This article presents analysis of the draft genome sequence of a free-living nematode. It reveals striking protein family expansions that likely result from selection in a harsh environment with pathogens. For example, expansion of a eukaryotic release factor protein family suggests an ongoing evolutionary arms race with viruses and transposons. The authors describe a resource that will enable experimental analysis of interesting developmental and behavioral features of this worm, such as its gonad development and use of ascaroside social signals.
