Popis:	Two cultivars of potato (Solanum tuberosum L.) were transformed with a barley antiporter gene HvNHX2 driven by the CaMV 35S promoter. The expressed transgene conferred a higher NaCl tolerance to one of the cultivars. Under salt stress, the more salt-tolerant transgenic plants had longer roots, higher dry weight, and suppressed cell expansion as compared to wild-type plants. The salt tolerance of the plants grown in vitro was not accompanied by elevated total sodium in any plant organs tested. Instead, higher potassium was found in roots of transgenic plants. Possible mechanisms of plant salt tolerance are discussed.
