Heterokaryosis and parasexuality in Pyricularia oryzae Cavara

Canadian Journal of Microbiology, 1976
Auxotrophs 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.

Screening Annual Ryegrass for Increased Tolerance to Blast (Pyricularia Oryzae)

XXV International Grassland Congress (IGC 2023), 2023
Annual ryegrass [Lolium perenne L. spp. multiflorum (Lam.) Husnot] is a high-quality forage utilized heavily in the Southeast for pasture and grazing. Gray Leaf Spot (Pyricularia oryzae) is a fungal pathogen that infects gramineous species and is a common problem in perennial and annual ryegrass stands.

Overwintering of Pyricularia oryzae in wild infected foxtails

Journal of General Plant Pathology, 2017
The 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.

Mechanism of resistance to pyrazophos in Pyricularia oryzae

Netherlands Journal of Plant Pathology, 1980
Pyrazophos-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, 1971
It 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
