FIG 6.
FtsA overproduction affects the structure of Z rings formed by mNG-FtsZ and mNG-ΔCTL. (A and B) Phase-contrast, epifluorescence, and merged images of cells induced with xylose to drive expression of mNG-FtsZ and empty vector (EV) or ftsA from the PxylX promoter for 6.5 h prior to imaging. (C and D) Phase-contrast, epifluorescence, and merged images of cells induced with xylose to drive expression of mNG-ΔCTL and empty vector (EV) or ftsA from the PxylX promoter for indicated times prior to imaging. Colored insets in merged images from 5-h time points are expanded below to increase visibility of Z-ring structures. Scale bars, 2 μm. Strains are as indicated.
