Photoregulation of cytoplasmic motility

Abstract

Intracellular movement is ubiquitously observed in the plant kingdom and it plays a pivotal role in the regulation of a wide spectrum of activities in plant cells. Well-organized motile apparatuses, which are predominantly composed of actin filaments, microtubules, and their associated proteins, drive respective unique types of intracellular movement. In several types of plant cell, intracellular movements are known to be under the control of light. In many cases, a new pattern of movement of cell organelles and/or smaller cytoplasmic particles is induced in response to light stimuli.
