Feb 25, 2025 · The Arabidopsis GORK channel is a major pathway for guard cell K+ efflux that facilitates stomatal closure.

Oct 20, 2022 · Here we show that clustering of the GORK channel, which mediates K + efflux for stomatal closure in the model plant Arabidopsis, arises from binding between the channel …

A K + channel from the C4 plant Gynandropsis gynandra accelerates stomatal kinetics, thereby enhancing biomass gains and water use efficiency when expressed in the C3 model …

Stomata are the major gates in plant leaf that allow water and gas exchange, which is essential for plant transpiration and photosynthesis. Stomatal movement is mainly controlled by the ion …

Jan 19, 2025 · Potassium ions (K+) play a crucial role in regulating the opening and closing of stomata, which are tiny pores on plant leaves that facilitate gas exchange. According to the …

Stomatal pores, each surrounded by a pair of guard cells, regulate CO2 uptake and water loss from leaves. Stomatal opening is driven by the accumulation of K+ salts and sugars in guard …

The four important theories of stomatal movement are: (1) Theory of Photosynthesis in Guard Cells (2) Starch Sugar Inter-conversion Theory (3) Theory of Glycolate Metabolism and (4) …

Jun 18, 2013 · Stomata open in response to light and close after exposure to abscisic acid (ABA). They regulate gas exchange between plants and the atmosphere, enabling plants to adapt to …

Sep 1, 1997 · Here, two classes of Kchannels - which differ in their voltage dependencies, agonist and antagonist sensitivity, and their gating kinetics - dominate the K+ conductance of the …

Nov 27, 2023 · Electrophysiological analysis of the dominant K + channels showed that the outward‐rectifying channels, responsible for K + loss during stomatal closing, were …
