Aquaporins Contribute to ABA-Triggered Stomatal Closure through OST1-Mediated Phosphorylation.

The Plant cell - 1 Jul 2015

Abstract excerpt

Stomatal movements in response to environmental stimuli critically control the plant water status. Although these movements are governed by osmotically driven changes in guard cell volume, the role of membrane water channels (aquaporins) has remained hypothetical. Assays in epidermal peels showed that knockout Arabidopsis thaliana plants lacking the Plasma membrane Intrinsic Protein 2;1 (PIP2;1) aquaporin have a...
