Project Goals:..............Development of mathematical models to test and advance our knowledge of how metabolism is regulated in plants
Mathematical model can serve to gain fundamental insights of how flux is distributed between metabolic pathways. Depending on the complexity of the problem and availability of appropriate data, different approaches can be taken. Genome-scale models are based on balancing the reactions of an entire network, where various data sets can be incorporated as constraints for calculations. The scope of kinetic models tends to be more focused and they require detailed information on the biochemical properties of all enzymes. We are integrating mathematic modeling in iterative processes to simulate the biochemistry of a particulr biosolgical system of interest and performing experiments to capture pathway regulation at all levels. These approaches have empowered metabolic enigneering and molecular breeding efforts, often with an emphasis on enhancing the accumulation of metabolites in specialized cell types and tissues.
