Psathyrometra fragilis Transcriptome or Gene expression. Psathyrometra fragilis

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.

为深入解析现生棘皮动物的系统发育关系以及Xyloplax的分类位置，我们采用RNA测序（RNA-Seq）技术，从覆盖5个现生棘皮动物纲内各深度分化支系的40个棘皮动物物种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、海参纲、海胆纲、蛇尾纲以及海百合纲中均具有良好代表性的直系同源肽序列。
