Molecular phylogeny reveals the presence of cryptic speciation within Erysiphe japonica (≡ Typhulochaeta japonica), a powdery mildew on Quercus spp.
چکیده انگلیسی

Molecular phylogenetic analyses based on 28S, ITS and IGS rDNA sequences indicate that Erysiphe japonica (≡ Typhulochaeta japonica) consists of two different genetic groups, one group on Quercus aliena, Q. robur and Q. serrata, and another group on Q. crispula var. crispula and Q. crispula var. horikawae. As morphological difference between the two groups are not yet marked distinctly, we suppose that the process of speciation has not yet been finished and propose a new variety, E. japonica var. crispulae, for the latter group based on the difference in host range and the distinct genetic segregation. Quercus robur (pedunculate oak) is a new host of E. japonica.
