摘要：

The small subunit ribosomal RNA (rRNA) sequence of Gracilaria lemaneiformis Bory Weber‐van Bosse was inferred from analysis of rRNA coding regions that were amplified by the polymerase chain reaction method. Comparison of the G. lemaneiformis small subunit rRNA to homologous genes of diverse eukaryotes demonstrated that the red algal divergence was nearly simultaneous with the separation of plants, fungi, animals and many other protist lineages. This result conflicts with those of 5S rRNA sequence and plastid based phytogenies which suggest that red algae represent an early divergence in the eukaryotic line of descent. Further, algae appear to be of polyphyletic origin and red algae are unrelated to higher fungi. Copyright © 1990, Wiley Blackwell. All rights reserved
