Molecular phylogenic location of the Plagiorchis muris (Digenea, Plagiorchiidae) based on sequences of partial 28S D1 rDNA and mitochondrial cytochrome C oxidase subunit I.

ABSTRACT: To determine the molecular phylogenic location of Plagiorchis muris, 28S D1 ribosomal DNA (rDNA) and mitochondrial cytochrome C oxidase subunit I (mtCOI) were sequenced and compared with other trematodes in the family Plagiorchiidae. The 28S D1 tree of P. muris was found to be closely related to those of P. elegans and other Plagiorchis species. And, the mtCOI tree also showed that P. muris is in a separate clade with genus Glypthelmins. These results support a phylogenic relationship between members of the Plagiorchiidae, as suggested by morphologic features.

Project description:To facilitate the process of spiral nematode species delineation, populations of Helicotylenchus canadensis, H. pseudorobustus, and H. varicaudatus deriving from various locations and diverse natural and anthropogenic environments from Poland were investigated and characterized. For the first time, 28S rDNA sequences are reported for H. canadensis and H. varicaudatus, whereas new mtCOI sequences were acquired for all three analyzed species. A Bayesian phylogenetic analysis of the 28S rDNA fragments revealed that H. canadensis and H. varicaudatus are members of a clade that is a sister group to all other Helicotylenchus species; however, the closest known sister group to H. canadensis is H. vulgaris type A. Both 28S rDNA- and mtCOI-based phylogenetic results suggest that this clade excludes H. pseudorobustus, whose most recent common ancestor with the former species was inferred to be the ancestor of all Helicotylenchus species. Moreover, within the mtCOI sequences obtained from H. pseudorobustus, unlike from the other two, a simultaneous presence of TAG and TAA codons was identified. This may indicate mitochondrial genetic code alterations or other genomic rearrangements in H. pseudorobustus.To facilitate the process of spiral nematode species delineation, populations of Helicotylenchus canadensis, H. pseudorobustus, and H. varicaudatus deriving from various locations and diverse natural and anthropogenic environments from Poland were investigated and characterized.
