Gene Details:

• Gene ID: TraesCS7D02G283700
• Gene Symbol: TaARE1-7D
• Gene Name: chloroplast envelope membrane
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• Expression indicated that knock-out of TaARE1 homoeologs could stimulate nitrate transport rather than ammonium transport upon N deprivation.
• Three TaARE1 homoeologs resulted in more active nitrate transport than ammonium transport upon N deprivation, and the different TaARE1 homoeologs have diverged in this function.
• We isolated and characterized three TaARE1 homeologs in an elite Chinese winter wheat cv ZhengMai 7698 and then generated a series of transgene-free mutant lines either with partial or triple null taare1 alleles through CRISPR/Cas9-mediated targeted mutagenesis of TaARE1.
• All transgene-free mutant lines (TaARE1) showed enhanced tolerance to nitrogen starvation, and delayed senescence and increased grain yield in a field experiment.
