Rapeseed CBL4 protein is a calcium sensor protein localized at the plasma membrane.
Rapeseed CBL4 interacted with multiple CIPKs and CIPK24 is one of them.
Rapeseed CBL4 complemented the salt-sensitive phenotype of sos3-1 mutant.
Overexpression of CBL4 in wild-type Arabidopsis enhanced salt tolerance.
Rapeseed CIPK24-CBL network shows difference from Arabidopsis counterparts.
