- OsWRI1a regulates rice growth responses to nitrogen availability.
- It stabilizes the root-to-shoot ratio by coordinating root and shoot development.
- In roots, OsWRI1a promotes auxin accumulation for N-responsive growth.
- In shoots, it stimulates tiller development to enhance shoot growth.
- An elite OsWRI1a haplotype minimizes root-to-shoot ratio fluctuations under N deficiency.
- This improves nitrogen-use efficiency and grain yield.
- The findings support sustainable agriculture by optimizing N-responsive growth allocation.
