Calcium (Ca 2+ ) plays versatile roles in plant growth and development, as well as in responses to environmental stimuli. Abiotic stressors, including abnormal temperature, drought, salt, heavy metals, and flooding, induce instantaneous and rapid free cytosolic Ca 2+ ([Ca 2+ ] cyt ) elevation, known as Ca 2+ signatures. Ca 2+ signatures are stress-specific and regulated by Ca 2+ flux. Ca 2+ flux contains Ca 2+ influx, which initiates Ca 2+ signatures, and Ca 2+ efflux, which terminates them. Ca 2+ flux is achieved through the co-operation of Ca 2+ channels and pumps. Here, we highlight recent advances in Ca 2+ flux and Ca 2+ channel functions in plant responses to abiotic stress. Ca 2+ influx channels in plants include the hyperosmolarity-gated calcium-permeable channel family of proteins (OSCAs), glutamate receptor-like channels (GLRs), cyclic-nucleotide-gated calcium channels (CNGCs), annexins (ANNs), two-pore channels (TPCs), Piezo channels (PZOs), Mid1-complement activity protein channels (MCAs), and mechanosensitive channels of small conductance (MscS)-like proteins (MSLs). Ca 2+ efflux channels mainly contain Ca 2+ -ATPases and Ca 2+ exchangers. Most Ca 2+ channels have been found to participate in plant responses to single abiotic stress, whereas some are reported to be involved in responses to multiple abiotic stresses. This improved knowledge advances our understanding of Ca 2+ signaling in plant responses to abiotic stress and offers new strategies for cultivating stress-resilient crops.
