of the genus that were tested. When applied to 34 fossil Myrtaceae leaves, the character sets and analyses revealed that two distinct fossil leaf taxa were present. The organ genus Myrtaciphyllum Christophel & Lys is proposed for mummified leaves with affinities to the Myrtaceae. Two species are erected: the type species M. undulatum, and M. douglasii. The two species are primarily differentiated on cuticular features. The analyses further showed that, in addition to the two fossil groups being distinct from each other, neither demonstrated close affinities with any of the 11 species of extant Myrtaceae used in the analysis. Two fossil Myrtaceae leaves included from the Miocene Bacchus Marsh locality showed moderate affinity to Myrtaciphyllum undulatum.

Resumen

A América e em especial o Brasil, são ricos em espécies frutíferas tropicais nativas e/ou exóticas de grande potencial fitoquímico. Neste contexto, podemos destacar as espécies da família Myrtaceae que apresentam elevado potencial de uso pela presença de compostos, principalmente de natureza fenólica em suas folhas e frutos. Diante disso, a presente pesquisa objetivou catalogar a biodiversidade das Myrtaceae brasileiras adaptadas à Flórida, EUA. Foram feitas duas visitas de cinco dias cada junto às coleções pertencentes a instituições públicas e privadas no Estado da Flórida, EUA. A primeira a fim de catalogar as Myrtaceae brasileiras existentes e a segunda para observar as alterações fenológicas. Para a realização da fenologia observou-se os padrões de enfolhamento, floração e frutificação. As plantas também foram classificadas quanto ao tipo. Os resultados indicaram que existem alterações fenológicas entre a duas observações realizadas nas espécies brasileiras, com surgimento de flores e/ou frutos. Conclui-se que nas coleções pertencentes a instituições públicas e privadas no Estado da Flórida, EUA, existem 64 Myrtaceae e destas 16 são de origem brasileira, as quais estão totalmente adaptadas ao novo ecossistema: Acca sellowiana (O.Berg) Burret, Eugenia brasiliensis Lam., Eugenia cerasiflora Miq., Eugenia luschnathiana (O.Berg) Klotzsch ex B.D.Jacks., Eugenia pyriformis Cambess., Eugenia stipitata McVaugh, Eugenia uniflora L., Myrciaria dubia (Kunth) McVaugh, Myrciaria floribunda (H.West ex Willd.)

Biodiversity of Brazilians Myrtaceae Adapted to Florida, USA A B S T R A C T America and especially Brazil, are rich in tropical fruit species native and/or exotic big phytochemical potential. In this context, we highlight the species of Myrtaceae family that have high potential for use by the presence of compounds, mainly phenolic nature in its leaves and fruits. Therefore, the present study aimed to describe the biodiversity of Brazilians Myrtaceae adapted to Florida. Two visits five days each were made along the collections belonging to public and private institutions in the State of Florida, USA. The first to catalog existing Brazilians Myrtaceae and second to observe phenological changes. To perform the phenology observed patterns of foliage, flowering and fruiting. Plants were also classified according to type. The results indicated that there are phenological changes between the two observations carried out in Brazilian species, with the emergence of flowers and/or fruits. We conclude that the collections belonging to public and private institutions in the State of Florida, there are 64 Myrtaceae and these 16 are from Brazil, which are fully adapted to the new ecosystem: Acca sellowiana (O.Berg) Burret, Eugenia brasiliensis Lam., Eugenia cerasiflora Miq., Eugenia luschnathiana (O.Berg) Klotzsch ex B.D.Jacks., Eugenia pyriformis Cambess., Eugenia stipitata McVaugh, Eugenia uniflora L., Myrciaria dubia (Kunth) McVaugh, Myrciaria floribunda (H.West ex Willd.)

