Integrated metabolomic and transcriptomic analysis of the MEP pathway. a Overview of the MEP pathway. The orange backgrounds indicated the genes identified by the transcriptome and red font indicated the metabolites identified by the metabolome. b Differential expression of the key genes involved in the MEP pathway. The heatmap scale ranges from − 4 to + 4 on a log2 scale. c Differential accumulation of the intermediate metabolites involved in the MEP pathway. “*” represents significant differences (P < 0.05)
