真核藻类传统上分为三大类：红藻、有色藻和绿藻。这些类群之间的进化关系，它们与其他真核生物和其他光合类群（如裸藻和隐藻）的联系，一直是许多争论和推测的主题1 - 8。在这里，我们分析的大（28 S）细胞质核糖体RNA的部分序列从10个新的原生生物属于不同的单细胞藻类。通过将它们与其他14个单细胞和多细胞真核生物的同源序列相结合，我们表明，红藻，有色植物和绿藻出现在真核生物之间的三个不同的群体晚，即接近后生动物-后生植物辐射。这意味着一个相对较晚发生的真核光合共生。我们还提供了门内和门间关系的细节。
EUKARYOTIC algae are traditionally separated into three broad divisions: the rhodophytes, the chromophytes and the chlorophytes. The evolutionary relationships between these groups, their links with other eukaryotes and with other photosynthetic groups, such as euglenophytes and cryptophytes, have been the subject of much debate and speculation1 –8. Here we analyse partial sequences of the large (28S) cytoplasmic ribosomal RNA from ten new species of protists belonging to various groups of unicellular algae. By combining them with the homologous sequences from 14 other unicellular and multicellular eukaryotes, we show that rhodophytes, chromophytes and chlorophytes emerge as three distinct groups late among eukaryotes, that is, close to the metazoa–metaphytes radiation. This implies a relatively late occurrence of eukaryotic photosynthetic symbiosis. We also provide details of intra- and inter-phyla relationships.
