Gene-metabolite map of the GABA and lactic acid pathways in florets from packed cultivars. Differential gene expressions (squares) and differential compound abundances (circles) in Olter and BAT39 cultivars from two production cycles are highlighted by heatmaps according to log2 fold change (log2FC) with respect to harvested products. Arginine pathway: ADC, arginine decarboxylase; AGD, agmatine deiminase; ALDH, aldehyde dehydrogenase (NAD+); CPA, N-carbamoylputrescine amidase; PAO, polyamine oxidase; SPDS, spermidine synthase. Glutamate pathway: GAD, glutamate decarboxylase; GDH, glutamate dehydrogenase [NAD(P)+]; GOGAT, glutamate synthase (NADH); GS, glutamine synthetase; NAD-GDH, glutamate dehydrogenase (NADP+). Pyruvate route: ASN, asparagine synthase; ASNase, asparaginase; AST, aspartate transaminase; GGAT, glutamate—glyoxylate aminotransferase 1; LASPO, L-aspartate oxidase; LDH, L-lactate dehydrogenase; PDC, pyruvate decarboxylase; PK, pyruvate kinase. TCA cycle: ACLA, ATP citrate synthase; ACO, aconitate hydratase; CSY, citrate (Si)-synthase; FH, fumarate hydratase; GABA-T, 4-aminobutyrate—pyruvate transaminase; GLYR, glyoxylate reductase (NADP+); ICL, isocitrate lyase; IDH, isocitrate dehydrogenase; LSC, succinyl-CoA synthetase; MDH, malate dehydrogenase; MS, malate synthase; SDH, succinate dehydrogenase; SSADH, succinate-semialdehyde dehydrogenase (NAD+). GABA transporters: AAP3, amino acid permease 3; ALMTs, aluminium-activated malate transporters; BAT1, bidirectional amino acid transporter 1; GAT1, GABA transporter 1; ProT2, proline transporters 2.
