Changing styles in C. elegans genetics

The past 30 years have taken the nematode Caenorhabditis elegans from obscurity, as a nondescript member of a large but unglamorous invertebrate phylum, to a position as one of the major model organisms. This year, it will acquire a particular celeberity as the owner of the first animal genome to be sequenced in its entirety. In this review we consider the ways in which genetical investigations of this species have begun to change and what some of the consequences of the completion of the sequence are likely to be.
