The role of the CBL–CIPK calcium signalling network in regulating ion transport in response to abiotic stress

摘要: Plants are sessile organisms and have multiple tolerance mechanisms which allow them to adapt the environmental stresses they may be exposed. Key a plant’s of abiotic is ability rapidly detect stress activate appropriate response mechanism. The calcineurin B-like (CBL) CBL-interacting protein kinase (CIPK) signalling pathway flexible Ca2+ network allows plant fine tune its stress, via both pre- post-translational mechanisms. Genes encoding CBLs CIPKs now been identified in variety species. found large gene families CIPKs, each proteins with specific upstream downstream targets, thus providing flexibility required stresses. Characterisation CBL CIPK mutants shown important for survive cold, drought, heat, salinity low nutrient Many involved transport ions through plant, either limiting supply toxic certain tissues or maximising uptake beneficial nutrients from soil. This review will provide an update into current knowledge interactions their role ion during stress.
