摘要:

钙调磷酸酶B蛋白(CBLs)及其互作蛋白激酶(CIPKs)组成的信号系统是非生物逆境响应的重要调控网络。CBL-CIPK系统通过磷酸化感应并解码Ca2+信号, 参与植物对非生物胁迫的应答调控。该文综述了CBLs和CIPKs结构、CBLs-CIPKs对不同底物磷酸化及其响应非生物胁迫调控机制的研究进展, 并展望了未来的研究方向, 以期为作物抗逆性遗传改良提供思路。

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.

Key words: abiotic stresses, calcium signaling, CBL-CIPK, ion channels, phosphorylation
