Christiane Nüsslein-Volhard is a German developmental biologist and director emeritus at the Max Planck Institute for Developmental Biology, celebrated for her landmark genetic screens that identified the genes controlling the body plan of the fruit fly Drosophila melanogaster. Together with Eric Wieschaus and Edward Lewis, she performed systematic saturation mutagenesis screens in the 1980s that revealed the complete genetic blueprint governing the anterior–posterior and dorsal–ventral axes of the fly embryo. These genes — gap genes, pair-rule genes, segment-polarity genes, and homeotic genes — turned out to be conserved across virtually all animals, including humans. The homeodomain proteins her group identified are key regulators of human development, and mutations in their human homologs underlie congenital malformations and certain cancers. Nüsslein-Volhard shared the 1995 Nobel Prize in Physiology or Medicine with Lewis and Wieschaus. She later applied genetic approaches to zebrafish pigmentation, contributing to understanding melanocyte biology and skin color genetics.
