Genome-Wide Identification and Evolutionary Analyses of SrfA Operon Genes in Bacillus.

ABSTRACT: A variety of secondary metabolites contributing to plant growth are synthesized by bacterial nonribosomal peptide synthases (NRPSs). Among them, the NRPS biosynthesis of surfactin is regulated by the SrfA operon. To explore the molecular mechanism for the diversity of surfactins produced by bacteria within the genus Bacillus, we performed a genome-wide identification study focused on three critical genes of the SrfA operon-SrfAA, SrfAB and SrfAC-from 999 Bacillus genomes (belonging to 47 species). Gene family clustering indicated the three genes can be divided into 66 orthologous groups (gene families), of which a majority comprised members of multiple genes (e.g., OG0000009 had members of all three SrfAA, SrfAB and SrfAC
