WOOD ANATOMY OF Blepharocalyx salicifolius (H.B.K.) Berg
Centro de Pesquisas Florestais - CEPEF Departamento de Ciências Florestais - DCFL Programa de Pós Graduação em Engenharia Florestal - PPGEF, 2008Co-Authors: Denardi Luciano, Marchiori, José Newton CardosoAbstract:O presente trabalho teve por objetivo a descrição da estrutura anatômica da madeira de murta – Blepharocalyx salicifolius (H.B.K.) Berg (Myrtaceae). Foram coletados seis exemplares da espécie, sendo três na região da Serra do Sudeste e três nos Campos de Cima da Serra, RS. Para confecção de lâminas histológicas, seguiu-se a técnica padrão, utilizada no Laboratório de Anatomia da Madeira da Universidade Federal do Paraná. A maceração da madeira foi realizada pelo método de Jeffrey. A estrutura anatômica da madeira coincide, em linhas gerais, com o padrão típico da família, reunindo um grande número de poros estreitos e solitários, com placas de perfuração simples, além de parênquima apotraqueal difuso, raios heterogêneos e fibras com pontoações areoladas. A presença de monocristais rombóides, bem como a ausência de traqueídeos vasicêntricos permite distinguir a espécie de outras Mirtáceas sul-rio-grandenses anteriormente descritas.The purpose of this work is the description of the wood anatomy of Blepharocalyx salicifolius (H.B.K.) Berg (Myrtaceae). There were collected 6 samples of wood, three from Serra do Sudeste and the others from Campos de Cima da Serra - RS. The wood microtechnique followed the standard procedures used in the Wood Anatomy Laboratory of the Federal University of Paraná. For the maceration of wood sticks, the Jeffrey method was used. The wood anatomy agrees, in general lines, with the typical standard of this family, congregating a large number of narrow and solitary vessels, with simple perforation plates, besides diffuse apotracheal parenchyma, heterogeneous rays and bordered pit fibres. The presence of rhomboid chrystals and the absence of vasicentric tracheids permit to discriminate the studied species from other previously described myrtacean woods, that are native of the State of Rio Grande do Sul

Puccinia psidii infecting cultivated Eucalyptus and native Myrtaceae in Uruguay
Mycological Progress, 2011Co-Authors: C.a. Perez, N. A. Altier, Michael J Wingfield, Sofía Simeto, Robert A BlanchetteAbstract:Eucalyptus or guava rust caused by Puccinia psidii is a serious disease of Eucalyptus and other Myrtaceae. In Uruguay, it has been previously found on Eucalyptus globulus and Psidium brasiliensis. Almost nothing is known regarding the occurrence of this pathogen on other Eucalyptus species or native Myrtaceae in that country. In this study, we determined the presence of P. psidii on Eucalyptus species and native Myrtaceae trees in Uruguay and evaluated the pathogenicity of specimens from native myrtaceous hosts on E. globulus and E. grandis. Phylogenetic analyses based on the internal transcribed spacer (ITS) region of the nuclear ribosomal DNA operon were used to confirm pathogen identity. Comparisons of ITS sequences confirmed the identity of P. psidii on Eucalyptus globulus , E. grandis , Myrcianthes pungens , and Myrrhinium atropurpureum var. octandrum. This is the first report of P. psidii on M. atropurpureum var. octandrum . Pathogenicity tests showed that isolates from native Myrtaceae could infect both Eucalyptus species tested, indicating a strong biological relationship between both introduced and native Myrtaceae. This study supplies relevant field data, morphological information, molecular phylogenetic analyses and infection studies that contribute to a better understanding of an important and little studied pathogen.

