Priapulus caudatus belongs to the Priapulidae Family, a small group of marine and vermiform invertebrates of uncertain phylogenetic position. Priapulus caudatus

A draft assembly of the Priapulus caudatus genome sequence is expected. A BAC library is already under construction and a ~6X BAC end-sequencing will be performed. This project is part of a sequencing proposal submitted by an international group of universities whose main goal is to elucidate the evolutionary relationships within the Ecdysozoa. Sequencing of a total of 5 Ecdysozoa species will be undertaken at the Washington University Genome Sequencing Center.

预计将完成尾曳鳃虫（Priapulus caudatus）的基因组草图组装。目前细菌人工染色体（BAC）文库已处于构建阶段，后续将开展约6倍覆盖度的BAC末端测序。本项目是某国际高校联盟提交的测序项目提案的组成部分，其核心目标为阐明蜕皮动物总门（Ecdysozoa）内的演化关系。华盛顿大学基因组测序中心将对共计5种蜕皮动物总门物种开展测序工作。
