Redox and allosteric properties of AGPase and endogenous ADP-Glc content in 35 DAF tomato fruits of NTRC-RNAi lines 2, 26, and 33 compared to the wild type (WT). A, Redox state of the intermolecular disulfide bond in APS1. B, AGPase activity assayed with or without the activation of 10 mm 3-PGA. C, AGPase activity kinetics in the presence of varied concentration of 3-PGA as indicated in the figure. D, Content of endogenous ADP-Glc. The monomer-to-dimer ratios of the respective proteins were quantified by Image-J software. Results are the mean ± se (n = 5–6). Statistical analysis used ANOVA with Dunnett’s test (*P < 0.05, compared to the wild type). FW, fresh weight
