Abstract
Considerable progress has been made in understanding the osmotic changes that generate turgor increases in a guard cell. However, despite the fundamental importance of mechanical interactions between guard cells and neighbouring cells in determining stomatal aperture, much still remains to be elucidated; there is little detailed information on the rele- vant cell volumes, on wall morphology or on the physico-chemical prop- erties of the wall polymers that translate turgor differences to changes in cell shape during stomatal movements. This chapter deals primarily with the water relations of guard cells and epidermal tissue, and the different modes of deformation of guard cells during stomatal movements. Additionally, the osmotic relations of guard cell protoplasts (GCPs) will be considered, including the dynamics of membrane recycling.
