Multivariate analysis of the metabolomic data derived from four groups of leaves of C. reticulata Blanco, cv. Hongjü. a PCA 3D plot of four groups of samples based on metabolomics data. b The PLS-DA score plot of metabolomics data of the CTV-infected and healthy ‘Hongjü’ leaf samples. c The cluster heatmap of the total metabolites of the four groups of samples. d Venn diagram of differential metabolites produced by CTV, CLas, and both pathogens in ‘Hongjü’. Health, HLB, CTV, and CTV + HLB indicate healthy, CLas infected, CTV infected, and CTV-CLas coinfected plants, respectively
