Promoter of the TmHKT1;4-A1 gene of Triticum monococcum directs stress inducible, developmental regulated and organ specific gene expression in transgenic Arbidopsis thaliana.

HKT transporters which mediate Na-specific transport or Na-K co-transport, play an important role in protecting plants from salinity stress by preventing Na-over-accumulation in leaves. In this work, a 1508-bp genomic fragment upstream of the TmHKT1;4-A1 translated sequence from Triticum monococcum has been isolated, cloned, and designated as the ''PrTmHKT1;4-A1'' promoter. Sequence analysis of ''PrTmHKT1;4-A1'' revealed the presence of cis-regulatory elements which could be required for abiotic stress and abscisic acid (ABA) responsiveness.
