abstract = {Blumeria graminis, a powdery mildew fungus, is an important plant pathogen that causes serious damage on a variety of cereal crops. In spite of the importance of the pathogen, information on phylogenetic structure within B. graminis is scarce. In this study we conducted phylogenetic analyses of B. graminis based on the DNA sequences of four different DNA regions (ITS, 28S rDNA, chitin synthese 1, and ß-tubulin). The analyses revealed that the protein-coding regions have higher amount of phylogenetic signals than rDNA regions and are useful for phylogenetic analyses of B. graminis. The present phylogenetic analyses revealed distinct nine groups in B. graminis isolates used in this study, which was commonly supported by all trees constructed by four DNA regions. Isolates from a single host genus belonged to a single group except for isolates from Lolium and Bromus, in which the isolates were split into two and three groups, respectively. Isolates from Agropyron, Secale and Triticum formed a distinct clade (Triticum clade) with identical or similar DNA sequences. Hordeum clade was sister of the Triticum clade, and Poa and Avena clades were distantly related to Triticum and Hordeum clades. This phylogenetic relationship of B. graminis is well concordant with the level of reproductive isolation between formae spciales and also with phylogeny inferred from a cytological study. Topology comparisons of fungal tree with host tree suggested that host/parasite co-speciation has occurred in B. graminis, while host-jumping also occurred simultaneously.}
