Research Group: Plant Ecophysiology
Plants display incredible plasticity in their response to a changing environment. Under different environmental stimuli, plants shift their resource allocation between general and specialized metabolism. The interaction between general and specialized metabolism affects for plant performance, and impacts digestibility and toxicity. With temperatures and atmospheric conditions changing at unprecedented rates, this interaction must be understood to improve crop performance, and conserve wildlife systems.
- Evolution, structure and function of plant YUCCA enzymes, and their specific role in mediating plant environmental stress resistance
- Pathway discovery of genes involved in general and specialized metabolism, with a focus on the role of cytochromes P450 and flavin containing monooxygenases
- Enzyme optimization by ancestral sequence reconstruction (ASR) for biotechnology
- Integrated “omics” approach to understand the role and regulation of specialized metabolites in trees and shrubs (e.g. Eucalyptus, Empetrum) in response to environmental stress
- Evolution of general and specialized metabolite pathways in ferns

Using a multi-disciplinary approach, our research has established an intricate interplay between plant general and specialized metabolism. We have demonstrated that plants exhibit a metabolic shift in chemistry in response to developmental and environmental change; in the glasshouse and in the field. The redirection of resources between general and specialized metabolism can improve plant growth and performance under adverse conditions. This metabolic shift, however, has significant consequences for plant toxicity and nutritional content, and downstream consequences on different trophic levels.
We have optimized analytical methods to separate and analyze complex plant mixtures. We are currently identifying key biosynthetic pathway members involved in the biosynthesis of different specialized metabolite classes, combining transcriptomic and proteomic analyses.
