| 中文摘要 | The Nassophorea and Prostomatea are two of the key classes in understanding the morphological diversification and higher classification of the phylum Ciliophora. However, their phylogenetic relationships with other ciliate groups within the subphylum Intramacronucleata remain elusive. In this study, we investigated the small and large subunit (SSU and LSU) rRNA gene-based phylogeny of these groups with sequences of additional taxa including several key species. The results show that: (1) the class Nassophorea remains polyphyletic, with the microthoracids clustering with the Phyllopharyngea, whereas the nassulids represent a basal group of the CONthreeP superclade in the SSU tree; (2) the Prostomatea is not depicted as a monophyletic group in phylogenetic trees, and the monophyly of this class is marginally rejected by statistical tree topology tests; (3) the nassulid genus Parafurgasonia is more closely related to the family Colpodidiidae than to Furgasonia; (4) Paranassula, which was previously thought to be a nassulid, is phylogenetically related to the oligohymenophorean peniculids in both the SSU and LSU trees; (5) the microthoracid genus Discotricha does not group with the other microthoracids in either SSU or LSU trees; (6) the family Plagiocampidae is closely related to the prostome parasite Cryptocaryon irritans and to the family Urotrichidae in the order Prorodontida; and (7) the family Placidae, represented by Placus salinus, is sister to the family Holophryidae in the order Prorodontida. Based on the present data, we consider the genus Discotricha to be an unclassified taxon within the CONthreeP. We also propose resurrecting the order Paranassulida and classifying it within the subclass Peniculia, class Oligohymenophorea. Primary and secondary structure signatures for higher taxa within Phyllopharyngea and Nassophorea are supplied. (C) 2013 Elsevier Inc. All rights reserved. |
