Zebrafish (www.zfin.org) :
The zebrafish is an inch-long tropical fish with rapidly-developing, transparent embryos and a powerful bag of genetic tricks developed by the late George Streisinger at the University of Oregon in the early 1970s, when he was the only zebrafish geneticist. Of three scientists sharing the 1995 Nobel Prize in Biology for the generation of developmental mutants in Drosophila, one, Nusslein-Volhard, has now completed a large-scale mutant screen in zebrafish (see the special Zebrafish issue of Development, December 1996). Its genome is currently being sequenced at the Sanger Center). Such work has made the zebrafish a premier vertebrate genetic model system (used now by about 500 research laboratories worldwide).
