Origin and evolution of the powdery mildews (Ascomycota, Erysiphales)
Molecular phylogeny suggests a close relationship of Asteraceae to the early evolution of Golovinomyces. The family Asteraceae, with a geographic origin in South America, expanded into the Northern Hemisphere, where it may have been infected by an ancestor of Golovinomyces, thus starting a close hosteparasite relationship. Using this event as a calibration point, we designed molecular clocks fo...
متن کاملMolecular identification of some anamorphic powdery mildews (Erysiphales) in Guilan province, north of Iran
In this study, ITS–rDNA region was used to identify some anamorphic powdery mildews in Guilan province. According to the results, Erysiphe species on Vicia faba and Sesbania punicea showed 100% similarity to each other, however, without ITS sequence of holotype of E. sesbaniae it is impossible to make conclusion whether Vicia faba powdery mildew fungus actually belongs to E. sesbaniae or E. tri...

متن کاملMolecular phylogenetic analyses reveal a close evolutionary relationship between Podosphaera (Erysiphales: Erysiphaceae) and its rosaceous hosts
Podosphaera is a genus of the powdery mildew fungi belonging to the tribe Cystotheceae of the Erysiphaceae. Among the host plants of Podosphaera, 86 % of hosts of the section Podosphaera and 57 % hosts of the subsection Sphaerotheca belong to the Rosaceae. In order to reconstruct the phylogeny of Podosphaera and to determine evolutionary relationships between Podosphaera and its host plants, we...