Resumen

This study was conducted at Pulau Jerejak, Penang to determine the floristic variation of its tree communities. A 0.5-hectare study plot was established and divided into 11 subplots. A total of 587 trees with diameter at breast height (DBH) of 5 cm and above were measured, identified and recorded. The tree communities comprised of 84 species, 63 genera and 32 families. The Myrtaceae was the most speciose family with 10 recorded species while Syzgium glaucum (Myrtaceae) was the most frequent species. The Myrtaceae recorded the highest density of 306 individuals while Syzgium glaucum (Myrtaceae) had the highest species density of 182 individuals. Total tree basal area (BA) was 21.47 m2/ha and family with the highest BA was Myrtaceae with 5.81 m2/ha while at species level, Syzgium glaucum (Myrtaceae) was the species with the highest total BA in the plot with value of 4.95 m2/ha. The Shannon˗Weiner Diversity Index of tree communities showed a value of 3.60 (H'max = 4.43) and Evenness Index of 0.81 which indicates high uniformity of tree species. The Margalef Richness Index (R') revealed that the tree species richness was 13.02. Myrtaceae had the highest Importance Value of 20.4%. The Canonical Correspondence Analysis (CCA) showed that Diospyros buxifolia (Ebenaceae) and Pouteria malaccensis (Sapotaceae) were strongly correlated to low pH. Dysoxylum cauliflorum (Meliaceae) and Eriobotrya bengalensis (Rosaceae) were correlated to phosphorus (P) and calcium ion (Ca2+), respectively. Therefore, the trees species composition at Pulau Jerejak showed that the biodiversity is high and conservation action should be implemented to protect endangered tree species.

Resumen

The Myrtaceae is a very large and diverse family containing a number of economically and ecologically valuable species. In Australia, the family contains approximately 1700 species from 70 genera and is structurally and floristically dominant in many diverse ecosystems. In addition to threats from habitat fragmentation and increasing rates of natural disasters, infection by myrtle rust caused by Austropuccinia psidii is of significant concern to Australian Myrtaceae species. Repeated infections of new growth have caused host death and suppressed host populations by preventing seed set. Although most Myrtaceae species demonstrate orthodox seed storage behavior, exceptional species such as those with desiccation sensitive seed or from myrtle rust-suppressed populations require alternate conservation strategies such as those offered by cryobiotechnology. Targeting seven key Australian genera, we reviewed the available literature for examples of cryobiotechnology utilized for conservation of Myrtaceae. While there were only limited examples of successful cryopreservation for a few genera in this family, successful cryopreservation of both shoot tips and embryonic axes suggest that cryobiotechnology provides a viable alternative for the conservation of exceptional species and a potential safe storage method for the many Myrtaceae species under threat from A. psidii.

Resumen

Abstract Austropuccinia psidii is an invasive pathogenic rust that infects the Myrtaceae family. This rust is a threat to Myrtaceae plantations around the world due to its widespread distribution. In this study, we observed the presence of A. psidii in three species of Myrtaceae, i.e. Melaleuca cajuputi, Syzygium myrtifolium, and Syzygium polyanthum planted in Yogyakarta and Sukabumi. The symptoms of infection were yellow-reddish spot in young leaves, presence of urediniospores in infected spot, foliage, and branch dieback. To confirm the presence of A. psidii on those trees, a molecular detection was performed using specific primer for A. psidii (Ppsi1/Ppsi6) on DNA samples extracted from diseased leaves. The presence of A. psidii was proved by the presence of DNA amplicon sized around 500bp in all samples collected from three different hosts. In this study, S. myrtifolium was firstly reported to be infected by this rust in Indonesia. Further study about the presence and the economic impact of this pathogen in Indonesia should be conducted. Indonesia has many species numbers of Myrtaceae and some species are important for medicines, herbs, foods, and as industrial plants. A strategy to control this pathogen should be established to avoid large economic losses in Myrtaceae plantations in Indonesia.

Aunque su polen se considera moderadamente alergénico, en áreas en las que, como consecuencia de repoblación forestal ocupa extensiones importantes, puede llegar a causar problemas alérgicos.Entre los años 1995 y 2000 se ha realizado el estudio aerobiológico en la ciudad de Vigo mediante un captador LANZONI VPPS 2000 situado en la margen derecha de la ría de Vigo (42°14'15"N, 8°43'30"W). La cantidad de granos de polen anual de Myrtaceae varía ampliamente, alternándose años de concentraciones bajas con otros de valores elevados que representan entre un I y un 3% del polen total anual. El valor más elevado se detectó en 1997 con 1.147 granos de polen. Se encuentra en la atmósfera de Vigo durante todo el año, aunque las concentraciones más importantes se producen generalmente durante los meses de marzo y abril. Asimismo, a lo largo del día los máximos de concentración tienen lugar entre las 15 y las 17 horas. Finalmente se ha realizado un análisis estadístico para poner de manifiesto la posible correlación existente entre las concentraciones de polen y los principales parámetros meteorológicos. El viento procedente del N-NE fue el parámetro con el que se obtuvo correlación positiva y significativa de forma constante, mientras que esta fue negativa con la humedad relativa.Palabras clave. Meteorología, Myrtaceae, Polen, Eucalyptus, Vigo.ABSTRACT. The Eucalyptus pollea and its incidence in the atmosphere of Vigo (N. W. Spain). Eucalyptus globulus Labill. is the most frequent arboreal species of the Myrtaceac family in the surroundings of the city of Vigo, and it constitues abundant and dense forestal masses. Although its pollen can be considered as a moderated allergen, in areas in which Eucalyptus was used in extended reafforestations, it can cause allergenic problems.From 1995 to 2000 a Hirst-type volumetric sampler (Hirst, 1952), LANZONI VPPS 2000 placed in the left bank of the Vigo estuary (42°14'15"N, 8°43'30"W) was used for collecting airborne pollen. From year to year important oscillations in the annual total pollen was observed, alternating years of high concentrations with other of lower values. Eucalyptus pollen counts represent a percentage that vary between I% to 3% of the total pollen, the high quantity being collected in 1997 with 1,147 pollen grains. The Myrtaceae pollen appears in the atmosphere of Vigo all over the year, although the more important concentrations are registered during March and April. Moreover, maximum daily concentrations occur between 17.00 and 18.00 hours. Finally, a statistical analysis has been carried out in order to search for the possible correlations between pollen concentration and the main meteorological parameters. The N-NE wind and relative humidity were the parameters that show the highest correlation coefficients, positive and negative respectively.Key words. Meteorology, Myrtaceae, Pollen, Eucalyptus, Vigo.

