Differential gene expression in maize kernels exposed to different light environments. A Numbers of differentially expressed genes (DEGs) under various light conditions. B Up- and downregulated DEGs under various light conditions. C UpSet plot for DEGs under various light conditions. D Biological processes and (E) molecular functions associated with DEGs according to Gene Ontology (GO) enrichment analysis. Significance criteria: log2|fold change (FC)|> 1.5, false discovery rate (FDR) < 0.05, P < 0.05
