Unlocking the potential of DULL NITROGEN RESPONSE 1 for climate-smart crop breeding under elevated CO2.

This commentary highlights the role of DULL NITROGEN RESPONSE 1 (DNR1) in improving crops under changing climates. By understanding how DNR1 affects rice growth, the study paves the way for developing climate-resilient crop varieties (e.g., rice, wheat, and maize), potentially boosting yields and ensuring food security under elevated CO2 levels.
