3.5 Functional enrichment analysis
The KEGG analysis revealed that “Photosynthesis - antenna proteins”, “MAPK signaling pathway - plant”, “Glycine, serine and threonine metabolism”, “Plant hormone signal transduction” and some other pathways were significantly enriched following exposure to BL, WL, and RL (Fig. 5A-C). However, “Carotenoid biosynthesis” pathway was only enriched in BL, while “Flavonoid biosynthesis” pathway was minimally enriched in BL compared to WL and RL (Fig. 5A-C). Furthermore, “Anthocyanin biosynthesis” pathway was only enriched in RL, although it was not significant (Fig. S1).
