Studies on Mixture Inoculation of Pyricularia oryzae on Rice

open access: yesJapanese Journal of Phytopathology, 1969
In order to know whether or not a simple method in which a formula Ra/Sa×Sv/Rv can be employed for calculation of the mutation frequency for virulence in blast fungus strains, the mixture inoculation effect between original (avirulent) and its mutant (virulent) strains was compared among several fungus strains.The existence of the mixture inoculation ...

Cdc25‐Mediated Activation of the Small GTPase RasB Is Essential for Hyphal Fusion and Symbiotic Infection of Epichloë festucae

open access: yesMolecular Plant Pathology, Volume 27, Issue 1, January 2026.
A conserved Cdc25–RasB signalling pathway, essential for hyphal fusion and host infection, is repurposed in Epichloë festucae to maintain a stable mutualistic symbiosis with grass hosts. ABSTRACT Epichloë festucae is a filamentous endophytic fungus that symbiotically colonises the intercellular spaces of aerial tissues in perennial ryegrass without ...

Cytological aspects of incompatible and compatible interactions between rice, wheat and the blast pathogen Pyricularia oryzae

open access: yesScientia Agricola, 2016
Blast, caused by the fungus Pyricularia oryzae, is an important disease affecting rice and wheat yield worldwide. This study investigated the cytological aspects of incompatible (non-host resistance) and compatible (host resistance) rice- (R_Po) and ...

Production of appressoria at the tips of hyphae of Pyricularia oryzae.

open access: yesJapanese Journal of Phytopathology, 1987
Appressoria-like structures (ALS) were formed at the tips of hyphae of the blast fungus in Petri dishes containing PDA or water agar. Some of them germinated in PDA media and produced again a relatively small appressorium at the tip of hypha germinated from the primary appressorium.

Biosynthesized Silver Nanoparticles as a Nanofungicide Against Diverse Phytopathogenic Fungi

open access: yesJournal of Nanotechnology, Volume 2026, Issue 1, 2026.
The biosynthesis of silver nanoparticles (AgNPs) employing biological resources has gained momentum in comparison with chemical synthesis, contributing significantly to the United Nations Sustainable Development Goals. The important features of AgNP biosynthesis include renewability, biodegradability, biocompatibility, nontoxicity, lower cost, and dual
