To determine the phylogenetic placement of the major groups of higher fungi, we sequenced the DNA sequences from the small-subunit ribosomal RNA (18S rRNA) coding regions from Taphrina wiesneri (synonym: T. cerasi) and Saitoella complicata and compared them to 18S rRNA sequences from the oomycetes, chytridiomycetes, zygomycetes, ascomycetes, and basidiomycetes. Here we demonstrate that the ascomycetes have at least two major evolutionary lineages. Taphrina wiesneri and Saitoella complicata form a monophyletic branch that diverged prior to the separation of other ascomycetes. The same treatment could be accorded to Schizosaccharomyces pombe.
为了确定高等真菌主要类群的系统发育位置,我们对维氏外囊菌(同义词:樱桃外囊菌)和复杂小孢霉的小亚基核糖体RNA(18S rRNA)编码区的DNA序列进行了测序,并将它们与卵菌纲、壶菌纲、接合菌纲、子囊菌纲和担子菌纲的18S rRNA序列进行了比较。在此我们证明,子囊菌纲至少有两个主要的进化谱系。维氏外囊菌和复杂小孢霉形成了一个单系分支,该分支在其他子囊菌纲分化之前就已分化。粟酒裂殖酵母也可作同样处理。
