Aquaporins and their function in root water transport under salt stress conditions in Eutrema salsugineum

•The root hydraulic conductivity of E. salsugineum was repressed by salt stress.•However, propionic acid, usually used as an aquaporin inhibitor, conversely enhanced the root hydraulic conductivity of E. salsugineum.•The aquaporin family was characterized and two EsPIPs were identified to play a rol...
