Magellan Mutation

Caption: Motor nerves growing toward their muscle targets are detected with fluorescent protein in transgenic mouse embryos. A normal (wild type) embryo is shown in green and different mutants isolated in a genetic screen are shown in yellow (Columbus), red (Magellan), and blue (DeLeon). A variety of motor neuron growth and development defects are apparent in the mutants.
