Stable inheritance of Sinorhizobium meliloti cell growth polarity requires an FtsN-like protein and an amidase

Abstract

In Sinorhizobium bacteria, cell elongation takes place only at new cell poles, generated by cell division. Here, Krol et al. show that an FtsN-like protein and a peptidoglycan amidase are crucial for reliable selection of the new cell pole as cell elongation zone.
