Plant primary metabolism - From basic research to crop productivity
Plant Biochemistry
The domestication of crops was a landmark in the development of human civilisation. Today, most of our food and many of our resources are derived from plants. One of the most fundamental compounds is starch. Starch is the predominant storage carbohydrate in plants and the major constituent of our staple crops (e.g. rice, maize, wheat, potato etc). Despite its importance, our understanding of how plants make and degrade this essential resource is far from complete. Our research team focuses on the metabolic pathways leading to and from starch, and the way in which they are regulated.
We use the model plant Arabidopsis thaliana as our experimental system. This allows us to exploit the complete genome sequence and the array of post-genomic facilities to make rapid progress. Our current understanding suggests that different plants make starch is essentially the same way, as the components of the pathway appears to be highly conserved, even in distantly related species. Consequently, the knowledge gained through studying Arabidopsis will be transferable to starch-producing crops and enable their future improvement. This is an essential goal as the world population approaches its predicted peak of over 9 billion.
