MetSO content of soluble proteins from isolated chloroplasts of plants after exposure to oxidative stress. A, Plants overexpressing PMSR4. B, Plants underexpressing PMSR4. MetSO content is expressed as the percent of MetSO in relation to the total Met pool (Met + MetSO). For details on the treatments, see “Materials and Methods.” sd is shown as an error bar and represents the average of three independent chloroplast preparations. In each section, means with the same letter above the bars are not statistically different (P ≤ 0.05).
