Molecular Morphology of the Metazoa, with Special Reference to the Lophotrochozoa (MOLMORPH)

在《新动物系统发育》中，长肢动物的概念（即包括长肢动物、触手动物和螺旋体动物在一个分支中，而不包括节肢动物）仍然是一个备受争议的问题。到目前为止，分子数据未能推断出光藻动物门的相互关系，现有的形态学数据也没有定论。高度创新的分析类型称为分子形态学（即，所研究分子的二维或三维结构的形态分析）应该提供新的和有价值的数据领域。-通常用于深层系统发育的基因的2D / 3d结构（18s和28S rDNA， EF1a; HSP70, Myosin II）已知比一级结构（线性序列）保守得多。特别是InDels（插入或删除）成为2D / 3d图像中非常重要的字符。将重点放在有大量被广泛接受的进化枝存在的磷藻动物分类群上，对分子形态学数据集进行测试，并将增加新的特征来考虑。a型可以直接添加到形态学数据矩阵中，并且可能还会提高序列分析的质量，以便为序列替代模型的进化建模提供更好的见解。

Within the New Animal Phylogeny the concept of Lophotrochozoa (i.e. inclusion of Lophophorata = Tentaculata and Spiralia in one clade to the exclusion of Arthropoda) is still one of the heavily debated points. Up to now molecular data have failed to infer the interrelationship of lophotrochozoan phyla, and available morphological data are not conclusive. The highly innovative type of analysis called molecular morphology (i.e., the morphological analysis of 2D- or 3D-structure of the studied molecules) should provide new and valuable data fields. - The 2D-/3D-structures of genes usually applied for deep phylogeny (18 S and 28S rDNA, EF1a; HSP70, Myosin II) are known to be much more conservative than the primary structure (the linear sequence). In particular InDels (insertions or deletions) become highly significant characters in the 2D-/3D-image. Focusing on the lophotrochozoan taxa, where a large number of well-accepted clades exist, the molecular-morphological data-set will be tested and will add new characters to be considered. The type a can be directly added to a morphological data-matrix and will probably also improve the quality of the sequence analysis in order to provide better insights for evolutionary modelling of sequence substitution models.
