How to survive on low potassium

Potassium (K+) is taken up by roots and redistributed within organs and organelles by a large number of channels and transporters. Export of K+ stored in vacuoles, required to support growth under limiting conditions, is mediated by the interaction of K+ channels with a calcium-dependent signalling network.
