Figure 4

Schematic representation of metabolic pathways related to ABA production that were differentially regulated (p value < 0.05) between TBC-A and TBC-6 during the fermentation process.
The red arrows indicate upregulated pathways, blue arrows indicate downregulated pathways, and black arrows indicate pathways that were not significantly regulated. The most differentially regulated pathways are indicated by thick arrows. The biochemical pathways depicted are glycolysis, pentose phosphate pathway (PPP) and β-oxidation of fatty acids. Key metabolites such as cytosol acetyl-CoA, FPP and ABA are shown in bold red font. •Represents the putative mitochondrial carnitine carrier.
