摘要： Viruses are significant pathogens causing severe plant infections and crop losses globally. The resistance mechanisms of rice to viral diseases, particularly Southern rice black-streaked dwarf virus (SRBSDV), remain poorly understood. In this study, we assessed SRBSDV susceptibility in 20 Xian/indica (XI) and 20 Geng/japonica (GJ) rice varieties. XI-1B accessions in the Xian subgroup displayed higher resistance than GJ accessions. Comparative transcriptome analysis revealed changes in processes like oxidoreductase activity, jasmonic acid (JA) metabolism, and stress response. JA sensitivity assays further linked antiviral defense to the JA pathway. These findings highlight a JA-mediated resistance mechanism in rice and offer insights for breeding SRBSDV-resistant varieties.
