Panels a-i represent time-course profiles for PAO2, PAO4, AO1, AO2, AO3, AO4, AO5, ALDH10A9 and ALDH10A8, 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 wk represents the least significant difference at the P ≤ 0.05 level. Note that the y-axis varies among the panels. AO Amine Oxidase, ALDH aldehyde dehydrogenase, PAO polyamine oxidase
