The MoSR-MoDde1 Regulatory Axis: A Novel Determinant of DMI Sensitivity and a Target for Sustainable Rice Blast Control. [PDF]

Adv Sci (Weinh)
The transcription factor MoSR governs DMI fungicide sensitivity in Magnaporthe oryzae through dual regulation of ergosterol biosynthesis and the detoxification enzyme MoDde1. Targeting MoDde1 via a small‐molecule inhibitor or host‐induced gene silencing enhances DMI efficacy against rice blast, offering a sustainable disease management strategy ...

Field screening for blast resistance gene donors, among rice mutant lines of Mira-1 [PDF]

BIO Web of Conferences
Rice blast disease, caused by Pyricularia grisea was one of the most destructive fungal diseases in rice worldwide. Therefore, resistance breeding requires continuous efforts to enrich the reservoir of resistance rice lines to effectively tackle the ...

Toxins in Blast-diseased Rice Plants [PDF]

Agricultural and Biological Chemistry, 1974
The occurence of tenuazonic acid (T. A.), which had been isolated from the culture broth of blast fungus, in blast-diseased rice plants was surveyed to ascertain whether or not this substance is one of the vivotoxins. T. A. was detected in four of six samples of blast-diseased rice plants, two of which had relatively high T. A.

Rice Blast Prevalence in Smallholder Rice Farmlands in Uganda

Journal of Agricultural Science, 2020
Rice blast disease remains the most important contributor to low and stagnated rice yields in Uganda. However, the role of the smallholder farming system in shaping the prevalence of the disease in the country is not known. In 2015B and 2016A, we surveyed smallholder rice farmlands in 27 districts of Uganda and recorded blast incidence, severity, and ...

Roles of Peroxisomes in the Rice Blast Fungus [PDF]

BioMed Research International, 2016
The rice blast fungus,Magnaporthe oryzae, is a model plant pathogenic fungus and is a severe threat to global rice production. Over the past two decades, it has been found that the peroxisomes play indispensable roles duringM. oryzaeinfection. Given the importance of the peroxisomes for virulence, we review recent advances of the peroxisomes roles ...

Phenotypic and Genotypic screening of fifty-two rice (Oryza sativa L.) genotypes for desirable cultivars against blast disease.

PLoS ONE, 2023
Magnaporthe oryzae, the rice blast fungus, is one of the most dangerous rice pathogens, causing considerable crop losses around the world. In order to explore the rice blast-resistant sources, initially performed a large-scale screening of 277 rice ...
