Energy and Electron Transfer Systems of Chlamydomonas reinhardi: II. Two Cyclic Pathways of Photosynthetic Electron Transfer in the Pale Green Mutant.

abstract：:Changes in cytoplasmic Ca2+ concentration ([Ca2+]i) have been proposed to be involved in signal transduction pathways in response to a number of stimuli, including gravity and touch. The current hypothesis proposes that the development of gravitropic bending is correlated with a redistribution of [Ca2+]i in gravistimu...
