MULTIFUNCTIONAL PLANT’S CALMODULIN IN HEAT SHOCK SIGNAL TRANSDUCTIONAL PATHWAYS

Abstract

Thermo-stress effects growth, developments and productivity of crops and plant cope with stress by adopting different mechanism including physiological, bio-chemical and genetic. Calmodulin is calcium binding protein in plant with multifunction to modulate thermo-stress by calcium based signaling process. Many diverse types of calcium sensors release owing to varying concentration of calcium (stimulus). In plants, CaM (calmodulin) is the most important calcium sensor. Achievements in designing of complete genomes of different crops have prompted to explicate and classify various CaM binding proteins. Genetic studies on CaM revealed that it contains multiple proteins, unique kinases and transcriptional factors which help the plants in adaptation against heat stress conditions. Crop improvement could be only possible by having satisfactory acquaintance on stress tolerance mechanism and a brief knowledge on CaM and its related proteins would be obliging in order to acquire its proper functions in plant growth and developmental pathways under extreme conditons. However, current review was conducted to check the role of CaM in heat stress modulation in plants and current research evaluation in this prespectives.
