Abstract
The genus Erysiphe (including Pseudoidium anamorph) is the largest genus in the Erysiphaceae and contains more than 50% of total species of the Erysiphceae. Little is known about phylogenetic structure of this genus. We conducted comprehensive phylogenetic analyses of Microsphaera-lineage, a group occupied derived half in the Erysiphe, using 401 sequences of ITS and 28S rDNA regions. The 401 sequences divided into many small groups by the host genus or family. Although bootstrap supports of deep branches are mostly weak, we identified two deep branches with moderate bootstrap supports, with which the 401 sequences were divided into three big groups. In addition, we identified four big clades consisted of homogeneous sequences from a wide range of host plants beyond family level, i.e., E. aquilegiae clade, E. alphitoides clade, E. quercicola clade, and E. trifoliorum s. lat. clade. Isolates from herbaceous plants were mostly situated in the E. aquilegiae group and most derived group III, while basal part of Microsphaera-lineage were occupied by isolates from woody plants except for E. glycines that was used as an outgroup taxon. This supports our early hypothesis that tree-parasitic powdery mildews have old origin in the Erysiphaceae in general, and host-shift from trees to herbs occurred many times independently during the evolution of powdery mildews. Molecular clock analyses suggested that the divergence of Microsphaera-linage began in ca 20 Ma in the Miocene Epock of the Neogene Period.
