Gene Details:

  • Gene ID:
  • Gene Symbol: TaHKT1.5-D
  • Gene Name: HKT8-D homeolog
  • Genome:
  • Species: Triticum aestivum

Functional Descriptions:

  • Transport studies using the heterologous expression systems Saccharomyces cerevisiae and Xenopus laevis oocytes indicated that TaHKT1.5-D is a Na+-selective transporter.
  • This indicates that TaHKT1.5-D retrieves Na+ from the xylem vessels in the root and has an important role in restricting the transport of Na+ from the root to the leaves in bread wheat.
  • These data indicate that the function and phenotypes associated with TaHKT1.5-D are consistent with this gene being responsible for, Kna1, the major leaf Na+ exclusion locus of bread wheat. -TaHKT1.5-D confers the essential salinity tolerance mechanism in bread wheat associated with the Kna1 locus via shoot Na+ exclusion and is critical in maintaining a high K+/Na+ ratio in the leaves.
  • A single nucleotide substitution in TaHKT1.5-D controls shoot Na+ accumulation in bread wheat.
