For a new plant to grow from a seed, cells need to divide numerous times. Daughter cells can each take on different tasks and sometimes vary in size. How plants determine the plane of cell division in this process, known as mitosis, is being researched by Prof. Dr. Ralf Reski and Dr. Elena Kozgunova from the University of Freiburg in a joint effort with Prof. Dr. Gohta Goshima from Nagoya University.
