Spezifische Membrankontaktstellen bei Pflanzen: wer mit wem, warum und wie

Cellular membranes can serve as barriers between subcellular compartments, but they can also interact to form dynamically regulated membrane contact sites between a specific pair of organelles. Focussing on plants, this article discusses local redox environments and the current knowledge on membrane contact sites as examples for the dividing and connecting functions of membranes, respectively.
