Rice is one of the most important cereal crops in the world, and a substantial increase in grain yield is necessary for food security. However, high yields of semidwarf modern rice varieties are heavily dependent on the application of mineral nitrogenous fertilizer (Tilman et al., 2002;Sun et al., 2014). nitrogen (n)-insensitive sponses associated with reduced n-use efficiency (nUE) is a major characteristic of the green revolution varieties (GRVs), in which the growth-inhibiting protein SLEnDER RICE1 (SLR1) accumulates (Li et al., 2018). Unfortunately, increasing the level of n fertilizer use to reach the full yield potential of GRVs is subject to diminishing returns, quite apart from its deleterious effect on the environments (Rahn et al., 2009;Liu et al., 2015). Therefore, there is an urgent need to develop new rice GRVs that increase nUE while maintaining their high yields. Recently, several genes (e.g., DEP1, ***, OsnRT2.3b, ARE1 and GRF4) responsible for improved nUE have been identified in rice (Sun et al.. 2014;Hu et al., 2015;Fan et al., 2016;Wang et al., 2018;Li et al., 2018). More importantly, boosting the activity of the transcription factor GRF4 overcomes the ability of SLR1 to prevent the GRF4-GIF1 interaction, which in turn promotes the coordinated expression of the genes involved in n assimilation and carbon fixation and consequently enhances the nUE of rice GRVs, thereby improving our ability to grow crops sustainably (Li et al., 2018). However, current understanding of the genetic basis for improving nUE remains at the level of identification of a number of quantitative trait loci (QTLs), without any understanding of the nature of the gene products.
