The crystal structure of the bacterial potassium import complex KdpFABC shows how ATP hydrolysis is coupled to potassium transport to maintain cellular homeostasis under low potassium conditions.

Salinization of cultivated land and the need to increase agricultural productivity make the development of salt-resistant crops imperative. Field trials show that a durum wheat containing a sodium transporter derived from an ancestral wheat relative produces substantially more grain than a commercial durum wheat lacking this transporter on saline soil.
