The mechanics of stomatal movements,tal 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 poly

The theory of gas diffusion through stomata,resistance to diffusion (e.g. Brown and Escombe, 1900) to the development of complex models and theory (see, e.g. Penman and Schofield, 1951; Monteith, 1983). Although the general concepts are now well established (see, e.g. Weyers and Meidner, 1990; Nobel, 1991; Jones, 1992) some controversial aspe

Stomatal responses to environmental factors,ts environment. Furthermore, guard cells are usually only connected to neighbouring cells via their dorsal walls, and, at maturity, these walls do not possess functional plasmodesmata (see Chapter 3). Thus, because of their relative isolation from the rest of the plant body, stomata are ideally suit

The influence of hormones and other naturally occurring compounds on stomatal behaviour,lved in the control of stomata. Additionally, many other naturally occurring compounds affect stomata including certain fatty acids, some phenolics, simpler metabolites, such as proline, and many Phytotoxins, such as fusicoccin and victorin, which are produced by fungal pathogens.

Ionic relations of stomatal movement and signal transduction in guard cells,ve proved inadequate to a greater or lesser degree. Since the late 1960S, however, major advances in our understanding of how stom- ata function have been made with the application of diverse and new technologies, such as electrophysiology and ion imaging. It is now clear that ion accumulation forms

Recent developments and future research,e. It should be apparent by now that guard cells are highly specialized cells and they have adopted an array of cellular and meta- bolic processes which enable stomata to be exquisitely tuned to the environment and the demands within the plant. Stomata can be viewed as one of the major adaptations t
