From: OmpR and RcsB abolish temporal and spatial changes in expression of flhD in Escherichia coli Biofilm
Fluorescence images of flhD::gfp, ompR::gfp, rcsB::gfp in AJW678 and flhD in the ompR and rcsB mutant strains. Biofilms of BP1470, BP1432, BP1462, BP1531, and BP1532 were grown in flow cells and subjected to fluorescence microscopy. Four time points were selected for each strain; these are printed on top of the respective images. At the very top of each column, promoter names are printed. Images were taken at 1,000 fold magnification.
