The excess application of nitrogen fertilizer in agriculture and the limitation of nitrogen uptake by crops raise the alarm about the urgency to breed crops with higher nitrogen use efficiency (NUE). Recently, a novel strategy has been developed to enhance NUE and crop production by manipulating nitrate remobilization.

氮肥少，产量高。

氮肥在农业中的过量应用以及农作物对氮的吸收受到限制，使人们迫切需要培育出具有较高氮利用率（NUE）的农作物。最近，已开发出一种通过控制硝酸盐迁移来增强NUE和作物产量的新策略。
