Nuclear 28S rDNA phylogeny supports the basal placement of Noctiluca scintillans (Dinophyceae; Noctilucales) in dinoflagellates.

Abstract：

:Noctiluca scintillans (Macartney) Kofoid et Swezy, 1921 is an unarmoured heterotrophic dinoflagellate with a global distribution, and has been considered as one of the ancestral taxa among dinoflagellates. Recently, 18S rDNA, actin, alpha-, beta-tubulin, and Hsp90-based phylogenies have shown the basal position of the noctilucids. However, the relationships of dinoflagellates in the basal lineages are still controversial. Although the nuclear rDNA (e.g. 18S, ITS-5.8S, and 28S) contains much genetic information, DNA sequences of N. scintillans rDNA molecules were insufficiently characterized as yet. Here the author sequenced a long-range nuclear rDNA, spanning from the 18S to the D5 region of the 28S rDNA, of N. scintillans. The present N. scintillans had a nearly identical genotype (>99.0% similarity) compared to other Noctiluca sequences from different geographic origins. Nucleotide divergence in the partial 28S rDNA was significantly high (p<0.05) as compared to the 18S rDNA, demonstrating that the information from 28S rDNA is more variable. The 28S rDNA phylogeny of 17 selected dinoflagellates, two perkinsids, and two apicomplexans as outgroups showed that N. scintillans and Oxyrrhis marina formed a clade that diverged separately from core dinoflagellates.
