Fig. 3From: Metabolome and transcriptome profiling provide insights into green apple peel reveals light- and UV-B-responsive pathway in anthocyanins accumulationKEGG pathway enrichment of metabolites under the dark (CK), visible light and UV-B radiation treatments. A-C KEGG pathway enrichment of metabolites under the dark (CK), visible light and UV-B radiation treatments. D Heat map of 58 selected metabolites. The phenylpropanoid pathway metabolites were the most significantly changed metabolites.
