The HKT gene family, which encodes K+/Na+ transport proteins of cell membranes, plays a unique role in controlling plant responses to salt stress. The transcriptional activity of the HKT1;4 gene was assessed in root and leaf tissues of bread wheat genotypes (tolerant Murov 2 and sensitive Aran) that differed in salt tolerance. The HKT1;4 transcript was not found in plant leaves. A genotype-specific change in the root-specific expression of the HKT1;4 gene was observed in response to salt stress: expression of a given gene was weakened in the salt-tolerant genotype and increased in the sensitive genotype. The data could be used to improve the salt tolerance of the wheat plant.
