Rice plants grow nearly all over the world: in 89 countries on six of seven continents there are rice fields. For half of the worlds population rice is the most important staple food and the many rice varieties are constantly being improved through selective breeding. Scientists from the Max Planck Institute for Developmental Biology in Tübingen and their colleagues from the International Rice Research Institute in the Philippines succeeded in accelerating rice plant breeding by using artificial small RNA molecules.
