The ability of crop plants to tolerate high salt concentrations is an agriculturally useful trait. A new study in rice shows that allelic variation in OsHKT8, which encodes a Na+ transporter, contributes to the enhanced capacity of a salt-tolerant variety to maintain shoot K+ homeostasis under NaCl stress.
