With their own botanical collection material and their research knowledge on the evolution of cruciferous plants, i.e. plants of the cabbage family, bioscientists at Heidelberg University have contributed to a large-scale international study that has produced a comprehensive “tree of life” for flowering plants. For this purpose, researchers worldwide analysed the genetic information of more than 9,500 species from almost 8,000 genera. The Heidelberg scientists from the Centre for Organismal Studies were able to use comprehensive research material from living collections, seed collection and the herbarium.
