Abstract

CP12 has been shown to form a regulatory complex with the Calvin cycle enzymes, glyceraldehyde-3-phosphate dehydrogenase and ribulose-5-phosphate kinase in vitro. Antisense transgenic tobacco plants will be used to investigate the in vivo role of CP12 in the regulation of photosynthetic carbon assimilation and on partitioning of carbon to sucrose, starch and secondary products. The effect of reductions in CP12 protein on complex formation and NADP-GAPDH and PRKase activity and regulation will be quantified during light/dark transitions. To address the impact of perturbations in the regulation of these Calvin cycle enzymes on carbon assimilation, the response of photosynthesis to changes in light intensity and CO2 concentration and during light induction will be measured. Photosynthetic and non-photosynthetic carbon fluxes will be determined using 14C feeding. Changes in primary and secondary metabolic products will be measured using freeze clamp techniques and LC-Tof-MS analysis. (Joint with grant number 19404).
