From: Flux sampling is a powerful tool to study metabolism under changing environmental conditions
Flux sampling distributions of key reactions linking photosynthetic input (CO2) to transient carbon storage for control (red) and cold (blue) conditions. Condition-specific carbon assimilation and fumarate (FUM), malate (MAL), and starch accumulation were constrained according to experimentally measured results. Resulting fluxes of reactions including triose phosphate (TP), fructose 1,6-bisphosphate (F6P), glyceraldehyde 3-phosphate (G3P), pyruvate (PYR), arginosuccinate (AS), arginine (ARG), phosphoenolpyruvate carboxylase (PEP), oxaloacetate (OAA), γ-aminobutyric acid (GABA), acetyl coenzyme A (ACoA), and sucrose (Suc) are shown. We overlaid FBA results for maximum biomass production (under the same model constraints as applied for the sampling) as vertical blue and red bars over the flux sampling distributions. Reactions for which the two distributions are significantly different (p < 0.001; Kruskal–Wallis) are marked with an asterisk in the top right corner
