Model for miRNAs and their target genes associated with grain development and the response to N levels. The black letters in green circles indicate miRNAs, and the red letters in black boxes indicate the target gene function. The black arrows represent the direction of regulation. TF, transcription factor; CRF, cytokinin response factor; SCF, Skp-cullin-F-box; GLU, glucosyltransferase; BRI, brassinosteroid insensitive; ASR, alternative splicing regulator; LRR-RPK, leucine-rich-repeat receptor-like protein kinase; K1P-PSS1, kinesin-1-like protein PSS1; ARF, auxin response factor; HNT, high-affinity nitrate transport; Redox, reduction-oxidation; HSP, heat-shock protein; POD, peroxidase
