Project

Rewiring lignin biosynthesis

Research Interests

Lignin is a complex polyphenolic constituent of the secondary cell walls of vascular plants. It is important for structural support, water conduction and plant defence, and it accounts for roughly 18-35 % of woody biomass. But lignin poses a major challenge for industrial processing, particularly in the pulp and paper and biofuels industries. Through genetic engineering, it is possible to produce experimental plants with altered lignin content, composition and structure. My research aims to explore alternative approaches in the area of lignin engineering. In particular, I am developing new strategies to control the metabolic flux through the shikimate pathway which allocates carbon invested from photosynthate into the production of lignin and other phenylpropanoids. I am also exploring new avenues in the area of designer lignins with a goal towards reducing lignin recalcitrance and improving biomass utilisation efficiency.
