Psolus sp. RWR-2015 Transcriptome or Gene expression. Psolus sp. RWR-2015

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.

为明晰现生棘皮动物的系统发育关系并确定海座星属（Xyloplax）的分类地位，本研究采用RNA测序（RNA-Seq）技术，从覆盖5个现生棘皮动物纲各深层分化支系的40种棘皮动物的转录组中，调取大量直系同源基因座；本研究旨在获取在海星纲（Asteroidea）、海参纲（Holothuroidea）、海胆纲（Echinoidea）、蛇尾纲（Ophiuroidea）及海百合纲（Crinoidea）中均具有充分代表性的直系同源肽序列。
