The type III secretion system with its delivered type III effectors (T3Es) is one of the main virulence determinants of Ralstonia solanacearum, a worldwide devastating plant pathogenic bacterium affecting many crop species. The pan‐effectome of the R. solanacearum species complex has been exhaustively identified and is composed of more than 100 different T3Es. Among the reported strains, their content ranges from 45 to 76 T3Es. This considerably large and varied effectome could be considered one of the factors contributing to the wide host range of R. solanacearum. In order to understand how R. solanacearum uses its T3Es to subvert the host cellular processes, many functional studies have been conducted over the last three decades. It has been shown that R. solanacearum effectors, as those from other plant pathogens, can suppress plant defence mechanisms, modulate the host metabolism, or avoid bacterial recognition through a wide variety of molecular mechanisms. R. solanacearum T3Es can also be perceived by the plant and trigger immune responses. To date, the molecular mechanisms employed by R. solanacearum T3Es to modulate these host processes have been described for a growing number of T3Es, although they remain unknown for the majority of them. In this microreview, we summarize and discuss the current knowledge on the characterized R. solanacearum species complex T3Es.

Ralstonia solanacearum III型效应子的庞大，多样且强大的武库及其在植物中的功能。

具有其传递的III型效应子（T3E）的III型分泌系统是茄形青枯菌（Ralstonia solanacearum）的主要毒力决定因素之一。青枯菌物种复合体的全效应组已被详尽鉴定，它由100多种不同的T3E组成。在报道的菌株中，它们的含量范围为45至76个T3Es。这个相当大的和多样的effectome可以考虑的促进的广泛宿主范围的因素之一青枯雷尔氏菌。为了了解青枯菌使用其T3E破坏宿主细胞过程，在过去的三十年中进行了许多功能研究。业已表明，与其他植物病原体一样，青枯菌效应子可以通过多种分子机制抑制植物防御机制，调节宿主代谢或避免细菌识别。青枯菌T3Es也可以被植物感知并触发免疫反应。迄今为止，已经针对越来越多的T3E描述了青枯菌T3E调节这些宿主过程的分子机制，尽管对于大多数T3E仍然未知。在此微审中，我们总结并讨论了有关特征的当前知识青枯菌物种复合物T3E。
