稻瘟病菌（Pyricularia pigmenta，Magnaporthe pigmenta）是禾本科作物上主要的稻瘟病病原菌，被真菌分子病理学家列为10大真菌病原菌中最重要的模式生物。虽然我们现在处于基因组分析的时代，但除了最近的研究进展外，我们还需要了解病原体的分类，分类和寄生虫专业化的历史。在这篇评论中，我们专注于这些相当基本的主题。首先，概述了分类的历史，包括其性别阶段和名称的发现。根据最近的结果Magnaporthaceae菌株的系统发育分析，稻瘟菌的建议，构成一个强大的人口，是不是同源与Magnaporthe salvinii，模式种Magnaporthe。其次，其寄生专业化到主机特定的亚群和种族的遗传机制进行了概述。最后讨论了最近分子生物学数据对抗病育种的意义。
Pyricularia oryzae(Magnaporthe oryzae), a causal agent of blast diseases on staple gramineous crops, is a model organism listed as the most important economically and scientifically of the top 10 fungal pathogens by fungal molecular pathologists. Although we are now in an era of genome-enabled analysis, we need to understand the history of the pathogen’s taxonomy, classification, and parasitic specialization in addition to recent research advances. In this review, we focus on these rather fundamental topics. First, the history of classification, including the discovery of its sexual stage and designation, is overviewed. Based on recent results of phylogenetic analysis of Magnaporthaceae isolates, blast fungi are suggested to constitute a robust population that is not congeneric withMagnaporthe salvinii, the type species ofMagnaporthe. Second, genetic mechanisms involved in its parasitic specialization into host-specific subgroups and races are outlined. Implications of recent molecular data for resistance breeding are discussed.
