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.
