Vacuoles, the storage organelles of plants, can constitute up to 90% of the cell volume.
Transport of solutes such as sugars and organic and inorganic ions across the vacuolar …

THE molecular mechanisms by which Ca2+ controls a variety of ion transport-associated
cellular functions in higher plant cells1, including movements of stomatal pores, remain …

Free calcium (Ca2+) in the cytoplasm of plant cells is important for the regulation of many
cellular processes and the transduction of stimuli. Control of cytoplasmic Ca2+ involves the …

Abstract Cytosolic free calcium ([Ca2+] cyt) is a ubiquitous signalling component in plant
cells. Numerous stimuli trigger sustained or transient elevations of [Ca2+] cyt that evoke …

The central vacuole is the largest Ca2+ store in a mature plant cell. Ca2+ release from this
store contributes to Ca2+-mediated intracellular signalling in a variety of physiological …

A novel pathway for intracellular Ca2+ release via a voltage‐gated channel has been diered
in the tonoplast of Beta vulgaris (sugar beet) tap roots. The channel is characterized …

Activity of vacuolar ion channels can be regulated by the cytosolic free Ca2+ concentration
([Ca2+] cyt). Using the whole‐vacuole mode of patch‐clamp with Vicia faba guard cell …

In plants, stomata control the gaseous exchange between the intercellular spaces of the leaf
and the atmosphere. Fluxes of ions, in particular potassium fluxes, across the membranes of …

The slowly activating vacuolar (SV) channel of plant vacuoles is gated open by cytosolic free
Ca2+ and by cytosol-positive potentials. Using vacuoles isolated from broad bean guard cell …

In order to test the hypothesis that slowly activating vacuolar (SV) channels mediate Ca2+‐
induced Ca2+ release the voltage‐and Ca2+‐dependence of these K+ and Ca2+ …
