Climatic Variables and Virulence May Contribute to the Population Dynamics of Pyricularia oryzae at Local Scale. [PDF]

Microbiologyopen
The Italian population structure of P. oryzae was analyzed using SSR genotyping to identify possible determinants shaping its local genetic diversity, including spatial, temporal, environmental, and biological factors. ABSTRACT Rice blast disease, caused by Pyricularia oryzae Cavara, is the most threatening rice pathogen in Italy.

Structure of African Populations of Pyricularia oryzae from Rice [PDF]

Phytopathology®, 2021
Rice blast, caused by the filamentous ascomycete Pyricularia oryzae, is one of the most devastating diseases of rice. Four genetic clusters were previously identified, and three have a large geographic distribution. Asia is the center of diversity and the origin of most migrations to other continents, and sexual reproduction persisted only in the ...

HAG Effector Evolution in Pyricularia Species and Plant Cell Death Suppression by HAG4

Molecular Plant-Microbe Interactions, 2022
Seventy host-adapted gene (HAG) effector family members from Pyricularia species are found in P. oryzae and three closely related species (isolates LS and 18-2 from an unknown Pyricularia sp., P. grisea, and P.

Evolution and Regulation of a Large Effector Family of Pyricularia oryzae [PDF]

Molecular Plant-Microbe Interactions®, 2021
Plant pathogen effectors play important roles in parasitism, including countering plant immunity. However, investigations of the emergence and diversification of fungal effectors across host-adapted populations has been limited. We previously identified a gene encoding a suppressor of plant cell death in Pyricularia oryzae (syn.

Comparative genomic analysis revealed rapid differentiation in the pathogenicity-related gene repertoires between Pyricularia oryzae and Pyricularia penniseti isolated from a Pennisetum grass

BMC Genomics, 2018
Background A number of Pyricularia species are known to infect different grass species. In the case of Pyricularia oryzae (syn. Magnaporthe oryzae), distinct populations are known to be adapted to a wide variety of grass hosts, including rice, wheat and ...

Genetic Structure of the Rice Blast Pathogen (Magnaporthe oryzae) over a Decade in North Central California Rice Fields. [PDF]

, 2017
Rice blast, caused by the ascomycete Magnaporthe oryzae, is one of the most destructive rice diseases worldwide. Even though the disease has been present in California since 1996, there is no data for the pathogen population biology in the state.
