Transcriptome Profiling Reveals the EanI/R Quorum Sensing Regulon in Pantoea Ananatis LMG 2665^T.

ABSTRACT: Pantoea ananatis LMG 2665^T synthesizes and utilizes acyl homoserine lactones (AHLs) for signalling. The complete set of genes regulated by the EanI/R quorum sensing (QS) system in this strain is still not fully known. In this study, RNA-sequencing (RNA-seq) was used to identify the EanI/R regulon in LMG 2665^T. Pairwise comparisons of LMG 2665^T in the absence of AHLs (Optical density (OD)₆₀₀ = 0.2) and in the presence of AHLs (OD₆₀₀ = 0.5) were performed. Additionally, pairwise comparisons of LMG 2665^T and its QS mutant at OD₆₀₀ = 0.5 were undertaken. In total, 608 genes were differentially expressed between LMG 2665^T at OD₆₀₀ = 0.5 versus the same strain at OD₆₀₀ = 0.2 and 7