Endophytic and canker-associated Botryosphaeriaceae occurring on non-native Eucalyptus and native Myrtaceae trees in Uruguay
Fungal Diversity, 2010Co-Authors: C.a. Perez, N. A. Altier, Bernard Slippers, Robert A BlanchetteAbstract:Species of the Botryosphaeriaceae are important pathogens causing cankers and die-back on many woody plants. In Uruguay, Neofusicoccum eucalyptorum , N. ribis and B. dothidea have previously been associated with stem cankers on plantation-grown Eucalyptus globulus . However, very little is known regarding the occurrence and species diversity of Botryosphaeriaceae in native Myrtaceae forests or what their relationship is to those species infecting Eucalyptus in plantations. The objectives of this study were to identify the Botryosphaeriaceae species present as endophytes or associated with cankers in both introduced and native tree hosts in Uruguay, and to test the pathogenicity of selected isolates obtained from native trees on Eucalyptus . Symptomatic and asymptomatic material was collected countrywide from Eucalyptus plantations and native Myrtaceae trees. Single spore cultures were identified based on conidial morphology and comparisons of DNA sequences of the ITS and EF1-α regions. Six Botryosphaeriaceae species were identified. Botryosphaeria dothidea, N. eucalyptorum and specimens residing in the N. parvum-N. ribis complex were isolated from both introduced Eucalyptus and native Myrtaceae trees, whereas Lasiodiplodia pseudotheobromae was found only on Myrcianthes pungens. Diplodia pseudoseriata sp. nov. and Spencermartinsia uruguayensis sp. nov. are novel species found only on native myrtaceous hosts. Pathogenicity tests showed that isolates obtained from native trees and identified as L. pseudotheobromae , N. eucalyptorum and the N. parvum-N.ribis complex are pathogenic to E. grandis . Interestingly, Lasiodiplodia pseudotheobromae has not previously been found on Eucalyptus in Uruguay and represents a potential threat to this host.

Myrtaceae pollen morphology study from bass strait islands australia is effective in separating region specific fossil Myrtaceae pollen types
Review of Palaeobotany and Palynology, 2020Co-Authors: Matthew Adesanya Adeleye, Felicitas Hopf, Simon G. HaberleAbstract:Abstract The identification of Myrtaceae pollen to species level in fossil records has challenged palynologists due to the similarity of pollen grains produced by species in this family. Here, we present a pollen morphological study of the Myrtaceae species found in a specific region of southeastern Australia, the islands of the Furneaux Group in Bass Strait, and apply this to fossil pollen records from the same region to confirm its utility in differentiating Myrtaceae pollen to type level. We examined 23 species of Myrtaceae, belonging to 6 genera, and were able to identify 11 distinct types. The observed Myrtaceae pollen taxa can be confidently separated to genus level, apart from Euryomyrtus, which is indistinguishable from Leptospermum. Specifically, separation to species level is most achievable within the genus Melaleuca, as well as Kunzea and Calytrix, which are each represented by a single species. Conversely, Eucalyptus could only be separated into major types, while Leptospermum species could not be clearly separated, although differences in exine patterns exist. We also demonstrate that our pollen morphological types can be applied to Holocene and Pleistocene fossil records from the Furneaux Group. We recommend that studying the Myrtaceae of a specific area is more helpful in identifying fossil Myrtaceae pollen from that area than using general Myrtaceae pollen morphological descriptions or keys that are not site- or region-specific.

Pollen analysis of Australian honey
2018Co-Authors: J. Kale M. Sniderman, Kia A. Matley, Simon G. Haberle, David J. CantrillAbstract:Pollen analysis is widely used to verify the geographic origin of honeys, but has never been employed in Australia. In this study, we analysed the pollen content of 173 unblended honey samples sourced from most of the commercial honey producing regions in southern Australia. Southern Australian vegetation is dominated by Eucalyptus (Myrtaceae) forests and, as expected, most Australian honeys are palynologically dominated by Eucalyptus, while other important components include Myrtaceae taxa such as Corymbia/Angophora and the tribe Leptospermeae; plus Brassicaceae, Echium, Macadamia, and Acacia. An important feature of the honeys is the number of Myrtaceae pollen morphotypes per sample, which is generally high (mean = 4.6) compared to honeys produced outside of Australia, including Eucalyptus honeys produced in the Mediterranean region, and honeys produced in South America, which has its own rich indigenous Myrtaceae flora. In the latter regions, the number of Myrtaceae morphotypes is apparently generally ≤2. A high number of Myrtaceae morphotypes may be a feasible criterion for authenticating the origin of Australian honeys, since most Australian honey is produced by honey bees mainly working indigenous floral resources. Myrtaceae morphotype diversity is a convenient melissopalynological measure that could be applied even where detailed knowledge of the pollen morphology of the many component genera and species is absent. Palynological criteria developed in Europe for authenticating Eucalyptus honeys should not be relied upon for Australian honeys, since those criteria are not based on samples of Australian honey.
