In addition to the ion channels in the plasma membrane, vacuolar ion channels have important functions in regulation of stomatal opening and closure because vacuoles can occupy up to 90% of guard cell’s volume. Therefore, a majority of ions are released from vacuoles when stomata are closed. Vascuolar K (VK) channels and fast vacuolar channels can mediate K release from vacuoles. Vacuolar K (VK) channels are …

WebAccording to this theory opening and closing of the stomata is due to the intake and loss of potassium ion .The opening of stomata is induced by light and accompanied by transport of potassium ion from surrounding epidermal cells to guard cell so opening of stomata is an active process where energy is required but closure of stomata is not. Webof K+ has been observed in kidney and brain mitochondria (4,5). More recent experiments made with the antibiotic valinomycin have also yielded contradictory results. Hijfer and Pressman (6) reported that K+ had marked effects on oxidative phosphoryl- ation on intact mitochondria, while Smith and Beyer (7), by
