Mining SNP loci and candidate genes for sheath blight resistance in <i>Indica</i> rice using genome-wide association studies.

ABSTRACT: Rice is a vital component of the global food supply chain. Sheath blight (ShB) poses a severe threat to indica rice production, resulting in substantial yield and quality deteriorations. Although chemical control strategies are widely employed, their prolonged use raises concerns about the development of pathogenic resistance. Genome-wide association studies (GWAS) serve as a critical tool for identifying genetic loci associated with ShB resistance. However, current research efforts are constrained by limitations in sample size, environmental influences, and analytical methodologies. Notably, studies on ShB resistance have focused mainly on japonica rice, with indica rice receiving limited attention in GWAS-based investigations. Prioritizing GWAS research targeting ShB
