In 1992, two independent reports based on small-subunit rRNA gene (SSU rDNA) cloning revealed the presence of novel Archaea among marine bacterioplankton. Here, we report the presence of further novel Archaea SSU rDNA sequences recovered from the midgut contents of a deep-sea marine holothurian. Phylogenetic analyses show that these abyssal Archaea are a paraphyletic component of a highly divergent clade that also includes some planktonic sequences. Our data confirm that this clade is a deep-branching lineage in the tree of life.
1992年,两项基于小亚基rRNA基因(SSU rDNA)克隆的独立报告显示,在海洋浮游细菌中存在新型古菌。在此,我们报告从一种深海海参的中肠内容物中 recovered(此处原文可能有误,推测是“回收”之类的意思,暂按“回收”翻译)到了更多新型古菌SSU rDNA序列。系统发育分析表明,这些深海古菌是一个高度分化的分支的并系组成部分,该分支还包括一些浮游序列。我们的数据证实,这个分支是生命之树中的一个深度分支谱系。
