Outline of Final Research Achievements

Phylogenetic significance of asexual morphs in dothideomycetous fungi was evaluated to propose a new undertaking in fungal systematics coped with the discontinuation of dual nomenclature of pleomorphic fungi. Morphological examinations and phylogenetic analyses using SSU, LSU, and ITS nrDNA, and TEF1 sequences were carried out for sexual and asexual species in Dothideomycetes to understand their ordinal and familial placements. Several lineages which mostly include species with asexual morphs, such as Periconiaceae and Dictyosporiaceae, were recognized as natural phylogenetic groups. Therefore, phenotypic characters of asexual fungal species were considered as significant phylogenetic indicators for evaluating evolutionary relationships among Dothideomycetes.
