Research Abstract |
Many strains that could be identified as Plagioselmis sp. and Teleaulax sp.based on morphological characters were isolated from various coastal waters of Japan. Because rDNA sequences including ITS of these strains were nearly identical and the cells of a strain of Teleaulax sp. transferred to those of Plagioselmis sp., only one species of Plagioselmis-clade that possessed life cycle composed of Plagioselmis sp. stage and Teleaulax sp. stage was common in Japanese coastal waters. In addition, the phylogenetic analysis suggested that the family Geminigeraceae (including Plagioselmis-clade) was ancestral paraphyletic group in the Cryptophyceae. This finding provided various insights to consider the evolution of the Cryptophyceae.
