Abstract:

The signaling system composed of calcineurin B-like proteins (CBLs) and CBL interacting protein kinases (CIPKs) is a key regulatory node in various stress signaling pathways in plants and has become a major area of research focus in the field of plant stress physiology and molecular biology. This review focused on basic functional domains of CBLs and CIPKs, and biological functions and action mechanisms of CBL-CIPK signaling system in responses to various biotic and abiotic stresses, nutrient uptake, and plant hormones.
