Gene Details:

• Gene ID: TraesCS2A02G121000
• Gene Symbol: TaNHX2-2A
• Gene Name: Na+/H+ antiporter 2
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• Our data suggest that TaNHX2 is a endomembrane-bound protein and may primarily function as a K+/H+ antiporter, which is involved in cellular pH regulation and potassium nutrition under normal conditions.
• It appears that osmotic stress is involved in the upregulation of TaNHX2 in addition to an ion-specific signaling component in wheat.
• TaNHX2 expression could complement the sensitivity of AXT3K to NaCl and KCl stresses.
• Functional Characterization of a Wheat NHX Antiporter Gene TaNHX2 That Encodes a K+/H+ Exchanger.
• TaNHX2 has significant sequence homology to NHX sodium exchangers from Arabidopsis, is abundant in roots and leaves and is induced by salt or dehydration treatments.
• The potassium/proton exchanger TaNHX2 functions as a positive regulator in drought resistance in wheat by mediating cross-talk between the stomatal aperture and GABA accumulation.
• The potassium transporter TaNHX2 interacts with TaGAD1 to promote drought tolerance via modulating stomatal aperture in wheat.
