Research Interests

Plant cell biology

We are interested in cell walls, cell surfaces, cell expansion and cell adhesion. The construction and retention of rigid, polysaccharide-based cell walls by plant cells has significant implications for the mechanisms of cell proliferation, cell adhesion, cell development and growth. Multifunctional primary and secondary cell walls are important determinants of the mechanical properties of plant cells and organs. This makes cell walls of considerable interest and importance for fundamental plant biology. In addition cell walls are important materials in relation to the exploitation of plants for foods, textile fibres, polymers and increasingly as sustainable resources for bioenergy.

Cell walls are fibrous composites consisting of cellulose microfibrils embedded in a matrix of other polysaccharides and proteins. At Leeds we are generating and using sets of molecular probes for cell wall imaging to explore all aspects of plant cell wall biology. Our cell biological work involving the preparation and use of monoclonal antibody and carbohydrate-binding module probes is integrated with microscopy procedures and directed at a range of plant systems. Understanding how specific configurations of cell wall polysaccharides function in relation to developmental processes and the generation of mechanical properties are our major aims.
