Phylogeny of molluscs and their relatives based on new molecular data

动物界主要可分为两大类：后口类和原口类。此外，后者可以进一步分裂成Lophotrochozoa包含ca。13个主要门和Ecdysozoa组成的ca.七个主要门。然而，在这两个主要群体中，很难找到任何共生关系的稳定和良好解决的解决方案。因此，在与其他科学家的合作中，我们打算创建一个稳定和良好解决的后生动物重建，特别是我和其他两个合作者对lophotrochozoan共生关系的关注。我个人的分析将主要集中在软体动物门和它们的潜在亲属星虫和内肛动物，分别。为了追踪这一点，我们将采取两种方法：（i）我们将分析一个巨大的EST集，并获得新基因的交叉，这可以用来追踪Lophotrochozoa以及Ecdysozoa和后口动物的（深层）生殖。第二种方法（ii）由10种已知的蛋白质共同在所有后生动物门，这将被额外分析，并作为一个共同的数据集，以重建后生动物类在寒武纪深部水平的发育，因为它是第一种方法。

The animal kingdom mainly can be subdivided into two major groups: Deuterostomes and Protostomes. Additionally, the latter ones can be split further into the Lophotrochozoa containing ca. 13 main Phyla and the Ecdysozoa consisting of ca. seven main Phyla. Within these two major groups however, a stable and well-resolved resolution of any phylogentic relationship can hardly to be found. Thus, in collaboration with other scientists we are intending to create a stable and well-resolved reconstruction of the Metazoa with special focus on the lophotrochozoan phylogeny by me and two other collaborates. My personal analyses will mainly focus on the Phylum Mollusca and their potential relatives the Sipunculida and the Entoprocta, respectively. To trace this, we will follow up two ways: (i) we will analyze a huge set of ESTs and obtain an intersection of new genes, which can be used to trace the (deep) phylogeny of the Lophotrochozoa as well as Ecdysozoa and deuterostomes. The second way (ii) consists of ten known proteins common in all metazoan phyla, which will be analyzed additionally and used as a common data set to reconstruct the phylogeny of the metazoan classes at the deep Cambrian level as it is for the first approach.
