Welcome to the Frank Lab!

We study the biology of plant grafting. Although grafting has been used as a tool to improve plant performance for over 2,000 years, there are many open questions about what makes particular graft combinations successful, how graft junctions are formed, and what moves between grafted organ systems. We use genetics, genomics, and phenomics to explore these questions. Our longterm aim is to be able to identify successful graft combinations in a predictive manner, and to engineer graft donor genotypes that provide sustainable solutions for crop protection in the face of biotic and abiotic pressures.
