Abstract excerpt

Reconciling the trade-off between short growth duration and high grain yield is essential for enhancing annual rice yields. We found that qTGW1a, encoding a flowering locus T-like protein, controls heading and nitrogen use efficiency (NUE) underpinning grain weight and yield in rice. TGW1a interacts with and stabilizes Ghd7 and Hd1 to boost NUE and grain yield. Natural variations in the promoter enable the...
