Main characteristics of bna572 with standard biomass composition (w/w). A, The main subcellular compartments, exchange with the environment, fixed flux rates, and the synthesis of biomass from eight biomass compounds. The biomass flux is fixed to the growth rate of a rapeseed embryo after 10 d in culture (Hay and Schwender, 2011b). Flux states are predicted based on the minimization of exchange reactions (indicated substrate uptakes) and constant proportions of biomass constituents. B, Biomass composition of a cultured embryo (standard biomass composition). Different tradeoffs between TAG and protein were simulated by varying the proportions of protein and TAG, while the sum of protein and TAG and the fractions of all other biomass components were kept constant. C, Cytosol; CW_ap, cellulose; lu, plastid thylakoid lumen; m, mitochondrial matrix; P, plastid stroma; Prot_c, protein; Sucr_c, Suc; X, peroxisome.
