Based on molecular data a new taxon, Lophotrochozoa, was proposed comprising many mainly marine invertebrate taxa such as Annelida, Mollusca and Lophophorata (a.k.a. Tentaculata). However, the actual taxa composition of this taxon is still unresolved and thus the relationships within Lophotrochozoa are not well understood. Therefore, the purpose of the proposed projects herein is to determine, which taxa belong to Lophotro chozoa and how they are interrelated to each other. Furthermore, the taxon Annelida comprising traditionally Clitellata and Polychaeta is of special interest. Since a few decades the incorporation of different marine taxa within this taxon has been discussed more intensely. Especially, for the inclusion of Echiura and Siboglinidae (a.k.a. Pogonophora and Vestimentifera) the evidence is growing based on molecular and morphological data. On the other hand, the position of Sipuncula, Myzostomida and Kamptozoa relative to Annelida is still controversially discussed. Therefore, to address and test the different hypotheses concerning Lophotrochozoa and especially Annelida molecular data shall be gained from both EST databases and selected protein coding genes. This will enable us to perform multiple gene analyses within Lophotrochozoa for the first time.

基于分子生物学数据，提出了一个新的分类单元，Lophotrochozoa，包括许多主要的海洋无脊椎动物分类单元，如环节动物，软体动物和Lophophorata（a.k.a.）。触手纲）。然而，这个分类群的实际分类群组成仍然没有得到解决，因此Lophotrochozoa内的关系还没有得到很好的理解。因此，本文提出的项目的目的是确定哪些分类群属于Lophotro chozoa以及它们之间如何相互关联。此外，环节动物的分类群包括传统的Clitellata和多毛类是特别感兴趣的。几十年来，在本分类群内不同海洋分类群的合并已被更激烈地讨论。特别是，对于包括Echiura和Siboglinidae（a.k.a.根据分子和形态学数据，证据越来越多。另一方面，星虫目、裂口目和盘足目相对于环节动物的地位仍有争议。因此，要解决和验证有关散轮动物，特别是环节动物的不同假设，必须从EST数据库和选定的蛋白质编码基因中获得分子数据。这将使我们能够首次在Lophotrochozoa中进行多基因分析。
