Phenotypes of a mutant
mreC is essential under normal conditions PubMed. Depletion of MreC leads to a progressive increse in the width and a decreas in the length of the cell. This shape defect is consistent with a role for mreC in cell wall synthesis during elongation and similar to other genes with roles in elongation like rodA and the redundant gene pair pbpA and pbpH (also known as ykuA). Electron microscopy of cells depleted of MreC show regions of the cell where a thick and irregular cell wall has accumulated PubMed and PubMed. mreC can be deleted provided that 0.5 M sucrose and 20 mM Magnesium is provided in the media, mreC is therefore conditionally essentail. The phenotype of the mreC deletion in these conditions is one characterised by extreamly fat and bloated cells that tend to grow in clusters PubMed.
