...S. Schulte-Merker; R. K. Ho; B. G. Herrmann; C. NÜsslein-Volhard ABSTRACT Embryos mutant for the T gene, in mice, make insufficient mesoderm and fail to develop a notochord. We report the cloning and sequencing of the T gene in the zebrafish (Brachydanio rerio) and show the nuclear localization...
