Orussus abietinus

Representative of the wasp (Hymenoptera) family Orussidae: the parasitic wood wasp Orussus abietinus parasitizes wood-boring beetle larvae and exhibits numerous remarkable characteristics, such as an ovipositor that internally loops through the abdomen and thorax and eggs longer than the body size of the adult female. What makes parasitic wood wasps even more interesting, however, is the fact that they are the only lineage of parasitic wasps that primarily do not possess a wasp waist. In fact, orussids are thought to be the sister lineage of the tremendously successful and species rich Apocrita. The latter include all primarily parasitic wasps with wasp waist and all ants and bees. Orussids are critical for understanding the evolution of a parasitoid life history and the associated adaptations at the genomic level.

Analysis Name Whole genome assembly of Orussus abietinus
Software Baylor College of Medicine genome assembly pipeline (NA)

Materials & Methods

Sequence generation for assembly. For this project we are generating fairly high coverage in a number of different insert sized libraries. The assembly strategy is based around a seed allpaths assembly (the Broad Allpaths assembler) followed by seed assembly improvement using homegrown tools, Atlas-link and Atlas-GapFill, which can significantly improve the results. Thus we generate sequence data to enable the Allpaths assembly. As of Nov 2011 this is: - 40X genome coverage in 180bp insert library (100bp reads forward and reverse); and 40X 3kb insert data. To enable better scaffolding and local gap filling we additionally generate 500bp, 1kb, 2kb, and 8kb insert sizes at > 20X coverage.
