青枯病菌研究进展

Research Progress on Ralstonia solanacearum

细菌性青枯病是由茄科雷尔氏菌(Ralstonia solanacearum)引起的一种世界范围的细菌性土传病害,广泛分布于热带、亚热带及部分温带地区。青枯病菌寄主广泛,可侵染50多个科的200余种植物,给作物生产带来巨大损失。充分了解青枯病菌是进行青枯病防治的重要前提。本文从青枯病菌的菌群分类、基因组结构、致病机制与致病途径、病菌检测等方面做了系统的阐述,并对基于青枯病菌及寄主植物基因组序列信息,研究和探讨青枯病菌致病机制与青枯病防治进行了展望。

Bacterial wilt（BW） caused by Ralstonia solanacearum（Rs） is an important soil-borne disease that spreads worldwide especially in tropical,subtropical,and some temperate regions.It infects hundreds of plant species of more than 50 families and results in huge losses in crop production.Fully understanding Ralstonia solanacearum is very important for controlling bacterial wilt in crop.Therefore,the classification,genomic structure,pathogenesis mechanisms and pathogen detection of Rs,etc.were reviewed in this paper.Moreover,how to control bacterial wilt and study pathogenesis mechanisms of Rs was expected on the base of genomic sequences of the pathogen and its host in the future.
