Level changes of metabolites in the main metabolic pathways. Values in the boxes were ratios of peak intensity of metabolites in A. germari infected samples to those in mock-infected samples. Colors of red and green represented elevated and decreased levels of a metabolite in A. germari infected samples compared with mock-infected samples, respectively. Extended metabolites were marked with gray color. α-KG, alpha-ketoglutarate; CitA, citrate; FatA C16:0, palmitic acid; FatA C18:2, linoleic acid; FatA C20:0, arachidic acid; FatA C24:0, lignoceric acid; Fru, fructose; Fru6P, fructose 6-phosphate; FumA, fumaric acid; Gal, galactose; Glc, glucose; Gluc, Gluconic acid; Glc6P, glucose-6-phosphate; Glu, glutamate; Gly, glycine; Gly3P, glycerol-3-phosphate; IsocitA, isocitric acid; Lac, lactic acid; MalA, malic acid; Myo-ino, Myo-inositol; PEP, phosphoenol-pyruvate; Phe, phenylalanine; Raf, raffinose; Ser, serine; Suc, sucrose; SucA, succinate; Tag, Tagatose; Tal, Talose. Solid and dashed arrows indicated single and multiple enzymatic conversions, respectively.
