Plant genetic networks – from databases to computational modeling
Functional Genomics
Using a systems biology approach, we are modeling biochemical pathways and regulatory processes that affect plant function and development. Among the central biochemical pathways in plants, isoprenoid synthesis produces key molecules for cellular function and metabolites of pharmacological interest. Genetic or biochemical disruption of pathway flux triggers changes in gene expression and metabolite end products. We are linking databases to explore the interdependence of biochemical pathway information and regulatory networks. A similar approach is applied to cell cycle regulation, which is the basis for developmental and differentiation processes.
The complete analysis of the chloroplast proteome is at the frontiers of understanding the organelle as a functional system. Exploiting advanced technologies and computing algorithms, we are discovering many novel proteins. Their genetic characterization will provide important new information on chloroplast pathways. The combined knowledge from systems approaches will allow us to model and predict plant functions.
