The effect of nitrogen(N)fertilizer on the development of maize kernels has yet to be fully explored.MicroRNA-mRNA analyses could help advance our understanding of how kernels respond to N.This study analyzed the morphological,physiological,and transcriptomic changes in maize kernels under different N rates(0,100,200,and 300 kg ha-1).The result showed that increasing N application significantly increased maize grains'fresh and dry weight until N reached 200 kg ha-1.Higher levels of indole-3-acetic acid,cytokinin,gibberellin,and a lower level of ethylene were associated with increased N applications.We obtained 31 differentially expressed genes(DEGs)in hormone synthesis and transduction,and 9 DEGs were regulated by 14 differentially expressed microRNAs(DEMIs)in 26 pairs.The candidate DEGs and DEMIs provide valuable insight for manipulating grain filling under different N rates.
