Abstract
Potassium channels are found in all living organism from bacteria to men, and even in viruses. They were among the first transport proteins to be discovered on the molecular level. Pioneering work on potassium channel structure and function has led to the most comprehensive understanding about the physiology and regulation of potassium transport on cellular and organism levels. Since their discovery in 1984 by the first patch clamp in plants and the identification of genes encoding them in the early 1990s, potassium channels have advanced to the best understood transport proteins in plants. Starting with a brief introduction into the history of plant potassium transport, this review focuses on the molecular physiology of paradigmatic members of the “green” potassium channel family gained from studies in plants with sequenced genomes (the so-called model plants). We will then provide insights into our current knowledge of how channels find the membrane they control. Finally, the reader – in a plant signaling network context – will be introduced which triggers address the channel and how it responds.
