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.

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 ...

Phenolic Azo Dye Oxidation by Laccase from Pyricularia oryzae [PDF]

Applied and Environmental Microbiology, 1995
Laccase oxidation of phenolic azo dyes was examined with a commercially available laccase from Pyricularia oryzae as the model. Methyl-, methoxy-, chloro-, and nitro-substituted derivatives of 4-(4(prm1)-sulfophenylazo)-phenol were examined as substrates for this laccase. Only the substituents on the phenolic ring were changed. Among the dyes examined,
