Název v původním jazyce

Role of plant growth regulators in stomatal limitation to photosynthesis during water stress

Popis výsledku v původním jazyce

Although prolonged water stress can decrease Yleaf and close stomata via hydraulic influences, in many cases, plants use chemical signals travelling in the xylem to initiate stomatal closure thus preventing any decrease in Yleaf. Such signals can operateprior to any increase in bulk leaf hormone concentrations. Most interest has centred on ABA as the most probable root-to-shoot chemical signal regulating stomatal aperture. Apoplastic ABA concentration around the guard cells is crucial in determining stomatal responses, and this will depend on many factors including xylem ABA delivery to the leaf, leaf mesophyll ABA catabolism, leaf ABA synthesis and apoplastic pH. Even when apoplastic ABA concentration is constant, environmental and physiological variables such as CO2 concentration, temperature and current leaf water status can alter stomatal response to ABA. Other plant hormones are also important in modifying stomatal response to a given ABA concentration. The most probable candi...
