AN important aspect of the stomatal mechanism in green plants is the transport of solutes into and out of guard cells in response to stimuli such as illumination1. The effect of abscisic acid (ABA) in causing stomata to close has been ascribed to ABA-promoted solute leakage from guard cells 2. The experiments reported here show that leakage alone is insufficient to explain stomatal closure caused by ABA. The involvement of live epidermal cells, acting as recipients of solutes from guard cells, is necessary, as Penny and Bowling have suggested, especially when considering intact leaves3.
