The entire nucleotide sequence containing the small-subunit ribosomal RNA gene (SSU rRNA) from the mitochondrial genome of Chondrus crispus was determined. To our knowledge, this is the first sequence of a mitochondrial 16S-like rRNA from a red alga. The length of this gene is 1,376 nucleotides. Its secondary structure was constructed and compared with other known secondary structures from eubacteria and from mitochondria of land plants, green and brown algae, and fungi. Phylogenetic trees were built upon SSU rRNA sequence alignment from mitochondria and eubacteria. The results show that rhodophytes and chromophytes provide additional links in the evolution of mitochondria between the green plant lineage and the "nonplant" lineages.
测定了皱波角叉菜线粒体基因组中包含小亚基核糖体RNA基因（SSU rRNA）的完整核苷酸序列。据我们所知，这是红藻线粒体16S样rRNA的首个序列。该基因长度为1376个核苷酸。构建了其二级结构，并与真细菌以及陆地植物、绿藻、褐藻和真菌线粒体的其他已知二级结构进行了比较。基于线粒体和真细菌的SSU rRNA序列比对构建了系统发育树。结果表明，红藻和色藻在绿色植物谱系与“非植物”谱系之间的线粒体进化中提供了额外的联系。
