Pyricularia blast - a threat to wheat cultivation [PDF]

Czech Journal of Genetics and Plant Breeding, 2011
Wheat blast disease caused by Pyricularia grisea (telemorph Magnaporthe grisea) has become a serious restriction on increasing the area and production of the crop, especially in the tropical parts of the Southern Cone Region of South America.

Green synthesis of silver nanoparticles using fermentation extracts from a mangrove soil bacterium: morphological characterization, and antifungal activities against rice blast fungus. [PDF]

Pest Manag Sci
This study synthesized silver nanoparticles (RFE‐AgNPs) with multifaceted inhibitory effects on Pyricularia oryzae using mangrove soil bacterial natural products and evaluated their toxicity effects on Artemia salina. Abstract BACKGROUND Rice blast, caused by Pyricularia oryzae, poses a formidable threat to global rice production.

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.

Pyricularia pennisetigena and Pyricularia urashimae can also cause wheat head blast

European Journal of Plant Pathology, 2023
Pyricularia oryzae pathotype Triticum (PoT) causes wheat blast and is associated with other poaceous hosts. In addition, there are four pathogens of the genus Pyricularia found in or near wheat fields, P. oryzae patotype Lolium (PoL), P. grisea (Pg), P. pennisetigena (Pp), and P. urashimae (Pu).

Pyricularia graminis-tritici , a new Pyricularia species causing wheat blast [PDF]

Persoonia - Molecular Phylogeny and Evolution of Fungi, 2016
Pyricularia oryzae is a species complex that causes blast disease on more than 50 species of poaceous plants. Pyricularia oryzae has a worldwide distribution as a rice pathogen and in the last 30 years emerged as an important wheat pathogen in southern Brazil. We conducted

A Core Effector MoPce1 Is Required for the Pathogenicity of Magnaporthe oryzae by Modulating Catalase-Mediated H₂O₂ Homeostasis in Rice. [PDF]

Mol Plant Pathol
MoPce1, an atypical CAP/PR‐1 family effector, is essential for Magnaporthe oryzae virulence. MoPce1 functions by interacting with the rice catalase OsCATC to disrupt ROS homeostasis, thereby promoting host susceptibility. ABSTRACT Plant pathogens employ a diverse array of effectors to facilitate host colonisation, including evolutionarily conserved ...
