Abstract

Summary: Bacteria such as Escherichia coli must coordinate cell elongation and cell division. Elongation is regulated by an elongasome complex containing MreB actin and the transmembrane protein RodZ, which regulates assembly of MreB, whereas division is regulated by a divisome complex containing FtsZ tubulin. These complexes were previously thought to function separately. However, MreB has been shown to directly interact with FtsZ to switch to cell division from cell elongation, indicating that these complexes collaborate to regulate both processes. Here, we investigated the role of RodZ in the regulation of cell division. RodZ localized to the division site in an FtsZ‐dependent manner. We also found that division‐site localization of MreB was dependent on RodZ. Formation of a Z ring was delayed by deletion of rodZ, suggesting that division‐site localization of RodZ facilitated the formation or stabilization of the Z ring during early cell division. Thus, RodZ functions to regulate MreB assembly during cell elongation and facilitates the formation of the Z ring during cell division in E. coli . Abstract : RodZ is a component of Rod complex required for cell elongation in E. coli . We found that, in addition to Rod complex in the cylindrical part of the cell, RodZ localizes to divisome required for cell division dependently on FtsZ tubulin. The division‐site localization of RodZ facilitates the formation of the Z ring during cell division in E. coli.
