通过比较叶绿植物莱茵衣藻、金藻 Ochromonas danica 和卵菌双性 Achlya 之间的系统发育关系，研究人员通过比较它们的小亚基核糖体 RNA 编码区的序列来探索它们之间的系统发育关系。相似值的比较或通过距离矩阵方法构建的系统发育树的检查揭示了卵菌和金藻之间非常密切的关系。金藻植物与叶绿植物的分离类似于植物与动物的分离，并且这两种分离都远远早于许多其他原生生物群体的分歧。
The phylogenetic relationships among the chlorophyte Chlamydomonas reinhardtii, the chrysophyte Ochromonas danica, and the oomycete Achlya bisexualis were explored by comparing the sequences of their small-subunit ribosomal RNA coding regions. Comparisons of similarly values or inspection of phylogenetic trees constructed by distance matrix methods reveal a very close relationship between oomycetes and chrysophytes. The separation of chrysophytes from chlorophytes is comparable to that of plants from animals, and both separations are far antedated by the divergence of a number of other protist groups.
