Utility of a juvenile fathead minnow screening assay for detecting (anti-)estrogenic substances.

abstract：:Ab initio gene prediction and evidence alignment were used to produce the first annotations for the fathead minnow (Pimephales promelas) genome. We also describe a genome browser, hosted by the Society of Environmental Toxicology and Chemistry, that provides simplified access to the annotation data in context with the...
