结果表明，内部转录间隔区2（ITS 2）序列-结构比对中的补偿性碱基变化（CBCs）可用于区分物种。使用ITS 2数据库结合4SALE -一种用于同步RNA序列和二级结构比对和编辑的工具-在这项研究中，我们提出了一个深入的CBC分析的扁形动物ITS 2序列和它们各自的二级结构。这一分析表明，至少有两个不同的物种Trichoplax（Placozoa）支持最近提出的假设，即Placozoa“不再是一个门”。
It was shown that compensatory base changes (CBCs) in internal transcribed spacer 2 (ITS2) sequence-structure alignments can be used for distinguishing species. Using the ITS2 Database in combination with 4SALE — a tool for synchronous RNA sequence and secondary structure alignment and editing — in this study we present an in-depth CBC analysis for placozoan ITS2 sequences and their respective secondary structures. This analysis indicates at least two distinct species in Trichoplax (Placozoa) supporting a recently suggested hypothesis, that Placozoa is “no longer a phylum of one”.
