摘要

Rice sheath blight, caused by Rhizoctonia solani, is a primary disease threatening global rice production, resulting in significant yield losses. This review explores the resistance mechanisms of the rice crop against sheath blight, focusing on recent advancements in genomics and plant immunology. This review covers key areas, including the identification of sheath blight resistance genes, mapping of Quantitative Trait Loci (QTL) in cultivated rice, and the utilization of wild rice germplasm for disease resistance. This paper examines how phytohormones, transcription factors, and receptor kinases regulate sheath blight resistance in rice. Understanding these mechanisms is essential for developing blight-resistant cultivars and improving management strategies. The findings provide valuable insights for breeding programs focused on enhancing sheath blight resistance in rice.
