水稻黄单胞菌(X.oryzae)三型分泌系统(TypeⅢsecretion system,T3SS)效应物(Effector)一直被认为是水稻黄单胞菌最重要的致病因子之一。水稻黄单胞菌水稻致病变种(Xanthomonas oryzae pv.oryzae)和水稻黄单胞菌栖稻致病变种(Xanthomonas oryzae pv.oryzicola)分别引起水稻两大细菌病害水稻白叶枯病(Bacterial leaf blight)和水稻细菌性条斑病(Bacterial leaf streak)。基因组分析揭示,水稻黄单胞菌中至少存在28个类型的T3SS效应物,分为TAL(Transcription activator-like effectors)效应物和non-TAL效应物(Non transcription activator-like effectors)两大类。通过对水稻黄单胞菌中T3SS效应物的数量、种类、结构、宿主靶标等方面进行综述,为全面了解水稻-水稻黄单胞菌互作的分子机理,调控网络以及水稻分子育种提供一种新洞察力。
The X. oryzae Type III secretion system (T3SS) Effector has long been considered as one of the most important virulence factors of X. aeruginosa. Xanthomonas oryzae pv. Oryzae pv.oryzae and Xanthomonas oryzae pv.oryzicola cause two major bacterial diseases of rice bacterial leaf blight (Bacterial leaf blight) ) And Bacterial leaf streaks. Genomic analysis revealed that there are at least 28 types of T3SS effectors in X. aeruginosa, which are divided into TAL (Transcription activator-like effectors) effectors and Non-TAL effectors (Non-TAL effectors). By reviewing the quantities, types, structures and host targets of T3SS in Xanthomonas & lt; RTI ID = 0.0 & gt; xanthomonas, & lt; / RTI & gt; provide a comprehensive understanding of molecular mechanisms, regulatory networks and rice molecular breeding for Xanthomonas oryzae New insight.
