The fungus Magnaporthe oryzae Couch (anamorph = Pyricularia oryzae Cavara) (previously known as Magnaporthe grisea (Herbert) Barr) (4) causes gray leaf spot disease of perennial ryegrass (Lolium perenne L.) (12). In recent years, this disease has become a serious but sporadic problem for turfgrass managers in the mid-Atlantic and midwestern United States (9,12,16, 20,22). The disease can cause ...

Plant pathogen effectors play important roles in parasitism, including countering plant immunity. However, investigations of the emergence and diversification fungal across host-adapted populations has been limited. We previously identified a gene encoding suppressor cell death Pyricularia oryzae (syn. Magnaporthe oryzae). Here, we report is one 21-member family characterize sequence diversity ...

This article is available online at http://www.jlr.org array of biological mediators, e.g., eicosanoids and leukotrienes in man and to oxylipins and jasmonates in plants and fungi ( 1–4 ). All LOXs belong to the same gene family and usually contain nonheme iron ( 2, 5 ). LOXs have been implicated in physiological and pathophysiological events, ranging from asthma, cancer, and infl ammation in h...

This article presents the results of development a methodology for describing main morphological and cultural traits Pyricularia oryzae Cav. strains widespread in south Russia. At same time, types are identified listed, which make it possible to unambiguously determine uniqueness variety pathogen. The relationships patterns established using cluster statistical analysis identify conditions path...
