FIGURE 6.

Colony rugosity impaired by the deletion of brpLG. (A) The parent and mutant strains were spotted onto VFMG agar supplemented with 0.02% arabinose and incubated for 24 h. (B) The parent and mutant strains were spotted onto VFMG agar supplemented with 0.02% arabinose and 100 μg/ml kanamycin and incubated for 24 h for complementation experiments. Each colony that represented the mean rugosity from at least three independent experiments was visualized using a stereomicroscope. All images are shown at the same scale, and 1-mm scale bars are shown on the images of the parent strain.
