Research Progress of Plant Calcium Nutrition and Calcium/Cold Signal Interaction

摘要

Calcium, as the second messenger inside plants, is extensively involved in plant response and transduction of various stress signals. Plants shall generate calcium signals of specificity under stress, and this shall give a rise to a series of intracellular physiological and biochemical responses. Calcium ions, under cold stress, are able to lower phase transition temperature of membrane lipids, while also able to strengthen plant cold resistance through maintaining soluble sugar and protein content in cells, and increasing unsaturated lipid or fatty acid content in membrane lipids. A general review of research home and abroad over recent years is presented hereby on plant calcium nutrition and calcium/cold signal interaction and regulation.
