Cellular mechanisms of potassium transport in plants
DT Britto, HJ Kronzucker - Physiologia plantarum, 2008 - Wiley Online Library
Potassium (K+) is the most abundant ion in the plant cell and is required for a wide array of
functions, ranging from the maintenance of electrical potential gradients across cell
membranes, to the generation of turgor, to the activation of numerous enzymes. The majority
of these functions depend more or less directly upon the activities and regulation of
membrane‐bound K+ transport proteins, operating over a wide range of K+ concentrations.
Here, we review the physiological aspects of potassium transport systems in the plasma …
