“…Morphologically, A. arboricola is unique in its conidioma structure that consists of a mixture of conidiogenous cellular clumps, dematiaceous hyphae, and abundant brown, granular matrix materials. This conidomatal structure distinguishes the species from other previously reported endoconidial BMFs that form conidiomata, viz., Phaeotheca (Sigler et al 1981;Tsuneda et al 2004b), Scleroconidioma (Tsuneda et al 2000), Endoconidioma (Tsuneda et al 2004a, b), Endosporium (Tsuneda et al 2008), Celosporium (Tsuneda et al 2010), and Hispidoconidioma (Tsuneda et al 2010). This morphological distinction from other dothidealean endoconidial taxa is further supported by our phylogenetic analysis of the LSU rDNA region, which places A. arboricola in a wellresolved clade that is distinct from other lineages that include endoconidial taxa (Scleroconidioma and Endoconidioma) (Fig.…”

“…Endoconidial BMF genera are morphologically differentiated from each other primarily based on conidioma structure (Tsuneda and Currah 2006;Tsuneda et al 2010). Phylogenetically, endoconidial BMFs are diverse and are distributed among at least five orders in the Ascomycota (sensu Hibbett et al 2007): Capnodiales, Chaetothyriales, Dothideales, Myriangiales, and Pleosporales (Hambleton et al 2003;Tsuneda et al 2004a;Tsuneda and Currah 2006;Crous et al 2007;Tsuneda et al 2008). Some endoconidial BMF species are pathogenic to plants (Tsuneda et al 2001(Tsuneda et al , 2008 or humans (Palencarova et al 1995;de Hoog et al 2000;Chabasse 2002).…”

A new endoconidial black meristematic genus,Atramixtia, associated with declining white spruce and phylogenetically allied to a lineage of dothidealean conifer pathogens

An endoconidial, black meristematic taxon Atramixtia arboricola gen. et. sp. nov. (Dothideales) from the black subicula found on twigs of declining white spruce, Picea glauca (Moench) Voss, in Alberta is described. It is morphologically distinguishable from other endoconidial taxa by the conidioma composed of clumps of endoconidial conidiogenous cells, scattered meristematically dividing cells, dematiaceous hyphae, abundant brown, granular matrix materials, and sometimes plant tissue. Endoconidia also occur in conidiogenous cellular clumps that are not organized into a conidioma but develop directly from stromatic cells on the bark. In culture, it forms similar endoconidial conidiomata and also a mycelial, blastic synanamorph that superficially resembles Hormonema . Atramixtia arboricola is a member of the Dothideales and shows phylogenetic affinities to a clade of conifer-stem and -needle pathogens, including Sydowia and Delphinella , although no teleomorph was found either on the natural substrate or in culture. It has not been determined whether A. arboricola is pathogenic to its host, but the occurrence of abundant intracellular hyphae in the host periderm suggests that the fungus is at least parasitic.

Endophytic Communities of Transgenic Poplar Were Determined by the Environment and Niche Rather Than by Transgenic Events

et al. 2019

Microbial communities associated with plants represent key determinants of plant health, survival, and growth. However, a good understanding of the structural composition of the bacterial and fungal microbiome present in different plant tissues and growing environments, especially in transgenic woody plants, is required. In the present study, we hypothesized that environmental conditions, ecological niches, and transgenic events could influence the community structure of plant-associated microorganisms (bacterial and fungal endophytes). We sampled the root and stem endospheres of field-grown transgenic and non-transgenic poplar trees ( Populus alba × P. berolinensis ) and applied 16S rRNA and internal transcribed spacer amplicon Illumina MiSeq sequencing to determine the bacterial and fungal communities associated with the different plant habitats and tissues. We found that actinobacteria, proteobacteria, bacteroidetes, and firmicutes were the dominant endophytic bacteria, and the fungal community was dominated by dothideomycetes, agaricomycetes, leotiomycetes, and sordariomycetes. In conclusion, transgenic events did not affect the endophytic bacterial and fungal diversity of poplar trees. The bacterial and fungal community structure depends on the pH and the soil organic matter content. Each plant tissue represents a unique ecological niche for the microbial communities. Finally, we identified the indicator operational taxonomic units (OTUs) and core microbiome associated with the different plant tissues of Populus and different environmental conditions. The results provide a basis for further study of host-microbial interactions with the identified abundant OTUs of Populus .

Species of Elsinoë are phytopathogens causing scab and spot anthracnose on many plants, including some economically important crops such as avocado, citrus, grapevines, and ornamentals such as poinsettias, field crops and woody hosts. Disease symptoms are often easily recognisable, and referred to as signature-bearing diseases, for the cork-like appearance of older infected tissues with scab-like appearance. In some Elsinoë-host associations the resulting symptoms are better described as spot anthracnose. Additionally the infected plants may also show mild to severe distortions of infected organs. Isolation of Elsinoë in pure culture can be very challenging and examination of specimens collected in the field is often frustrating because of the lack of fertile structures. Current criteria for species recognition and host specificity in Elsinoë are unclear due to overlapping morphological characteristics, and the lack of molecular and pathogenicity data. In the present study we revised the taxonomy of Elsinoë based on DNA sequence and morphological data derived from 119 isolates, representing 67 host genera from 17 countries, including 64 ex-type cultures. Combined analyses of ITS, LSU, rpb2 and TEF1-α DNA sequence data were used to reconstruct the backbone phylogeny of the genus Elsinoë. Based on the single nomenclature for fungi, 26 new combinations are proposed in Elsinoë for species that were originally described in Sphaceloma. A total of 13 species are epitypified with notes on their taxonomy and phylogeny. A further eight new species are introduced, leading to a total of 75 Elsinoë species supported by molecular data in the present study. For the most part species of Elsinoë appear to be host specific, although the majority of the species treated are known only from a few isolates, and further collections and pathogenicity studies will be required to reconfirm this conclusion.
