Morphological and Ribosomal <scp>DNA</scp>‐based Characterization of Six Antarctic Ciliate Morphospecies from the Amundsen Sea with Phylogenetic Analyses
Abstract We characterized six tintinnid ciliates from Antarctic waters using molecular markers and morphological traits: Amphorellopsis quinquealata , Codonellopsis gaussi , Cymatocylis convallaria , Cy. calyciformis , Cy. drygalskii, and Laackmanniella prolongata . The 100% similarity in SSU‐ITS1‐5...

Summary: | Abstract We characterized six tintinnid ciliates from Antarctic waters using molecular markers and morphological traits: Amphorellopsis quinquealata , Codonellopsis gaussi , Cymatocylis convallaria , Cy. calyciformis , Cy. drygalskii, and Laackmanniella prolongata . The 100% similarity in SSU‐ITS1‐5.8S rDNA ‐ITS2‐partial LSU rDNA sequences among Cy. convallaria , Cy. calyciformis, and Cy. drygalskii is supportive of synonymy. Codonellopsis gaussi and L. prolongata also showed high levels of similarity in SSU rDNA (99.83%) and the D2 domain of LSU rDNA (95.77%), suggesting that they are closely related. Phylogenetic analysis placed Cymatocylis in the Rhabdonellidae, Amphorellopsis in the Tintinnidae and L. prolongata/Co. gaussi within the Dictyocystidae. |
