(Submitter supplied) In this study, we used GC-MS analysis in combination with flux analysis and the Affymetrix ATH1 GeneChip to survey the metabolome and transcriptome of Arabidopsis leaves in response to manipulation of the thiol-disulfide status. Feeding low concentrations of the sulfhydryl reagent dithiothreitol (DTT) for one hour at the end of the dark period led to post-translational redox-activation of ADP-glucose pyrophosphorylase and major alterations in leaf carbon partitioning, including an increased flux into major respiratory pathways, starch- cell-wall-, and amino-acid synthesis and a reduced flux to sucrose. more...

Analysis of leaves treated with dithiothreitol (DTT) for 1 hour. DTT is a sulfhydryl reagent that serves as a nonphysiological redox donor and substrate for thioredoxins. Results provide insight into the contribution of changes in transcripts levels to the regulation of metabolism by thioredoxin.
