Fig. 6: Significantly enriched KEGG pathways of differentially expressed genes (DEGs) in pairwise comparisons at the P < 0.05 level.

The enrichment factor represents the ratio of the proportion of genes annotated to the pathway among DEGs to the proportion of genes annotated to the pathway among all genes. The number at the top of the vertical bars represents the number of DEGs enriched in the corresponding pathway. RB red–blue light, RBG red–blue–green light, RBW red–blue–white light, RBY red–blue–yellow light, W white light
