Schematic depicting the relative size (bp), order, and chromosome position of 16S-23S rRNA IGS regions of 3 Vibrio species. This figure shows the relevant genomic regions of V. parahaemolyticus RIMD 2210633 (Chromosome I: NC_004603; chromosome II: NC_004605), V. cholerae O395 (chromosome 1: NC_009456; chromosome 2: NC_009457) and V. vulnificus CMCP6 (chromosome 1: NC_004459; chromosome 2: NC_004460). Sequence coordinates denoting 16S-23S rRNA IGS primer binding sites are listed above and below their respective locus and correspond to the NCBI genome accessions provided here. IGS regions are denoted by open boxes with sizes (in bp) provided within. Directional orientation is indicated for both chromosomes by the 0 min start (0') to the left of each map.
