Abstract

Over millions of years, plants have evolved a sophisticatednetwork of K+ transport systems. This Botanical Briefing providesan overview of K+ transporters in various leaf tissues (epidermis,mesophyll, guard cells and vascular system) at both the cellularand organelle levels. Despite the tremendous progress in ourknowledge of genes encoding K+ transport systems in plants,understanding has not developed of coordinated functioning andoperation of these genes or proteins in the context of wholeplant physiology and plant–environment interaction. ThisBotanical Briefing is aimed at filling that gap by analysingelectrophysiological and molecular evidence for mechanisms coordinatingK+ transport between various leaf cells and tissues in changingenvironments.
