Gene Details:

• Gene ID: TraesCS2A02G500400
• Gene Symbol: TaGS2-2Ab
• Gene Name: glutamine synthetase 2
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• Transgenic expression of TaGS2-2Ab significantly increased GS2 abundance and GS activity in leaves.
• Analysis of N use-related traits showed that transgenic expression of TaGS2-2Ab increased root ability to acquire N, N uptake before and after flowering, remobilization of N to grains and N harvest index.
• Field experiments showed that transgenic expression of TaGS2-2Ab driven by its own promoter increased the growth and nitrate influx rate of the roots, postanthesis N uptake, leaf functional duration, NHI, grain N concentration and grain yield under both low and high N conditions.
• These results suggest that TaGS2 plays important role in N use, and the favourable allele TaGS2-2Ab is valuable in engineering wheat with improved N use efficiency and grain yield.
