Gene Details:

• Gene ID: TraesCS7D02G411200
• Gene Symbol: TaHKT2.1-7DL
• Gene Name: high-affinity potassium uptake transporter2
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• The chromosomal region on 7AL containing TaHKT2|1 7AL-1 co-located with QTL for shoot Na+ concentration and yield in some saline environments.
• Evidence indicated that neither TaHKT2|2 nor TaHKT2|1 were associated with primary root Na+ uptake but TaHKT2|1 may be associated with trait variation for Na+ exclusion and yield in some but not all saline environments.
• A recent study, however, showed that TaHKT2|1 is a multigene family consisting of four functional genes and pseudogenes located on the long arm of homeologous group 7 chromosomes with evidence that the individual genes were not involved in controlling Na+ influx from the external medium into roots but may have a role in excluding Na+ from leaves or possibly involved in maintaining K+ status in the plant.
• A two-fold down regulation in TaHKT2|1 7DL-1 expression and up to three-fold down regulation in TaHKT2|2 7AL-1 expression levels indicated that these genes were differentially regulated in control and NaCl treated conditions
