Abstract

Ralstonia solanacearum species complex (RSSC) includes soilborne bacterial plant pathogens with worldwide distribution and wide host ranges. Virulence factors are regulated via four hierarchically organized cell-cell contact independent quorum-sensing (QS) signalling systems: the Phc, which uses as signals (R)-methyl 3-hydroxypalmitate [(R)-3-OH PAME] or (R)-methyl 3-hydroxymyristate [(R)-3-OH MAME], the N-acyl homoserine lactone (AHL)-dependent RasI/R and SolI/R systems, and the recently identified anthranilic acid-dependent system. The unique Phc QS system has been extensively studied; however, the role of the two AHL QS systems has only recently been addressed. In this microreview, we present and discuss current data of the SolI/R and RasI/R QS systems in the RSSC. We also present the distribution and frequency of these AHL QS systems in the RSSC, discuss possible ecological roles and evolutive implications. The complex QS hierarchical networks emphasizes the crucial role of cell-cell signalling in the virulence of the RSSC.

Ralstonia solanacearum 物种复合体中的 N-酰基高丝氨酸内酯细胞-细胞扩散信号。
Ralstonia solanacearum物种复合体(RSSC)包括土壤传播的细菌性植物病原体,分布于世界各地,寄主范围广泛。病毒性因子通过四个层次分明的细胞-细胞接触独立法定量感应(QS)信号系统进行调控:Phc(使用(R)-3-羟基棕榈酸甲酯[(R)-3-OH PAME]或(R)-3-羟基肉豆蔻酸甲酯[(R)-3-OH MAME]作为信号)、依赖 N-酰基高丝氨酸内酯(AHL)的 RasI/R 和 SolI/R 系统以及最近发现的依赖蚁酸的系统。对独特的 Phc QS 系统已经进行了广泛的研究;然而,对两种 AHL QS 系统的作用却只是在最近才进行了探讨。在本微综述中,我们介绍并讨论了 RSSC 中 SolI/R 和 RasI/R QS 系统的当前数据。我们还介绍了这些 AHL QS 系统在 RSSC 中的分布和频率,讨论了可能的生态作用和进化意义。复杂的QS分层网络强调了细胞-细胞信号在RSSC毒力中的关键作用。
