| Abstract |
The large subunit ribosomal RNA sequences from the heterokont algae Ochromonas danica, Nannochloropsis salina, and Tribonema aequale were determined. These sequences were combined with small subunit ribosomal RNA sequences in order to carry out a phylogenetic analysis based on neighbor-joining, maximum parsimony, and maximum likelihood methods. Our results indicate that heterokont fungi and heterokont algae each are monophyletic, and confirm that they together form a monophyletic group called “stramenopiles.” Within the heterokont algae, the eustigmatophyte Nannochloropsis salina either clusters with the chrysophyte Ochromonas danica or forms a sister group to a cluster comprising the phaeophyte Scytosiphon lomentaria and the xanthophyte Tribonema aequale. The alveolates were identified as the closest relatives of the stramenopiles, but the exact order of divergence between the eukaryotic crown taxa could not be established with confidence. |
