- A genetic module, NCR1, boosts grain yield and nitrogen use efficiency (NUE) in maize by improving nitrate transport.
- NCR1 encodes a MYB transcription factor that regulates the nitrate transporter NRT2.3, controlling nitrate translocation from roots to shoots.
- The superior NCR1-In allele has decreased in frequency with increased nitrogen fertilizer use in China.
- Overexpression of NCR1 or NRT2.3, or introgression of NCR1-In, increases grain yield and nitrogen content in shoots and seeds.
- This study identifies a crucial genetic module for enhancing agricultural sustainability by improving NUE and grain yield.
