摘要：

To date, no genes have been characterized from dinoflagellate mitochondrial DNA, Here we present the complete sequence of the gene (cox1) encoding subunit 1 of cytochrome c oxidase in the dinoflagellate, Crypthecodinium cohnii. Analysis of nucleotide and deduced amino acid sequences predicts a protein of 523 amino acids that is translated using universal initiation, stop and tryptophan codons. COX1 amino acid identity and phylogenetic tree analyses strongly support a close evolutionary relationship between dinoflagellates and apicomplexans; however, inclusion of the ciliates in this clade is less well supported, a result likely due to the highly derived nature of ciliate COX1 sequences.
