Effect of yofA mutation on the expression of cell division genes. Wild-type (○) and yofA::neo (•) cells were grown in LB medium, and the β-galactosidase specific activities of the following reporter genes were examined: ftsAZ-lacZ, divIB-lacZ, divIC-lacZ, ftsW-lacZ, ftsL-pbpB-lacZ, and rodA-lacZ. The data represent the means of three independent experiments.
