Research advance on nitrogen uptake and utilization in rice and its relationships with root characteristics
The rice root system plays an important role in the nitrogen uptake and utilization.In this article,we introduced the process of nitrogen uptake and assimilation and root characteristics in rice,and sum-marized the effect of root characteristics on nitrogen absorption and the regulation of nitrogen supply on root characteristics.The further research directions were discussed in terms of nitrogen uptake and utili-zation,root characteristics and nitrogen fertilizer interaction.This review may provide theoretical consider-ation for improving nitrogen uptake and utilization efficiency,and provide new insights for developing rice cultivars with high nitrogen efficiency.
