v.1.0 (July 5, 2007): Daphnia pulex genome assembly v1.0. The assembly release version 1.0 of whole genome shotgun reads was constructed with the JGI assembler, Jazz, using paired end sequencing reads at a coverage of 8.7x. After trimming for vector and quality, 1,591,853 reads assembled into 9080 scaffolds totaling 227.1 Mbp. Further exclusion of contaminant and mis-assembled scaffolds reduced this to 5191 scaffolds, with a total length of 197.3 Mbp. Roughly half of the genome is contained in 103 scaffolds all at least 469.5 Kb in length.The current draft release, version 1.0, includes a total of 30,907 gene models predicted and functionally annotated using the JGI annotation pipeline.
