- Abstract
A team of researchers from the University of Tübingen has discovered a receptor in wild potatoes that makes them resistant to potato blight. The receptor, called Pep-13 Receptor Unit (Peru), recognizes the protein fragment Pep-13 from the late blight fungus that causes potato blight. Other variants of Peru that bind to different molecules have also been identified. Researchers from Homburg and Freiburg have found that the transmembrane protein TIM17 transports proteins into the mitochondria by opening the membrane in a trough-like shape. It was previously believed that TIM23 was responsible for this process. A US research group uses DNA as a data carrier that can change in parallel and allows for binary counting operations. DNA has a higher information density than magnetic and optical storage media, but is currently more expensive and slower in computation. Scientists from the University of Saarland and their US colleagues have investigated the mechanism of action of the protein OPA1 and found that it attaches to the inner membrane of the mitochondria and opens it. Faulty OPA1 can lead to degenerative diseases.
