Stomatal movements control CO2 uptake for photosynthesis and water loss through
transpiration, and therefore play a key role in plant productivity and water use efﬁciency.
The predicted doubling of global water usage by 2030 mean that stomatal behaviour is central to current efforts to increase photosynthesis and crop yields, particularly under conditions of reduced water availability. In the ﬁeld, slow stomatal responses to dynamic environmental conditions add a temporal dimension to gaseous ﬂuxes between the leaf and atmosphere.
Here, we review recent work on the rapidity of stomatal responses and present some of the possible anatomical and biochemical mechanisms that inﬂuence the rapidity of stomatal movements.
