How do plant cells accomplish a net uptake of Ca 2+ but keep the membrane potential
under control? Consideration of the voltage dependence of the depolarization-activated …

Numerous biological assays and pharmacological studies on various higher plant tissues
have led to the suggestion that voltage‐dependent plasma membrane Ca2+ channels play …

plant Ca2+‐permeable ion channels 50 III. Ca2+ extrusion systems 61 IV. Concluding …

Rapid influx of Ca2+ into the cytosol from extracellular pools or intracellular stores via ion
channels can have wide-ranging physiological consequences. In addition, influx of Ca2+ …

Voltage patch-clamp experiments at the whole-vacuole and single-channel levels were
employed to study the retrieval of Ca2+ from vacuoles into the cytoplasm in sugar beet cell …

A voltage-independent cation (VIC) channel has been identified in the plasma membrane of
wheat (Triticum aestivum) root cells (PJ White [1999] Trends Plant Sci 4: 245–246). Several …

An increasing number of studies imply that Ca2+ mobilization from intracellular stores plays
an important role in stimulus evoked elevation of cytosolic free calcium during signal …

Calcium is an essential and major plant nutrient. It is required for structural, osmotic and
signalling purposes. In this review the pathway and molecular mechanisms are described by …

Calcium signal transduction is a central mechanism by which plants sense and respond to
endogenous and environmental stimuli. Cytosolic Ca2+ elevation is achieved via two …

Calcium channels are involved principally in signal transduction. Their opening results in
increased cytoplasmic Ca2+ concentration, and the spatial and temporal variations in this …
