| Research Abstract |
For rice production in the world, the major constraint is water stress. Specifically, we found that drought in upland and the fluctuation between dry and wet in rainfed lowland and irrigated field with water saving technology like AWD, respectively, is the stress factor that limits the crop productivity. We further showed that the developmental plasticity exhibited by root system plays the key role in plant adaptation to such water stress conditions.
