Description
<p>Caesium (Cs) uptake in land plant is mainly carried out by potassium ion (K+) transport systems. Potassium ion uptake from the rhizosphere is regulated by two types of transport system, low affinity and high affinity transport systems, depending on the K+ concentration in soil solution. In both transport systems, there are several channels and transporters which mediate Cs+ transport also. In low affinity transport system, the inward-rectifying K+ and voltage-insensitive cation channels are involved in Cs+ uptake, while KUP/HAK/KT type transporters are the major Cs+ path in high affinity transport system. Within the plant body, Cs+ translocation is also mediated by outward-rectifying K+ channels. In addition to these Cs+ and K+ competitive transport systems, recent studies reported novel Cs+ transport systems without changing K+ behavior in plant. In this review, Cs+ transport systems dependent/independent to K+ transport mechanisms are introduced.</p>
