AHL quorum sensing regulates T6SS and volatiles production in rice root-colonizing Enterobacter asburiae AG129.

ABSTRACT: Pseudomonadota (formerly Proteobacteria) commonly use a contact independent cell-cell communication system known as quorum sensing (QS) mediated by N-acyl-homoserine lactone (AHL) signal molecules. The canonical AHL QS system involves a luxI-family gene, which encodes an AHL synthase, and a luxR-family gene, which encodes a transcriptional regulator responsive to the cognate AHL(s). This study involves the AHL QS system of Enterobacter asburiae AG129, a root associated strain isolated from rice (Oryza sativa). Enterobacter asburiae AG129 produces the N-butanoyl homoserine lactone (C4-AHL) signal molecule. Genome sequencing of strain AG129 revealed the presence of a canonical AHL QS system, comprising genetically adjacent easI-like and easR-like genes. A genomic easI knockout mutant was no
