The CaCA superfamily genes in Saccharum: Comparative analysis and their functional implications in response to biotic and abiotic stress

In plants, Calcium (Ca2+) acts as a universal messenger in various signal transduction pathways, including responses to biotic and abiotic stresses and regulation of cellular and developmental processes. The Ca2+/ cation antiporter (CaCA) superfamily proteins play vital roles in the transport of Ca2+ and/or other cations.
