Comparative genomic and transcriptomic analyses reveal habitat differentiation and different transcriptional responses during pectin metabolism in Alishewanella species.

ABSTRACT: Alishewanella species are expected to have high adaptability to diverse environments because they are isolated from different natural habitats. To investigate how the evolutionary history of Alishewanella species is reflected in their genomes, we performed comparative genomic and transcriptomic analyses of A. jeotgali, A. aestuarii, and A. agri, which were isolated from fermented seafood, tidal flat sediment, and soil, respectively. Genomic islands with variable GC contents indicated that invasion of prophage and transposition events occurred in A. jeotgali and A. agri but not in A. aestuarii. Habitat differentiation of A. agri from a marine environment to a terrestrial environment was proposed because the species-specific genes of A. agri were similar to those of soil bacteria, whereas th
