Gene Details:

• Gene ID: TraesCS7B02G318700
• Gene Symbol: TaHKT9-B
• Gene Name: cation transporter HKT1-like
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• A genome-wide association study (GWAS) and candidate gene association analysis further revealed that TaHKT9-B substantially underlies the natural variation of wheat shoot K+ accumulation under saline soil conditions.
• An auxin responsive element (ARE) within an 8-bp insertion in the promoter of TaHKT9-B is strongly associated with shoot K+ content among wheat accessions.
• This ARE can be directly bound by TaARF4 for transcriptional activation of TaHKT9-B, which subsequently attenuates shoot K+ accumulation and salt tolerance.
• TaHKT8, TaHKT9 and TaHKT10, were identified and negatively regulate the wheat shoot K+ accumulation and salt tolerance.
• TaHKT8, TaHKT9 and TaHKT10 preferentially transported K+.
• TaHKT8, TaHKT9 and TaHKT10 overexpression mediate K+/Na+ homeostasis and attenuate salt tolerance.
