| Abstract: | Calcineurin B-like proteins (CBLs) and their CBL-interacting protein kinases (CIPKs) are important regulatory network in response to abiotic stresses. The CBL-CIPK system senses and decodes Ca2+-signals through phosphorylation to regulate plant response to abiotic stresses. In this review, the basic structures of CBLs and CIPKs, and their phosphorylation on different substrates, as well as regulatory mechanisms of plants in response to abiotic stresses were summarized. We also put forward a perspective on the future research directions of CBLs and CIPKs, as well as their potential applications in genetic improvement of crops for stress tolerance. |
