Abstract

Organelle movements involving microtubules and actin filaments are a conspicuous and important feature of many plant cells. Movements have recently been supported in preparations of demembranated cytoplasm and reconstituted from purified proteins. The favored mechanism involves organelles carrying a force-generating ATPase moving along a track provided by either actin filaments or microtubules. Cytoplasmic free Ca(2+) concentration regulates at least some organelle movements.
