Journal ArticleDOI
The role of stomata in sensing and driving environmental change.
TL;DR: Stomatal morphology, distribution and behaviour respond to a spectrum of signals, from intracellular signalling to global climatic change, which results from a web of control systems reminiscent of a ‘scale-free’ network, whose untangling requires integrated approaches beyond those currently used.
Journal ArticleDOI
Abscisic acid-induced elevation of guard cell cytosolic Ca2+ precedes stomatal closure
TL;DR: It is reported that abscisic acid induces a rapid increase in guard cell cytosolic free Ca2+ in Commelina communisL, and that this increase precedes stomatal closure, which strongly support the sugá-gestion that Ca2- is an intracellular second messenger in this response.
Journal ArticleDOI
The vacuolar Ca2+-activated channel TPC1 regulates germination and stomatal movement.

TL;DR: A tpc1 knockout mutant lacks functional slow vacuolar channel activity and is defective in both abscisic acid-induced repression of germination and in the response of stomata to extracellular calcium, demonstrating a critical role of intracellular Ca2+-release channels in the physiological processes of plants.
Journal ArticleDOI
The generation of Ca(2+) signals in plants.
TL;DR: This work focuses particularly on the mechanisms responsible for generating [Ca(2+)]cyt oscillations and transients and uses Nod Factor signaling in legume root hairs and stimulus-response coupling in guard cells to assess the physiological significance of these classes of Ca(2+) signals.
Journal ArticleDOI
The stomatal response to reduced relative humidity requires guard cell-autonomous ABA synthesis.

TL;DR: It is shown that guard cells possess the entire ABA biosynthesis pathway and that it appears upregulated by positive feedback by ABA, highlighting the primacy of abscisic acid (ABA) in the stomatal response to drying air.
