Abstract

The aim of the work is to examine the role of the triose- phosphate translocator (TPT) in coordinating cytosolic and chloroplastic metabolism, and to elucidate the contribution of sugar-sensing to photosynthetic gene regulation. Photosynthetic activities will be examined in a range of Arabidopsis mutants devoid of TPT under different environmental conditions. The metabolic and photochemical effects of replacing TPT by translocators with altered specific will be examined. Mutants with altered photoassimilate metabolism will be used to determine the effect of sugar-sensing on light acclimation and the redox poise of chloroplasts components. Comparison of changes in the transcriptome of wildtype and TPT mutant in response to changes in light intensity will be used to identify genes associated with light acclimation.
