Abstract

Because algae have become more accepted as sources of human nutrition, phylogenetic analysis can help resolve the taxonomy of taxa that have not been well studied. This can help establish algal evolutionary relationships. Here, we compare Auxenochlorella protothecoides and 23 strains of Prototheca based on their complete 16S and partial 23S plastid rDNA sequences along with nutrient utilization (auxanographic) profiles. These data demonstrate that some of the species groupings are not in agreement with the molecular phylogenetic analyses and that auxanographic profiles are poor predictors of phylogenetic relationships.

摘要

由于藻类作为人类营养来源已越来越被接受，系统发育分析有助于解决尚未得到充分研究的分类单元的分类问题。这有助于建立藻类的进化关系。在此，我们基于完整的16S和部分23S质体rDNA序列以及营养利用（生长谱）概况，比较了原小球藻和23株原藻。这些数据表明，一些物种分组与分子系统发育分析不一致，并且生长谱概况对系统发育关系的预测能力较差。
