Meroterpenes from Psoralea corylifolia against Pyricularia oryzae

Planta Medica, 2014
Six new meroterpenes, namely, 13-methoxyisobakuchiol (1), 13-ethoxyisobakuchiol (2), 12,13-dihydro-13-hydroxybakuchiol (3), Δ(10)-12,13-dihydro-12-(R,S)-methoxyisobakuchiol (4 and 5), and 15-demetyl-12,13-dihydro-13-ketobakuchiol (6), together with four known ones, namely, Δ(3),2-hydroxybakuchiol (7), Δ(1),3-hydroxybakuchiol (8), bakuchiol (9), and Δ(1,

Evidence ofPyricularia oryzaeadaptability to tricyclazole

Journal of Environmental Science and Health, Part B, 2021
Pyricularia oryzae is the etiological agent of rice blast, the most destructive disease in rice crops and chemical control based on fungicide is the main method used in its management. The aim of this study was characterize pathogenicity and identify P. oryzae isolates adapted to tricyclazole. P.

The chitin deacetylase PoCda7 is involved in the pathogenicity of Pyricularia oryzae

Microbiological Research, 2021
The 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, 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.

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

Role of Energy in Pathogenic Variability of Pyricularia oryzae

Journal of Phytopathology, 1983
Abstract 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.
