Abstract
Calcineurin B-Like and CBL-Interacting Protein Kinase (CBL-CIPK) signaling pathway is extremely crucial for plants’ ability to cope up with various types of abiotic stresses which include salt tolerance, hypoxia and anoxia. Therefore, a number of studies have been undertaken to investigate the role of various partners in CBL-CIPK signaling pathway. Most of those studies have been focused on CBL and CIPK proteins as their interaction triggers the cascade of events which ultimately culminate into plant’s response specific to the type of abiotic stress. Studying CBL-CIPK pathway becomes particularly important in case of field crops. In this article, we have studied CBL-CIPK pathway in wheat and rice exploring structural and functional aspects of their interaction. We have investigated the role of CBL-CIPK pathway in combating the salinity in wheat. We have found that CBL4 protein in wheat interacts with CIPK24 triggering the plant’s salt tolerance response. In case of rice we have studied 10 CBL proteins and have found that CBL6 interacts with CIPK15 to trigger the plant’s response against hypoxia and anoxia. These studies may help develop better varieties which may sustain against various abiotic stresses while yielding high produce.
