A Mesorhizobium japonicum quorum sensing circuit that involves three linked genes and an unusual acyl-homoserine lactone signal.

ABSTRACT: Members of the genus Mesorhizobium, which are core components of the rhizosphere and specific symbionts of legume plants, possess genes for acyl-homoserine lactone (AHL) quorum sensing (QS). Here we show Mesorhizobium japonicum MAFF 303099 (formerly M. loti) synthesizes and responds to N-[(2E, 4E)-2,4-dodecadienoyl] homoserine lactone (2E, 4E-C_12:2-HSL). We show that the 2E, 4E-C_12:2-HSL QS circuit involves one of four luxR-luxI-type genes found in the sequenced genome of MAFF 303099. We refer to this circuit, which appears to be conserved among Mesorhizobium species, as R1-I1. We show that two other Mesorhizobium strains also produce 2E, 4E-C_12:2-HSL. T
