Max Planck scientists develop gene switch for chloroplasts in plant cells

In order for a gene to create a protein, the gene's DNA must first be converted into what's known as messenger RNA. These RNA molecules are the instruction manuals that show the ribosomes - the cell's protein factories - how to build a protein. A few years ago, scientists studying bacterial cells discovered sections in certain messenger RNAs that metabolic products (metabolites) can bind to. In doing so, they induce the RNA molecule to change its spatial structure and make it possible to switch protein production on or off. For the bacteria, these sections - the riboswitches - provide a fast and efficient way of controlling protein synthesis. Unsurprisingly, it had previously been impossible to demonstrate the presence of such riboswitches in the chloroplasts of plant cells...
