Isolation of barley salT gene: Its relation to salt tolerance and to hormonal regulation by abscisic acid and jasmonic acid

A homologous gene to rice salT was isolated from barley and designated as Hv-salT. Since the expression of rice salT was regulated by plant hormones (abscisic acid and jasmonic acid) and salt stress, the effects of these plant hormones and salt stress on the growth of barley seedlings and the expression of Hv-salT were investigated. In contrast to rice salT, almost no changes in the expression of Hv-salT by hormones and salt stress were detected.
