C6.1 | C4-GRASSES IN WEST AFRICA: EVOLUTION, RANGE SHIFTS AND PHYSIOLOGY UNDER CLIMATE CHANGE AND ALTERED LAND USE
In this project the genus Panicum serves as a model system including economically important species (e.g. Panicum laetum as a crop and pasture grass). In selected Panicum species of the three different types of C4 photosynthesis (NADP-ME, NAD-ME and PCK-type), the biochemical properties of the C4 key enzyme PEPC and the corresponding genomic sequences including the regulatory regions are determined. Experiments under drought stress provide data on the efficiency of the enzyme under conditions of water shortage. The molecular data will also yield insight into the evolution of the three different metabolic types of photosynthesis within the genus.
