Research

Stomata are pores that open to allow carbon dioxide into leaves for photosynthesis and close to reduce water loss. Stomata are important because their behaviour affects crop productivity, and global carbon and water cycles. We study how stomatal aperture and stomatal development are controlled by the plant, and how environmental change affects both the number of stomata that are produced and their sensitivity. We use molecular genetic techniques to study the evolution of stomatal signalling pathways which are believed to have been important for the greening of the earth over 400 million years ago. Recently we have begun to translate our finding into important crops including wheat and rice, to improve drought tolerance and water use efficiency.

Right: Thermal imaging is used to assess stomatal responses. Plants with more open stomata are depicted as pink/blue. They lose more water and are cooler.
