Stomatal Function and Evolution

Our research focuses on how the function of stomata has changed through time using living lycophytes, ferns, conifers and angiosperms to reconstruct the history of stomatal physiology. Profound changes in the way stomata behave suggest that stomata functioned as passive hydraulic valves in early vascular plants, but that chemical signalling became increasingly important during the evolution of conifers and angiosperms. We argue that his evolutionary trajectory has heavily impacted the evolution and ecology of the major plant groups.
