Research

Research Interests

My research focusses on a specialised mode of photosynthesis, crassulacean acid metabolism (CAM), which results in substantial (i.e. up to 5 fold) improvement in plant water-use efficiency compared to other modes of photosynthesis (i.e. C3 and C4).  Examples of CAM plants include pineapple, prickly pear cactus, some orchids and Agave (used for production of Tequila).

CAM permits the uptake of CO2 at night and has evolved in up to 7% of higher plants, primarily as an adaptation to water-limited habitats. The expression of CAM is readily modulated by the environment, and thus serves as a model system for establishing the functional significance of genes and enzymes that optimize physiological performance in arid, resource-limited habitats. The day/night separation of carboxylation processes in the photosynthetic cells of CAM plants, also poses fundamental questions in terms of metabolic control and circadian synchronization of metabolism.

The drivers of my research are to understand the molecular and metabolic basis of CAM in its various physiological manifestations and to use this information to exploit the potential of naturally evolved and engineered CAM for sustainable productivity in a warmer and drier world.
