Abstract
Erysiphe gracilis, a powdery mildew of evergreen oak, was divided into four distinct genotypes that have differences beyond species level to each other. Survey using 401 samples collected from wide area of western part of Japan did not show clear difference in geographic distributions among these four genotype. Only genotype II and genotype IV were found on Q. myrsinifolia and Q. salicina, respectively. Genotypes I and III were found only from Q. glauca. All four genotypes were found on Q. glauca. These results strongly suggested that host species is associated with speciation of genotypes. A total of 312 samples of Q. glauca with E. grcilis colonies were collected from four locations in the Mie University Campus to investigate frequency of genotypes I and II every month from May 2015 to Jan 2016. No temporal isolation was found between genotypes I and II. These genotypes frequently co-existed on a single leaf surface, especially at the locations disturbed by human activities. Oak powdery mildews, E. gracilis and Cystotheca wrightii, produced conidia only one month a year and their life cycle was quite different from that of ordinary powdery mildew species. This suggests that these oak powdery mildews developed their unique life cycle to synchronize with the life cycle of evergreen oaks.
