Welcome to the Swanson Arabidopsis Research Lab



Do you mate randomly? How do you choose a mate? How do other animals choose mates? What about plants? Mate choice mechanisms have striking evolutionary significance in organisms across kingdoms, but in flowering plants, are less well understood. Indeed, because of their lack of mobility, flowering plants are sometimes thought to be passive and indiscriminate mates. Empirical studies have demonstrated this not to be so. In my lab, we exploit tools available in the model plant Arabidopsis thaliana to identify genetic architectures and discrete cellular behaviors that lead to nonrandom mating in plants. The long-term goal of my lab is to fully understand the genic underpinnings of nonrandom mating in plants.
