Pseudomonas cyclic lipopeptides suppress the rice blast fungus Magnaporthe oryzae by induced resistance and direct antagonism [PDF]

open access: yes, 2019
Beneficial Pseudomonas spp. produce an array of antimicrobial secondary metabolites such as cyclic lipopeptides (CLPs). We investigated the capacity of CLP-producing Pseudomonas strains and their crude CLP extracts to control rice blast caused by ...

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

open access: yesPest 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,

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

open access: yesMolecular 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 ...

Effect of Light on Sporulation of Pyricularia oryzae Cavara

open access: yesJapanese Journal of Phytopathology, 1970
Spore production of Pyricularia oryzae was relatively abundant on rice straw decoction plus V-8 juice agar (R+V-8), rice straw decoction agar (R), yeast starch agar (Y) and V-8 juice agar (V-8), but it was poor on oat meal agar (O) and potato decoction agar (P), in 7 days culture at 27°C in darkness.The spore production of the fungus on these media in ...

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

open access: yesCrop 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.

Bioactive Phytochemical Compounds in Medicago sativa L. (Alfalfa): A Systematic Review of Biological Properties and Therapeutic Relevance in Nutraceutical and Functional Food Implications

open access: yesFood Frontiers, Volume 7, Issue 2, March 2026.
ABSTRACT Medicago sativa L. (alfalfa) harbors a remarkably diverse reservoir of bioactive secondary metabolites. Flavonoids, isoflavones, and triterpenoid saponins dominate its bioactivity landscape, driving potent antioxidant, anti‐inflammatory, antimicrobial, estrogenic, hypolipidemic, and cytotoxic actions through redox modulation, membrane ...

Gene Flow between Divergent Cereal- and Grass-Specific Lineages of the Rice Blast Fungus Magnaporthe oryzae

open access: yesmBio, 2018
Delineating species and epidemic lineages in fungal plant pathogens is critical to our understanding of disease emergence and the structure of fungal biodiversity and also informs international regulatory decisions. Pyricularia oryzae (syn.
