To better understand the phylogeny of extant echinoderms and the placement of Xyloplax, we employed RNA-Seq to retrieve large numbers of orthologous loci from each transcriptome of 40 echinoderm species spanning deep divergences within each of the five extant classes with the aim of discovering orthologous peptide sequences that were well represented in asteroids, holothuroids, echinoids, ophiuroids and crinoids.为更深入解析现生棘皮动物的系统发育关系，以及海座星属（Xyloplax）的分类地位，本研究采用RNA测序（RNA-Seq）技术，从覆盖现生5个棘皮动物纲各自的深度分化支系的40种棘皮动物的转录组中，获取了大量直系同源基因座，旨在挖掘在海星纲（asteroids）、海参纲（holothuroids）、海胆纲（echinoids）、蛇尾纲（ophiuroids）和海百合纲（crinoids）中均具有良好代表性的直系同源肽序列。
