Research: Molecular regulation of plant development - Using a combination of genetic, genomic and biochemical approaches, we are investigating the regulation of a wide range of developmental processes including wood formation, seed development, trichome development, and flowering time. All these processes are affected by the plant hormone ethylene and we aim to better understand how ethylene is involved, and how it interacts with other factors to control plant development.
