Organic acid levels in red ripe stage transgenic tomato fruits. A, Citric acid content. B, Malic acid content. C, Ascorbic acid content. Numbers are representative of the individual E8.2-OXDC lines, whereas the wild type corresponds to an untransformed plant. Data represent the values obtained from the means (± sd) of four plants, with two fruits per plant for each independent transgenic event and the wild type in triplicate represented by error bars. Asterisks indicate significant difference (P < 0.05) analyzed by Wilcoxon rank sum test.
