Identifizierung und Analyse von Maismutanten mit Defekten im C 4-Zyklus
The C4-metabolism in Maize (Zea mays) serves to efficiently concentrate CO2 near the enzyme RuBisCo. Therefore the photorespiration, as we can find in C3-plants, is suppressed. Although numerous investigations deal with the regulation of the C4-photosynthesis, a lot of factors which take part in it …

Die epigenetische Regulation des C 4 -Syndroms : belichtungsabhängige Chromatinveränderungen am Promotor der Phosphoenolpyruvat Carboxylase aus Mais (Zea mays L.)
C4 plants have developed a unique mechanism to suppress the undesirable effects of photorespiration by separating primary and secondary CO2 fixation in two different leaf tissues. The primary fixation step takes place in the mesophyll cytoplasm and is controlled by phosphoenolpyruvate carboxylase …

Studies to influence the carbon metabolism of the C 3 plant Nicotiana tabacum by expressing heterologous enzymes involved in C 4 -like CO 2 fixation
… plant Nicotiana tabacum in order to establish a C4-like metabolic pathway ("C4-cycle"). These enzymes include phosphoenolpyruvate carboxylase (PC), NADP-malic enzyme (ME), pyruvate, orthophosphate dikinase (DK), phosphoenolpyruvate synthase (PS), phosphoenolpyruvate carboxykinase (CK) and …

Die C 4 -spezifische Phosphoenolpyruvatcarboxylase in Zea mays L.: Modellsystem zur Signaintegration auf Chromatinebene in Pflanzen
… act on the transcriptional activity of the C4-specific isoform of phosphoenolpyruvate carboxylase (C4-Pepc) and have to be integrated into a single promoter response. Therefore, C4-Pepc is a perfect candidate to investigate signal integration on the chromatin level. Previous studies in our …

Einfluss von Histonmodifikationen auf die gewebespezifische Transkription C 4-spezifischer Gene in Mais (Zea mays)
The regulation of C4-specific genes is influenced by many internal and external stimuli that are easily manipulated. Thus, C4-genes are good candidates to investigate signal integration on the chromatin level. Recent studies that focused on the C4-specific Pepc-gene revealed a complex promoter …
