CBL-Mediated Calcium Signaling Pathways in Higher Plants

Abstract

Plants are sessile and unable to move away from unfriendly surrounding conditions. Instead, they have developed during evolution very complicated cellular signaling mechanisms in order to cope with unfavorable or harsh environments. Such signaling involves calcium ions that can serve as a ubiquitous second messenger in mediating a wide range of environmental stresses, including biotic and abiotic stresses. It is clear that plant cells have the ability to generate stimulus-specific calcium signals in the cytosol and possess numerous calcium-binding proteins with different properties, which sense and transduce the specific calcium signals to give rise to appropriate and disparate responses. In this present review, we mainly focus on the calcium signal transduction pathways mediated by calcineurin B-like (CBL) proteins, which were most recently identified and represent a unique family of calcium sensors in higher plants.
