The Gram-negative bacteria Xanthomonas oryzae pv. oryzae, the causative agent of bacterial leaf blight (BLB), received attention for being an economically damaging pathogen of rice worldwide. This damage prompted efforts to better understand the molecular mechanisms governing BLB disease progression. This research revealed numerous virulence factors that are employed by this vascular pathogen to invade the host, outcompete host defence mechanisms, and cause disease. In this review, we emphasize the virulence factors and molecular mechanisms that X. oryzae pv. oryzae uses to impair host defences, recent insights into the cellular and molecular mechanisms underlying host-pathogen interactions and components of pathogenicity, methods for developing X. oryzae pv. oryzae-resistant rice cultivars, strategies to mitigate disease outbreaks, and newly discovered genes and tools for disease management. We conclude that the implementation and application of cutting-edge technologies and tools are crucial to avoid yield losses from BLB and ensure food security.
革兰氏阴性细菌稻黄单胞菌，引起细菌性条斑病（BLB），是一种对全球水稻具有经济破坏性的病原体，因此受到关注。这种损害促使人们努力更好地了解控制 BLB 疾病进展的分子机制。这项研究揭示了许多毒力因子，这些因子被这种血管病原体用来入侵宿主、竞争宿主防御机制并导致疾病。在这篇综述中，我们强调了稻黄单胞菌 pv. 稻种利用来削弱宿主防御的毒力因子和分子机制、宿主-病原体相互作用和致病性成分的细胞和分子机制的最新见解、培育稻黄单胞菌 pv. 稻种抗性水稻品种的方法、减轻疾病爆发的策略以及新发现的用于疾病管理的基因和工具。我们得出结论，实施和应用尖端技术和工具对于避免 BLB 造成的产量损失和确保粮食安全至关重要。
