The signalling pathways, calcineurin B-like protein 5 (CBL5)-CBL-interacting protein kinase 8 (CIPK8)/CIPK24-salt overly sensitive 1 (SOS1), transduce salt signals in seed germination in Arabidopsis Plant Cell Environ. (IF 7.3) Pub Date : 2024-01-18 Qing Xie, Xiaochang Yin, Yu Wang, Yuting Qi, Chengcai Pan, Sunnatulla Sulaymanov, Quan-Sheng Qiu, Yang Zhou, Xingyu Jiang
For plant growth under salt stress, sensing and transducing salt signals are central to cellular Na+ homoeostasis. The calcineurin B-like protein (CBL)-CBL-interacting protein kinase (CIPK) complexes play critical roles in transducing salt signals in plants. Here, we show that CBL5, an ortholog of CBL4 and CBL10 in Arabidopsis, interacts with and recruits CIPK8/CIPK24 to the plasma membrane. Yeast
