Gene Details:

  • Gene ID:
  • Gene Symbol: TaHKT1|5-D
  • Gene Name: high-affinity potassium (K+) transporter
  • Genome:
  • Species: Triticum aestivum

Functional Descriptions:

  • The Na+ transporter, TaHKT1|5-D|TaHKT1|5-D, limits shoot Na+ accumulation in bread wheat.
  • The function of TaHKT1|5-D|TaHKT1|5-D, a candidate gene underlying the Kna1 locus. Transport studies using the heterologous expression systems Saccharomyces cerevisiae and Xenopus laevis oocytes indicated that TaHKT1|5-D|TaHKT1|5-D is a Na+-selective transporter.
  • Transient expression in Arabidopsis thaliana mesophyll protoplasts and in situ polymerase chain reaction indicated that TaHKT1|5-D|TaHKT1|5-D is localised on the plasma membrane in the wheat root stele.
  • This indicates that TaHKT1|5-D|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.
  • TaHKT1|5-D|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.
