The Struggle for Iron (VIDEO) Max Planck Institute for Chemical Ecology This video is under embargo. Please login to access this video. Caption Maize plants release secondary metabolites into the soil that bind to iron and thereby facilitate its uptake by the plant. The Western corn rootworm (Diabrotica virgifera), the economically most important maize pest worldwide, is attracted by these complexes, extracts the bound iron from the maize plant and uses it for its own nutrition. With these insights, researchers from the University of Bern, Switzerland, and the Max Planck Institute for Chemical Ecology in Jena, Germany, provide a new explanation for the extraordinary success of the Western corn rootworm as a global maize pest. The study was published in the journal Science.
