Fig. 7: Model for the induction and subcellular localization of enzymes associated with GABA and GHB metabolism in ‘Empire’ apple fruit stored under low temperature, low O2 and elevated CO2 conditions.
Bold blue lettering represents known biochemically characterized enzymes, whereas bold white lettering and dashed arrows represent putative polyamine oxidases, which were localized to the peroxisome using in silico comparisons with Arabidopsis orthologs (see Supplementary Information Fig. S1). 4-ABAL 4-aminobutanal, DAP 1,3-diaminopropane, SSA succinic semialdehyde, TCA tricarboxylic acid. For other abbreviations, see Fig. 6
