Starch contents during growth in 12:12 and 6:18 conditions in wild-type plants and plants expressing modified forms of AGPase. A, Comparison of the wild type (Col-0) and two transgenic lines expressing a constitutively redox activated form of AGPase (the adg1 mutant transformed with a pAPS1::APS1C81S construct). B, Comparison of the wild type (Col-0), the adg1 mutant lacking the small subunit of AGPase, and a mutant lacking the APL1 large subunit of AGPase (adg2). See Supplemental Table S1 for calculated rates of starch synthesis. White and black bars are starch contents at the end of the night and after 6 h of the light period, respectively, in 12:12 conditions. Light-gray and dark-gray bars are starch contents at the end of the night and after 6 h of the light period, respectively, in 6:18 conditions. Values are means ± se of measurements made on six rosettes. FW, Fresh weight.
