In the light of stomatal opening: new insights into ‘the Watergate’

Roelfsema, M. Rob G., Hedrich, Rainer·2005·New Phytologist

Abstract

Summary: Stomata can be regarded as hydraulically driven valves in the leaf surface, which open to allow CO 2 uptake and close to prevent excessive loss of water. Movement of these ‘Watergates’ is regulated by environmental conditions, such as light, CO 2 and humidity. Guard cells can sense environmental conditions and function as motor cells within the stomatal complex. Stomatal movement results from the transport of K+salts across the guard cell membranes. In this review, we discuss the biophysical principles and mechanisms of stomatal movement and relate these to ion transport at the plasma membrane and vacuolar membrane. Studies with isolated guard cells, combined with recordings on single guard cells in intact plants, revealed that light stimulates stomatal opening via blue light‐specific and photosynthetic‐active radiation‐dependent pathways. In addition, guard cells sense changes in air humidity and the water status of distant tissues via the stress hormone abscisic acid (ABA). Guard cells thus provide an excellent system to study cross‐talk, as multiple signaling pathways induce both short‐ and long‐term responses in these sensory cells.ContentsSummary665I.Introduction665II.The hydrodynamic valve666III.Regulation of ion transport in guard cells678IV.Interaction between guard cell signaling pathways682V.Outlook684Acknowledgements685References685

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
