Many of our own studies have emanated from the investigation of amyloplasts, the organelles in which starch is made. We are attempting to elucidate the biochemical mechanisms which serve to regulate the enzymes of starch synthesis within amyloplasts. We are actively investigating the role of post-translational modification (protein phosphorylation) and were the first to demonstrate the existence of multi-enzyme complexes which are involved in making starch. The techniques we use to address these questions include proteomic technologies such as mass spectrometry, and bioinformatics as well as protein isolation and organelle purification coupled with genetic modification. Our research covers cereals such as maize, barley, rice, and wheat, as well as the model organism Arabidopsis thaliana. Genetic manipulation of starch biosynthesis in the latter has led us into an exciting new project aimed at improving oilseed production in crops such as canola.
