Plants show enormous variety in traits relevant to breeding, such as plant height, yield and resistance to pests. One of the greatest challenges in modern plant research is to identify the differences in genetic information that are responsible for this variation. A research team led by the „Crop Yield“ working group at the Institute for Molecular Physiology at Heinrich Heine University Düsseldorf (HHU) and the Carnegie Institution of Science at Stanford has now developed a method to identify precisely these special differences in genetic information.
