One of the fundamental characteristics of plant cells is that they are totipotent.  That is to say that, that each individual cell has the potential to regenerate into an entire plant.  This concept is the basis of vegetative plant propagation and a variety of approaches used in crop improvement with far reaching economic and cultural implications.  However, while plant cells are totipotent in theory, it is not possible to realize this potential in many plant species which are generally referred to as recalcitrant.  My primary research interest is to better understand why some plants are recalcitrant and to develop new approaches to establish integrated plant production systems.

Recent work has highlighted the importance of phenylpropanoid metabolism in plant morphogenesis, growth, and development in vitro.  While these compounds play an important role in the life of plants in the “real world”, they generally have a negative impact on plant growth and development in vitro.  My research is focussed on the manipulation of this pathway using selective biosynthetic inhibitors to better understand recalcitrance and develop new methods to manipulate these species.  This approach has facilitated the first protoplast to plant regeneration system in American elm, resulted in a novel approach to reduce oxidative browning in vitro, and has helped evaluate the functional role of phenylpropanoids in the Poaceae.  Ongoing research will apply this information to develop methods to conserve endangered plants, introduce novel vegetatively propagated crops, and develop tools for genetic improvement/breeding programs.
