Comparative analysis of pathogenicity and phylogenetic relationship in Magnaporthe grisea species complex.

Outbreaks of rice blast have been a threat to the global production of rice. Members of the Magnaporthe grisea species complex cause blast disease on a wide range of gramineous hosts, including cultivated rice and other grass species. Recently, based on phylogenetic analyses and mating tests, isolat...
