Research Interests

World wheat productivity is approaching 700 million tonnes, and faced with the perfect storm of climate change and a burgeoning population, the goal of increasing wheat yields sustainably is pre-eminent. It is recognized that a new green revolution will  need to include both traditional and modern technologies.

One way to enhance photosynthesis is to improve the diffusive supply of the substrate CO2, which is controlled by conductances into the leaf (via stomata, Gs), and then through tissues and cells (as mesophyll conductance, Gm). One mechanism enhancing gm, which is currently attracting attention, is the role of specific CO2 channels (aquaporins and carbonic anhydrases) in cell membranes, which facilitate the transfer of CO2 from airspaces to chloroplast.  Another area is the extent that the kinetic properties of the primary carboxylase, Rubisco, could be manipulated to increase selectivity for CO2 over oxygen,and thereby reduce photorespiratory losses.

The aim of my project is to screen the extent of natural variability in Gmes in a range of wheat varieties. Then, a genetic approach will be used to over express the genes that enhance CO2 supply and to explore the impact of enhanced CO2 pore activity on enhancing Gm and photosynthetic capacity.
