ABSTRACT
The governing principles and suites of genes for lateral elongation or incorporation of new cell wall material along the length of a rod-shaped cell are well described. In contrast, relatively little is known about unipolar elongation or incorporation of peptidoglycan at one end of the rod. Recent work in three related model systems of unipolar growth (Agrobacterium tumefaciens, Brucella abortus, and Sinorhizobium meliloti) has clearly established that unipolar growth in the Hyphomicrobiales order relies on a set of genes distinct from the canonical elongasome. Polar incorporation of envelope components relies on homologous proteins shared by the Hyphomicrobiales, reviewed here. Ongoing and future work will reveal how unipolar growth is integrated into the alphaproteobacterial cell cycle and coordinated with other processes such as chromosome segregation and cell division.
