摘　　要：为了对青枯菌病原菌的防治及后续研究提供参考,综述了青枯菌基因组的基本特征及主要致病因子,包括胞外多糖I、三型分泌系统和效应蛋白因子、泳动因子、细胞壁降解酶及其对病原菌致病力的作用。采用单一的措施抑制青枯菌单个或几个致病基因的表达很难有效防控农作物青枯病,而利用对青枯菌具有裂解性的噬菌体控制青枯菌,是具应用前景和值得研究的生物防控方法。In order to provide references for control and further study of pathogenic bacteria of R. solanacearurn, the major virulence factors, including extracellular polysaccharide I, swimming motility, cell-wall-degrading enzymes and type III secretion system and its effectors, their contribution to the virulence and pathogenicity of R. solanacearurn were reviewed and discussed. It is difficult to manage and control the bacterial wilt of crops by inhibiting the expression of single or several virulence genes, but the bio-control methods that application of the phages which effecting the R. solanacearum will be a potential strategy and be worthy of study.
