FIG. 3.

Localization of GFP-FtsI (top row) and GFP-FtsQ (bottom row). The GFP fusion proteins were expressed, without induction, from the chromosome by using lambda InCh (left column) or from plasmids (right column). Strains expressing GFP-FtsI and GFP-FtsQ from the chromosome are EC436 and EC442, respectively (6, 21), while cells expressing the proteins from plasmids are JOE426 and JOE427, respectively. Cells were grown at 30°C to early log phase and were fixed for fluorescence microscopy as described previously (6).
