The gene ftsZ plays a central role in division.

Mutations in ftsZ block septum formation and generate filaments.

Overexpression induces minicells by causing an increased number of septation events per unit cell mass.

FtsZ (the protein) recruits a battery of cell division proteins that are responsible for synthesis of the new septum.

Blue light depolarizes membrane of hypocotyl cells and inhibits of growth rate.

This membrane depolarization is caused by the activation of anion channels, which facilitates the efflux of anions such as chloride.
