sp. nov., sp. nov. and sp. nov., three new species of endophytes with distinctive morphology and functional traits No Access

Abstract

A growing interest in fungi that occur within symptom-less plants and lichens (endophytes) has uncovered previously uncharacterized species in diverse biomes worldwide. In many temperate and boreal forests, endophytic (Sacc.) Cooke (, , ) are commonly isolated on standard media, but rarely are characterized. We examined 26 isolates of housed at the Gilbertson Mycological Herbarium. The isolates were collected from healthy photosynthetic tissues of conifers, angiosperms, mosses and lichens in Canada, Sweden and the United States. Their barcode sequences (nuclear ribosomal internal transcribed spacer and 5.8S; ITS rDNA) were ≤97% similar to any documented species available through GenBank. Phylogenetic analyses based on two loci (ITS rDNA and translation elongation factor 1-alpha) indicated that two isolates represented , broadening the ecological niche and geographic range of a species known previously from burned soil in Japan. The remaining 24 endophytes represented three previously undescribed species that we characterize here: sp. nov., sp. nov. and sp. nov. Each has a wide host range, including lichens, bryophytes and vascular plants. sp. nov. and sp. nov. have wide geographic ranges. sp. nov. occurs in the Madrean biome of Arizona (USA), where it is sympatric with the other species described here. All three species display protease, chitinase and cellulase activity . Overall, this study provides insight into the ecological and evolutionary diversity of and suggests that these strains may be amenable for studies of traits relevant to a horizontally transmitted, symbiotic lifestyle.
