Gene Details:

• Gene ID: Glyma.17g192000
• Gene Symbol: GmAAP6a
• Gene Name: amino acid permease 6
• Genome: Wm82.a4.v1
• Species: Glycine max

Functional Descriptions:

• Overexpression of GmAAP6a enhances tolerance to low nitrogen and improves seed nitrogen status by optimizing amino acid partitioning in soybean.
• Amino acid permeases (AAPs) play essential roles in amino acid transport between plant cells and subsequent phloem or seed loading. In this study, a soybean AAP gene, annotated as GmAAP6a, was cloned and demonstrated to be significantly induced by nitrogen starvation.
• Growth and transport studies using toxic amino acid analogs or single amino acids as a sole nitrogen source suggest that GmAAP6a can selectively absorb and transport neutral and acidic amino acids.
• Overexpression of GmAAP6a in Arabidopsis and soybean resulted in elevated tolerance to nitrogen limitation.
• Our results imply that overexpression of GmAAP6a enhances nitrogen stress tolerance and source-to-sink transport and improves seed quality in soybean.
