【摘要】 植物病原细菌利用Hrp致病岛编码专化性的Ⅲ型泌出系统,这个泌出系统是细菌与寄主植物互作时必要的调节因子。Hrp致病岛含有hrp、hrc和hpa基因,这些基因构成Hrp致病岛的核心区域。其中,hrc基因编码的Hrc蛋白是Ⅲ型泌出系统的组成成分。Ⅲ型效应蛋白和Harpin蛋白是Ⅲ型泌出系统的重要泌出底物,Ⅲ型泌出系统主要是通过Ⅲ型效应蛋白与寄主植物互作。这个互作过程受到一些调节因子控制。更多还原

【Abstract】 Phytopathogenic bacteria employ Hrp pathogenicity island to encode a specific typeⅢsecretion system that is required for bacteria and host plant interaction.The Hrp pathogenicity island contains hrp,hrc and hpa genes constructing a core region.Hrc proteins encoded by the hrc genes are components of the typeⅢsecretion system.TypeⅢeffector and Harpin proteins are important substrates of the secretion system,and the system interacts with host plant via the effector proteins.Meanwhile,some regulatory factors also control the interaction.更多还原
