Examples of intracellular chemical gradients in microbes. ( A) CtrA-P gradient in C. crescentus determines asymmetric cell division into swarmer cell (top daughter) and stalked cell (bottom daughter). ( B) Alternating MinD gradients (oscillations) determine FtsZ recruitment at midcell and hence the cell-division plane in E. coli. ( C) Pom1 gradient in fission yeast has a similar function to Min system in bacteria. Relative cell sizes ( A-C) are not drawn to scale.
