Genomic organization of the duplicated genomic region. (A) Schematic representation of the first 180 kb of the B. subtilis chromosome. The orange box indicates the duplicated region in the suppressors of rny strain GP2501. rRNA operons are depicted as green rectangles, RNA polymerase genes rpoA, rpoB, rpoC as blue arrows, the ctsR and pdaB genes are shown in yellow and red, respectively. (B) Chromosomal relocation of the rpoA gene. For the color code, see above; the relocated rpoA is shown as a purple arrow.
