Nitric Oxide as a Mediator of Aba Signalling in Stomatal Guard Cells
Water shortage is likely to be one of the major global environmental stresses of the 21st century. A key plant response to declining soil water potential is increased biosynthesis and subsequent action of abscisic acid (ABA). ABA is an endogenous anti-transpirant that induces stomatal closure, thereby leading to water conservation. The signal transduction processes commencing with guard cell AB...
متن کاملThe Histidine Kinase AHK5 Integrates Endogenous and Environmental Signals in Arabidopsis Guard Cells
BACKGROUND Stomatal guard cells monitor and respond to environmental and endogenous signals such that the stomatal aperture is continually optimised for water use efficiency. A key signalling molecule produced in guard cells in response to plant hormones, light, carbon dioxide and pathogen-derived signals is hydrogen peroxide (H(2)O(2)). The mechanisms by which H(2)O(2) integrates multiple sign...
متن کاملNitric oxide in guard cells as an important secondary messenger during stomatal closure
The modulation of guard cell function is the basis of stomatal closure, essential for optimizing water use and CO2 uptake by leaves. Nitric oxide (NO) in guard cells plays a very important role as a secondary messenger during stomatal closure induced by effectors, including hormones. For example, exposure to abscisic acid (ABA) triggers a marked increase in NO of guard cells, well before stomat...
متن کاملABA, hydrogen peroxide and nitric oxide signalling in stomatal guard cells.
Increased synthesis and redistribution of the phytohormone abscisic acid (ABA) in response to water deficit stress initiates an intricate network of signalling pathways in guard cells leading to stomatal closure. Despite the large number of ABA signalling intermediates that are known in guard cells, new discoveries are still being made. Recently, the reactive oxygen species hydrogen peroxide (H...
متن کاملA new role for an old enzyme: nitrate reductase-mediated nitric oxide generation is required for abscisic acid-induced stomatal closure in Arabidopsis thaliana.
The plant hormone abscisic acid (ABA), synthesized in response to water-deficit stress, induces stomatal closure via activation of complex signaling cascades. Recent work has established that nitric oxide (NO) is a key signaling molecule mediating ABA-induced stomatal closure. However, the biosynthetic origin of NO in guard cells has not yet been resolved. Here, we provide pharmacological, phys...
