青枯病是一种寄主范围广、地理分布广、田间持久性强的细菌型植物病原菌。这种土传病原菌是青枯病的病原菌,可侵染主要农作物,从而显著减产。为了有利于感染,细菌通过第三类分泌系统传递操纵植物免疫的效应器。本文综述了青枯病防治策略的相对效率和对青枯病的抗性现状。然后,将描述从模式植物青枯病研究中获得的遗传和分子方面的见解。最后,我将探索从解开青枯病菌无毒和毒力机制中收集的知识如何帮助作物对这种破坏性病原菌产生更持久的抗性。
Ralstonia solanacearum is one of the most devastating bacterial plant pathogens due to its large host range, worldwide geographic distribution and persistence in fields. This soilborne pathogen is the causal agent of bacterial wilt and it can infect major agricultural crops thereby reducing significantly their yield. To favor infection, the bacterium delivers, through the type three secretion system, effectors that manipulate plant immunity. In this review, the relative efficiency of control strategies and existing resistances to R. solanacearum will be presented. Then, the genetic and molecular insights gained from the study of bacterial wilt in model plants will be described. Finally, I will explore how the knowledge gathered from unraveling avirulence and virulence mechanisms of R. solanacearum effectors could help to develop more durable resistances in crop plants toward this destructive pathogen.
