Genome-wide association study reveals novel genes conferring sheath blight resistance in rice, highlighting antioxidant defense pathways for crop breeding.

Key Points

Identify genetic loci conferring resistance to rice sheath blight across multiple developmental stages and clarify the molecular defense mechanisms involved.
Conducted a genome-wide association study (GWAS) using single nucleotide polymorphism and haplotype genotyping in 259 diverse rice varieties evaluated at seedling, tillering, and booting stages.
Validated candidate resistance genes using plant overexpression and knockdown assays alongside protein-protein interaction assays.
Identified 653 candidate genes correlated with sheath blight resistance, functionally validating OsRSR1 and OsRLCK5 as resistance-conferring genes.
Observed physical interactions between OsRSR1-CC and OsSHM1, as well as OsRLCK5 and OsGRX20, demonstrating an antioxidant defense mechanism mediated by the glutathione–ascorbic acid pathway and reactive oxygen species regulation.
