Quantitative Systems Biology
We focus on two major questions using plant natural chemistry as our model system. Plant natural chemistry generates compounds that provide the taste, flavor, color and medicinal activities that people associate with specific plants. However, their primary role appears to be helping the plant cope with its environment by attracting pollinators, repelling attackers and protecting the plant from sunlight. These aspects make these compounds easy to measure and key tools in understanding modern systems biology and genomics. The first question that we use these chemicals for is to understand how thousands of genes coordinate within a system to control the proper functioning of the system. This involved modern quantitative genomics and tools such as genome wide association mapping and QTL analysis. We are at the forefront of developing network analysis approaches and theory to help with the modern synthesis of the gene-to-phenotype linkage. The second question we focus on is why plants make these chemicals. They have broad activities and plants make an amazing diversity of chemicals, each potentially with its own function and evolutionary history. We are primarily using the model plant, Arabidopsis thaliana, to study how its secondary metabolites control interactions with both insects and fungi. As a part of this we are using a mixture of functional genetics, quantitative genetics, plant biology, evolutionary biology and metabolite profiling to develop as in depth and broad a picture as possible. To broaden this picture, we are expanding into rice, tomato, Lycopersicon, and grapes, Vitis. An additional avenue that we are pursuing is the fact that fungi also make secondary metabolites. For instance, Botrytis cinerea produces a suite of secondary metabolites whose main role appears to be killing plant cells. Thus by studying how Arabidopsis and Botrytis interact, we hope to analyze how organisms can combat each other through metabolism. We are expanding our quantitative systems approaches to study genetic variation in both the host and pathogen of this system simultaneously.
