Analysis of a mechanism of regulation of bacterial cell shape by a novel protein RodZ

I have shown that a novel protein RodZ colocalizes with MreB, a bacterial actin, and forms spirals along the long axis of the cell. Thus, we think that RodZ along with MreB regulates the cell length. I found in this study that RodZ localizes at midcell dependently on MreB and FtsZ, a bacterial tubulin. Cells producing RodZ which cannot localize at midcell are wider that cells producing WT RodZ, suggesting that RodZ regulates the cell width as well as the cell length.
