We present a comprehensive phylogeny derived from 5 genes, nucSSU, nucLSU rDNA, TEF1, RPB1 and RPB2, for 356 isolates and 41 families (six newly described in this volume) in Dothideomycetes. All currently accepted orders in the class are represented for the first time in addition to numerous previously unplaced lineages. Subclass Pleosporomycetidae is expanded to include the aquatic order Jahnulales. An ancestral reconstruction of basic nutritional modes supports numerous transitions from saprobic life histories to plant associated and lichenised modes and a transition from terrestrial to aquatic habitats are confirmed. Finally, a genomic comparison of 6 dothideomycete genomes with other fungi finds a high level of unique protein associated with the class, supporting its delineation as a separate taxon.
我们呈现了一个基于 5 个基因(nucSSU、nucLSU rDNA、TEF1、RPB1 和 RPB2)的综合性系统发育,涵盖了 356 个分离株和 41 个科(其中 6 个是本卷新描述的),这些分离株和科属于子囊菌门中的散囊菌纲。除了大量以前未定位的谱系外,该纲中的所有目前被接受的目都首次被代表。亚纲拟青霉科被扩展到包括水生目 Jahnulales。基本营养模式的祖先重建支持了从腐生生活史到与植物相关和地衣化模式的许多转变,并且确认了从陆地到水生栖息地的转变。最后,对 6 个散囊菌基因组与其他真菌的基因组比较发现,与该类群相关的独特蛋白质水平很高,支持将其划分为一个独立的分类群。
