Stomatal movements depend on the transport and metabolism of osmotic solutes that drive reversible changes in guard cell volume and turgor. These processes are defined by a deep knowledge of the identities of the key transporters, their biophysical and regulatory properties, and have been modelled successfully with quantitative kinetic detail at the cellular level. Transpiration of the leaf and canopy, by contrast, is described by quasi-linear, empirical relations relating inputs relevant to photosynthesis, but without connection to guard cell mechanics. I introduce a quantitative systems platform bridges this micro-macro divide and offers a powerful tool with which to explore the links between guard cell homeostasis, stomatal dynamics and foliar transpiration.
