Characterization of calnexin in soybean roots and hypocotyls under osmotic stress

► Calnexin is a molecular chaperone involved in folding and quality control of proteins. ► The expression of calnexin in soybean seedlings was evaluated under osmotic stress. ► Calnexin accumulation was highly reduced in developed soybean roots under abiotic stresses. ► Calnexin interacts with a 70 kDa heat-shock cognate protein.
