Ladona fulva


The dragonfly Ladona fulva occurs primarily in Central Europe and is a typical predator of insects at small ponds and creeks with dense vegetation. Like all dragonflies, Ladona fulva features a special mode of flight (indirect-direct wing stroke) and a form of indirect sperm transfer via a secondary intromittent organ at the second and third segment of the male abdomen, demarcating Odonata from all other winged insects (Pterygota).

Due to their mode of flight, peculiar sperm transfer, and their phylogenetic origin, dragonflies are crucial to understand major evolutionary steps at the base of the insect tree of life. Dragonflies also serve as models for developing bionical applications that are used in the industry (e.g., wing stroke mechanisms, head arrester systems).

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.
