Abstract
In Gram-negative bacteria, a typical quorum-sensing (QS) system involves the production and response to N-acyl homoserine lactones (AHLs). It still remains unclear as to how pivotal and conserved AHL QS is in root-colonizing rhizosphere Pseudomonas. We, therefore, performed a systematic study of AHL QS on a set of 50 rice rhizosphere Pseudomonas isolates. We also isolated the AHL QS genes in two representative strains and analyzed the role of AHL QS regulation of various phenotypes. Our results are discussed with the current knowledge of AHL QS of rhizosphere Pseudomonas, implicating a lack of conservation and an unpredictable role played by AHL QS in this group of bacteria.
