MaxPlanckResearch 4/2012Untrue to Type
When plant pollen fertilizes an ovum, the genetic material in the nucleus and the chloroplasts must harmonize. Stephan Greiner from the Max Planck Institute of Molecular Plant Physiology in Golm, near Potsdam, would like to find out which factors in the chloroplasts prevent the interbreeding of plant species. To do this, he works with a model plant that’s not too particular when it comes to the species boundary: the evening primrose.
MaxPlanckResearch 1/2012Getting to the Root of Things
Plants have lived in close community with certain fungi for millions of years. The microorganisms provide them with vital mineral salts such as phosphate, and in return, they supply the fungi with carbohydrates. Franziska Krajinski from the Max Planck Institute of Molecular Plant Physiology in Golm observes how these unequal partners establish contact with each other and exchange nutrients.
