Recent Advances in Calmodulin Binding Protein Involved in Plant Responses to Adversity Stresses

Abstract:

Calcium (Ca²⁺) is an important second messenger in plants. The intracellular concentration of Ca²⁺ is often elevated instantaneously under various kinds of biotic and abiotic stresses, and which is recognized by Ca²⁺ signal effectors. By binding to downstream target proteins and regulating their activities, Ca²⁺ participates in the regulation of various physiological activities of plants. Calmodulin binding proteins bind calmodulin in a Ca²⁺-dependent or Ca²⁺-independent manner. The structure characteristics of calmodulin binding proteins identified in plants were reviewed, and emphasizing on how calmodulin binding proteins are involved in regulating plant responses to biotic and abiotic stresses was focused, which would provide a theoretical basis for study of improve disease-tolerance and stress-tolerance of crops.
