摘要: 细菌、卵菌以及真菌体内广泛存在着一类分泌蛋白即效应因子(effector),它们在病原微生物和寄主互作过程中发挥着重要作用。根据病原微生物与寄主是否属于亲和性互作,效应因子可分为毒性效应因子(Vir)和无毒效应因子(Avr)。介绍了模式病原细菌丁香假单胞杆菌的效应因子和寄主植物体内的R基因,阐述了Avr基因与R基因的互作机制,包括直接识别和间接识别。最后讨论与展望了丁香假单胞杆菌效应因子与植物R基因的互作研究在植物抗病育种上的重要参考价值。

Abstract: Effectors, kind of secreted proteins, are widely existed in bacteria, oomycetes and fungi, which plays an important role in the interaction between pathogenic microorganisms and their hosts. Effectors are classified into avirulence effectors (Avr) and virulence effectors (Vir) according to whether pathogen can compatibly interact with its host or not. This paper introduced the efforts in the typical pathogenic bacteria Pseudomonas syringae and the R genes in host plants, and described the interaction mechanism between Avr genes and R genes, including direct recognition and indirect recognition. Moreover, we discussed and prospected the value of interaction research between Pseudomonas syringae effectors and plant R genes in plant disease resistance breeding.
