Schematic representation of Ca²⁺-mediated pathway involve in salt stress in soybean. Upon salt stress, Ca²⁺ATPase regulate cytosolic Ca²⁺ level. Ca²⁺ signals are amplified and transmitted by Ca²⁺ sensors including calmodulins (CaMs), calmodulin-like proteins (CMLs), calcineurin B-like proteins (CBLs), and calcium-dependent protein kinase (CDPKs). Through interacting with their associated interacting proteins, downstream effectors genes are subsequentially activated to give physiological response countering salt stress. Black boxes indicate functionally verified genes in the Ca²⁺-mediated pathway involve in salt tolerance in soybean
