With the abundance of molecular data now available it seems timely to link this information with the wealth of data previously accumulated on the physiology of plant K+ acquisition. The ultimate goal of all this research is to gain a better understanding of K+ transport and nutrition in the intact plant. Thus it is important to begin to integrate the molecular research with results from biochemical and physiological research conducted at the cellular, root and whole plant levels. This article will focus on describing the features of the cloned K+ transporters and their possible roles in mediating high- and low-affinity K+ uptake from the soil, as well as how K+ acquisition may be regulated.
