OsDUF1223 negatively regulates seedling drought tolerance and modulates nitrate-dependent root growth in rice.
OsDUF1223 negatively impacts drought tolerance and nitrate-dependent root growth in rice seedlings, reducing survival rates under drought stress.
- Why it matters: Drought stress severely hampers rice production, and understanding key regulatory proteins can help develop more resilient crops. The roles of DUF-containing proteins in stress responses are not well understood, creating a knowledge gap in plant stress regulation mechanisms.
- What they did: Researchers overexpressed OsDUF1223 in rice and conducted transcriptomic and physiological analyses to investigate its function, focusing on drought response and nitrogen signaling pathways.
- The result: Overexpression of OsDUF1223 decreased drought survival, water retention, antioxidant activity, and osmolyte levels, revealing its role as a negative regulator and offering a target for improving drought tolerance in rice.
