Figure 4.

The cluster of metabolites and energy Q values between Catharanthus roseus and Vinca minor. (a) Heat map visualization of relative differences of metabolites in C. roseus and V. minor. The content value of each metabolite was normalized to complete linkage hierarchical clustering. The metabolites were glycolic acid, threonic acid, threitol, anhydroglucitol, digalacturonic acid, galactonic acid, gentiobiose, octanal, sorbitol, itaconic acid, cellobiose, maleamate, methyl- galactopyranoside, glucopyranoside, glycocyamine, aminooxyacetic acid, loganin, threonine, threonine, glyceric acid, dihydroxybenzoic acid, tartaric acid, quinic acid, glucoheptonic acid, trehalose, hydroxybutyrate, lactitol, levoglucosan, gallic acid, ethanolamine, lyxose, aminobutyric acid, succinic acid, salicin, maltotriose, raffinose, saccharic acid, isoleucine, lucose-1-phosphate, hydroxypropionic acid, methionine, aminoisobutyric acid, serine, ornithine, dodecanol, methyl phosphate, erythrose, methoxytryptamine, mono phthalate, fucose, caffeic acid, xylitol, nicotinoylglycine, malic acid, citramalic acid, glycolic acid, pyruvic acid, allothreonine, aspartic acid, oxoproline, galactinol, chlorogenic acid, ribose, myo-inositol, tagatose, fructose, talose, mannitol, glucose, anhydrogalactose, phosphate, fumaric acid, gluconic lactone, dimethylsuccinic acid, glucose-6-phosphate, valine, tyrosine, amino-1-phenylethanol, glutamic acid, maleic acid, glutamine, isocitric acid, alpha-ketoglutaric acid, acetyl-glutamic acid, galactose, phytol, norleucine, oxalic acid, mannosylglycerate, glutaconic acid, alanine, lysine, lactic acid, methyl-amino-1,2-propanediol, glycerol, proline, hydroxynorvaline, from top to bottom, in turn. Red indicates high abundance, whereas low relative metabolites are green. V1, V2, V3, V4, V5, V6 indicate V. minor, C1, C2, C3, C4, C5, C6 indicate C. roseus; (b) The Q value of energy between Catharanthus roseus and Vinca minor.
