Abstract

The gene for the mitochondrial small subunit rRNA (SSUrRNA) from the heterotrophic alga Prototheca wickerhamii has been isolated from a gene library of extranuclear DNA. Sequence and structural analyses allow the determination of a secondary structure model for this rRNA. In addition, several sequence motifs are present which are typically found in SSUrRNAs of various mitochondrial origins. Unexpectedly, the Prototheca RNA sequence has more features in common with mitochondrial SSUrRNAs from plants than with that from the green alga Chlamydomonas reinhardtii. The phylogenetic relationship between mitochondria from plants and algae is discussed.

摘要

已从异养藻类威克汉姆原囊藻（Prototheca wickerhamii）的核外DNA基因文库中分离出线粒体小亚基rRNA（SSUrRNA）基因。序列和结构分析使得能够确定该rRNA的二级结构模型。此外，还存在几个序列基序，这些基序通常在各种线粒体来源的SSUrRNAs中发现。出乎意料的是，原囊藻RNA序列与植物线粒体SSUrRNAs的共同特征比与莱茵衣藻（Chlamydomonas reinhardtii）的线粒体SSUrRNAs更多。本文讨论了植物和藻类线粒体之间的系统发育关系。
