摘要: 水稻(Oryza sativa)细菌性条斑病(BLS)是由稻黄单胞菌稻生致病变种(Xoc)引起的一种重要检疫性病害。该病原菌兼具高度遗传多样性和强传播能力, 在种植集约化及气候变暖的双重驱动下, 在我国南方籼稻主产区持续扩散。该文从以下3个方面系统综述了Xoc-水稻互作机制研究进展。(1) 从病原层面解析了II型分泌系统(T2SS)、III型分泌系统(T3SS)及胞外多糖等关键毒性因子的致病机制, 揭示了致病小种的分化规律; (2) 从寄主层面阐明了PTI/ETI介导的抗病信号通路, 综述了抗病(R)基因克隆与感病(S)基因编辑研究进展; (3) 展望了未来的研究方向, 将致力于深度整合多组学技术系统解析Xoc致病信号网络, 依托泛基因组学规模化挖掘具持久广谱抗性的R基因, 创新构建S基因靶向编辑与植物免疫激活协同增效的绿色防控体系, 为BLS的可持续治理提供系统性解决方案。

Abstract: Rice bacterial leaf streak (BLS), caused by Xanthomonas oryzae pv. oryzicola (Xoc), is a significant quarantine disease. The pathogen exhibits both high genetic diversity and strong transmission capabilities. Driven by agricultural intensification and global warming, BLS has been progressively expanding across major indica rice-producing regions in southern China. This review systematically summarizes recent advances in Xoc-rice interaction mechanisms: (1) Pathogen perspective: elucidating pathogenic mechanisms of virulence factors (including T2SS, T3SS, and extracellular polysaccharides (EPS)) and pathovar differentiation patterns; (2) Host perspective: clarifying advances in PTI/ETI-mediated immunity signaling pathways, resistance (R) gene cloning, and susceptibility (S) gene editing; and (3) Future directions: proposing multi-omics approaches to decode Xoc pathogenicity networks, leveraging pan-genomics for large-scale mining of durable and broad-spectrum R genes, and constructing synergistic systems integrating S gene editing with immune activation to establish systematic solutions for sustainable BLS management.
