The chitin deacetylase PoCda7 is involved in the pathogenicity of Pyricularia oryzae
Microbiological Research, 2021The fungal cell wall plays an essential role in maintaining cellular integrity and facing complex and changing environmental conditions. Whether a fungus successfully invades a host depends on whether it evades the plant's innate immune system, which recognizes the conserved components of the fungal cell wall, such as chitin.

Heterokaryosis and parasexuality in Pyricularia oryzae Cavara
Canadian Journal of Microbiology, 1976Auxotrophs in three different races of Pyricularia oryzae were obtained following ultraviolet mutagenesis, and tested for complementarity on minimal medium. Prototrophic growth resulted between combinations of different auxotrophs of single strains, but not between strains.

Mechanism of resistance to pyrazophos in Pyricularia oryzae
Netherlands Journal of Plant Pathology, 1980Pyrazophos-resistant strains ofPyricularia oryzae were isolated from sectors in colonies of the fungus on a pyrazophos-containing agar medium. In contrast to the wild-type strain, resistant strains did not metabolize pyrazophos (Afugan, Curamil) into its phosphate analogue and 2-hydroxy-5-methyl-6-ethoxycarbonylpyrazolo(1,5-a)pyrimidine (PP), which is ...

Studies on the Sporulation of Pyricularia Oryzae Cav.
Madras Agricultural Journal, 1971It has been the experience of many Research workers engaged in the study of rice blast disease that considerable difficulties are being encountered in securing sufficient amount of sporulation in culture while multiplying the pathogen for inoculation purposes. It is also known that unless the spore load is of sufficient magnitude successful results are

Emergence and spread of the multihost pathogen Pyricularia oryzae
, 2018 The cereal pathogen Pyricularia oryzae (syn. Magnaporthe oryzae), the causal agent of rice and wheat blast, is both a threat to global food security and a model for plant pathology. Despite the clear importance of understanding species boundaries and the distribution of intra-specific diversity for molecular plant pathology, disease surveillance and ...

Role of Energy in Pathogenic Variability of Pyricularia oryzae
Journal of Phytopathology, 1983Abstract Pyricularia oryzae Cav. reacts differently to different varieties. IB race group attacked Zenith for three consecutive years for both rabi and kharif seasons under artificial inoculation condition. Three different isolates were obtained in IB race which differed in their pathogenicity giving a constant susceptible reaction to Zenith.

Action of the antipenetrant, tricyclazole, on appressoria of Pyricularia oryzae
Physiological Plant Pathology, 1983The antipenetrant, tricyclazole, blocked melanin biosynthesis and protected unwounded, but not wounded, rice plants from infection by a wild-type isolate of Pyricularia oryzae. Two "buff mutants" genetically deficient in melanin biosynthesis infected wounded but not unwounded plants.

Overwintering of Pyricularia oryzae in wild infected foxtails
Journal of General Plant Pathology, 2017The rice blast fungus Pyricularia oryzae mainly overwinters in infested rice organs stored indoors, whereas it is difficult or impossible for the pathogen to overwinter outdoors. By contrast, blast pathogens infecting weed grasses must overwinter outdoors every winter to continue their life cycle.
