Abstract
Pyricularia oryzae and P. grisea are important agents of major diseases on a wide range of gramineous hosts, and while P. oryzae is the most important pathogen causing outbreak of the rice blast, P. grisea is mainly a pathogen of crabgrass. In this study, 103 P. oryzae and 20 P. grisea isolates were collected from seven species of plants, and their phylogeny, pathogenicity, and relationship with host preferences were analyzed to investigate the differences among them from different hosts. Based on phylogenetic analysis of multilocus sequences, 16 isolates from crabgrass and four isolates from green bristlegrass were identified as P. grisea, and another 103 isolates from crabgrass, green bristlegrass, goose grass, foxtail millet, wild millet, rice and sedge belonged to P. oryzae. Results on pathogenicity tests by artificial inoculation demonstrated that six out of ten P. oryzae isolates from rice and three out of 44 P. oryzae isolates from green bristlegrass showed cross-infectivity on green bristlegrass and rice, respectively. Taken together, our results demonstrated that isolates from green bristlegrass and crabgrass consist of both P. oryzae and P. grisea, and that P. oryzae isolates showed cross-infectivity between rice and green bristlegrass, suggesting host shifts may occur for P. oryzae and P. grisea.
