Christiane Nüsslein-Volhard uncovered genes directing embryo development
Born on 20 October 1942, German geneticist Christiane Nüsslein-Volhard conducted systematic genetic screens in Drosophila that identified the primary maternal and zygotic genes governing embryonic patterning.
Working alongside Eric Wieschaus in Heidelberg, Nüsslein-Volhard systematically mutated fruit fly genes to identify every gene required for early body segmentation and polarity. Their systematic screen uncovered key regulatory cascades, including gap genes, pair-rule genes, and segment polarity genes.
The work demonstrated that complex anatomical patterning is controlled by universal genetic programs shared across species, earning Nüsslein-Volhard and Wieschaus the 1995 Nobel Prize in Physiology or Medicine.
