Rings and networks: the amazing complexity of FtsZ in chloroplasts

Ralf Reski. Trends Plant Sci. 2002 Mar.

Abstract

Bacteria have proteins that can form filaments and rings, and these are thought to be the evolutionary progenitors of actin and tubulin. Plant homologues of the most intensively studied bacterial FtsZ protein are nuclear-encoded by a small gene family, are plastid-bound and participate in the plastid division process. The hypothesis is put forward that FtsZ and other proteins form a filamentous network in plastids, a plastoskeleton, which keeps these organelles in shape and helps them to divide.
