Daphnia magna Genome Sequencing Project

PROJECT DESCRIPTION: Daphnia magna is regarded as the premier invertebrate model for ecotoxicological research. Because of Daphnia's central position in aquatic food webs and its accessibility to field and laboratory testing, this species is invariantly included in toxicological research for chemical effects on freshwater ecosystems. Daphnia are unusually sensitive to environmental contaminants and are key reference taxa for setting regulatory limits by environmental protection agencies around the globe. Of the nearly 500,000 records in the ECOTOX database, waterfleas represent 8% of all experimental data for aquatic organisms. The extensive literature on ecological research on Daphnia exceeds 4,000 articles over the past century (lately averaging a paper a day), and over 7,000 articles on cladocerans have been published since 1855. As part of the ongoing research activities of the Daphnia Genomics Consortium, this project sequences, assembles and annotates the D. magna genome. Genome information obtained from this distantly related species will help inform the maturing Daphnia pulex genome project and broaden understanding on the genome biology of Crustacea.

How can I participate in the Daphnia magna Genome Project?

PROJECT LEADER: The Center for Genomics and Bioinformatics
SUPPORT AND FUNDING: Members of the Daphnia Genomics Consortium
STATUS: Sequencing began June 2, 2008.
