Expression patterns of Chilo suppressalis-induced genes and metabolites involved in the metabolism of amines and polyamines and amino acids from the glutamate and aspartate family. a Pathway schematic of amino acid metabolism. Uppercase letters are genes that encoded enzymes. Metabolites shaded in green were measured. Solid arrows represent established biosynthesis steps, while broken arrows indicate the involvement of multiple enzymatic reactions. GDH, glutamate dehydrogenase; GAD, glutamate decarboxylase; GS, glutamate synthase; ODC, ornithine decarboxylase; PAO, polyamine oxidase; CPA, N-carbamoylputrescine amidase; ASL, adenylosuccinate lyase; ADH, aldehyde dehydrogenase; LASPO, L-aspartate oxidase; and P5CS, delta-1-pyrroline-5-carboxylate synthetase. GABA, gamma-Aminobutyric acid; GGS, L-glutamate gamma-semialdehyde. b Heatmap of relative expression levels of the genes involved in the schematic pathway. The heatmap was generated from the RPKM data using MeV (V4.9.0). c Metabolite abundance after C. suppressalis infestation; values are means ± SE (n = 10). *, P < 0.05 by Dunnett’s test relative to uninfested controls