Resumen

Species of the Botryosphaeriaceae are important pathogens causing cankers and die-back on many woody plants. In Uruguay, Neofusicoccum eucalyptorum (=Botryosphaeria eucalyptorum), N. ribis (=B. ribis) and B. dothidea have previously been associated with stem cankers on plantation grown Eucalyptus globulus. These fungi also exist as endophytes in healthy Eucalyptus leaves, twigs and stems, typically causing disease after the onset of stress. There is good evidence to suggest that species of the Botryosphaeriaceae, other than those previously reported, could cause cankers on Eucalyptus spp. and native Myrtaceae trees in Uruguay. In this study, we identified the Botryosphaeriaceae present on Eucalyptus spp. and on native Myrtaceae trees, and considered the genetic diversity between isolates found on both groups of hosts. Symptomatic and asymptomatic material was collected countrywide from Eucalyptus spp. and native Myrtaceae. Monosporic cultures were identified based on conidial morphology and comparisons of DNA sequences for the ITS region of the rDNA operon. Results revealed that isolates of the N. parvum-N. ribis complex, and B. dothidea were present on both Eucalyptus spp. and native Myrtaceae. In contrast, N. eucalyptorum was found only on Eucalyptus spp. and Diplodia seriata-related (=B. obtusa) isolates were obtained only from native trees. This study expands the knowledge of the occurrence of Botryosphaeriaceae on native and introduced Myrtaceae in Uruguay.

Resumen

Myrtaceae are represented in Colombia by 24 genera and 167 species, where nine genera and 28 species are introduced (Parra-O. 2015, 2016; Parra & Bohórquez-Osorio 2016). Although a checklist of Colombian Myrtaceae has been recently published (Parra-O. 2016), the continuous study of this family has allowed me to identify five new records for the Country. Cited specimens were examined at COAH, COL, FMB, and HUA; herbarium acronyms follow Thiers (2017).

We describe, illustrate and compare with related species the southeastern Brazilian Calyptranthes arachnicola, C. biconvexa, C. carangola, Eugenia grandissima and Plinia longa. Calyptranthes arachnicola, from the state of Rio de Janeiro, is apparently related to Calyptranthes ursina, differing by its larger blades and pendulous inflorescences; Calyptranthes biconvexa, also from Rio de Janeiro, is apparently related to C. lanceolata, being distinguished by its blades with adaxially biconvex midvein and shorter inflorescences; Calyptranthes carangola, from the state of Minas Gerais, is apparently close to C. curta, differing by its narrower blades, longer inflorescences and narrower bracts; Eugenia grandissima, also from Minas Gerais, is apparently close to E. umbrosa, but has larger leaves and petioles, blades with midvein adaxially raised and larger bracteoles; and Plinia longa, from the state of Espírito Santo, is related to Plinia edulis, differing by its narrowly oblong leaves. Additionally, species are evaluated for their conservation status according to the information available.

Resumen

The diverse floral structures of Australian Myrtaceae are discussed in relation to pollination biology, breeding systems, and ecological and evolutionary relationships. Although the reproductive biology of Eucalyptus has been studied widely, little is known about many of the other genera. The review concludes that additional work is needed on aspects of flower structure, pollination biota, late acting self-incompatibility, secondary pollen presentation and reproductive success.
