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

Scientia 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 ...

Seeds coated with Trichoderma atroviride and soil amended with silicon improve the resistance of Lolium multiflorum against Pyricularia oryzae

, 2021
Ryegrass (Lolium multiflorum L.) is a forage species with a high content of protein and good palatability and digestibility. In winter, it is frequently used in southern Brazil as feed for livestock.

A new method to measure EC50 reveals cultivar‐specific fungicide resistance and very high diversity within experimental field populations of Zymoseptoria tritici

Pest Management Science, Volume 82, Issue 4, Page 3613-3624, April 2026.
We isolated Zymoseptoria tritici strains from a diverse wheat field and quantified fungicide resistance using a novel plate assay. We found high diversity in fungicide sensitivity and host–fungicide–pathogen interactions. Abstract BACKGROUND Zymoseptoria tritici causes Septoria tritici blotch (STB), the most damaging wheat disease in Europe. In Europe,

Cyclonerol Derivatives from YM311505

Natural Product Communications, 2014
A new sesquiterpene, 10,11-dihydrocyclonerotriol ( 1 ), together with two known compounds, catenioblin C ( 2 ) and sohirnone A ( 3 ), were isolated from Trichoderma longibrachiatum YM311505, an endophytic fungus of Azadirachta indica .

Molecular Mechanism Underlying Resistance Variation to the Novel Agrochemical Quinofumelin in Fusarium graminearum

Molecular Plant Pathology, Volume 27, Issue 4, April 2026.
The D155T, V179E, V179D and N281A mutations in FgDHODHII altered the binding mode of quinofumelin, resulting in diminished affinity and a negative correlation between binding affinity and the resistance level of these mutants. ABSTRACT Quinofumelin, a quinoline‐based fungicide, demonstrated potent antifungal activity against Fusarium graminearum, the ...

Studies on Mixture Inoculation of Pyricularia oryzae on Rice

Japanese 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 ...

Unraveling genetic diversity and loci conferring leaf blast resistance in East and Southern African rice germplasm

Crop Science, Volume 66, Issue 2, March/April 2026.
Abstract Rice blast remains a major disease, causing severe yield losses in rice‐producing regions and posing a threat to global food security. Understanding genetic variation within germplasms is crucial for identifying locally adapted genotypes with beneficial alleles for improving resistance to this disease.
