▪ Abstract Nonselective cation channels are a diverse group of ion channels characterized
by their low discrimination between many essential and toxic cations. They are ubiquitous in …

Calcium is an essential plant nutrient. It is acquired from the soil solution by the root system
and translocated to the shoot via the xylem. The root must balance the delivery of calcium to …

Many aspects of Ca2+ homeostasis in plants are similar to those in animals and fungi
(Poovaiah and Reddy, 1989), but an understanding of how Ca2+ transport and function are …

A new mechanism for calcium flux in wheat (Triticum aestivum L.) root cells has been
characterized. Membrane vesicles were enriched in plasma membrane using aqueous …

The Arabidopsis vacuolar CAtion eXchangers (CAXs) play a key role in mediating cation
influx into the vacuole. In Arabidopsis, there are six CAX genes. However, some members …

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 …

Calcium currents across the plasma membrane of plant cells allow transduction of
environmental signals as well as nutritive calcium uptake. Using transgenic Arabidopsis …

Considerable advances have been made, both in the technologies available to study
changes in intracellular cytosolic free Ca2+ ([Ca2+] i), and in our understanding of Ca2+ …

Cation transport is a critical process in all organisms and is essential for mineral nutrition,
ion stress tolerance, and signal transduction. Transporters that are members of the …

Cation levels within the cytosol are coordinated by a network of transporters. Here, we
examine the functional roles of calcium exchanger 1 (CAX1), a vacuolar H+/Ca2+ …
