Differential metabolites analysis in pollinated-pistils after knockdown of NtPPOs. (a) Volcano plots present differential metabolites in pollinated-pistils between NtPPO-RNAi lines and WT. (b) Bubble plots show the KEGG pathway enrichment of differential metabolites in pollinated-pistils between NtPPO-RNAi lines and WT. Red box indicates the difference of KEGG pathway between NtPPO-RNAi lines and WT is significant, P < 0.05. (c) Differential metabolites in the differential significant pathway. Metabolites are colored to represent changes in abundance in the NtPPO-RNAi lines relative to the WT: red indicates increased abundance and up-regulation; blue indicates decrease and down-regulation; black indicates no change. Quantitative values after metabolites represent fold change (NtPPO-RNAi lines/wild type). Dashed arrows represent multiple enzyme-catalyzed reactions. dAMP, Deoxyadenosine monophosphate; AMP, Adenosine 5’-monophosphate; IMP, Inosine monophosphate; GMP, Guanosine monophosphate
