Panels a-i represent time-course profiles for GAD1, GAD2, GAD3, GABA-T1,2, GLYR1, GLYR2, SSADH1, SSADH2 and ALA-T, respectively. Storage conditions: 0 °C, 2.5 kPa O2 and 5 kPa (●) or 0.03 kPa (○) CO2. All the data represent the mean of three treatment replicates, each being the average of three subsamples. The error bar above 0 weeks represents the least significant difference at the P ≤ 0.05 level. Note that the y-axis varies among the panels. ALA-T alanine dehydrogenase, GABA-T GABA transaminase, GAD glutamate decarboxylase, GLYR glyoxylate reductase, SSADH succinic semialdehyde dehydrogenase
