Monophyly of clade III nematodes is not supported by phylogenetic analysis of complete mitochondrial genome sequences
BackgroundThe orders Ascaridida, Oxyurida, and Spirurida represent major components of zooparasitic nematode diversity, including many species of veterinary and medical importance. Phylum-wide
Identification of genes suitable for DNA barcoding of morphologically indistinguishable Korean Halichondriidae sponges.
Use of the guidelines for species thresholds suggested in the recent literature indicates that the mtDNA regions are not appropriate for use as species-specific DNA markers for the Halichondriidae sponges, whereas the rDNA ITS regions are suitable because ITS exhibits a low level of intraspecific variation and a relatively high level of interspecific variation.
Salivary Transcriptome of the North American Medicinal Leech, Macrobdella decora
An Expressed Sequence Tag (EST) library-based analysis of the salivary transcriptome of the North American medicinal leech, Macrobdella decora, reveals a complex cocktail of anticoagulants and other bioactive secreted proteins not previously known to exist in a single leech.
Taxonomic Redescriptions of Two Ciliates, Protogastrostyla pulchra n. g., n. comb. and Hemigastrostyla enigmatica (Ciliophora: Spirotrichea, Stichotrichia), with Phylogenetic Analyses Based on 18S
It is concluded that these two species may represent some lower groups in the subclass Stichotrichia, and that G. pulchra should represent a new genus, Protogastrostyla n.
Morphological Descriptions of New and Little‐Known Benthic Ciliates from Ganghwa Tidal Flat, Korea
Several new and interesting taxa are discovered from the top layer sediment of a muddy site in the Ganghwa tidal flat, including three new species Spirodysteria ganghwaensis n.
Comparative analysis of complete mitochondrial genome sequences confirms independent origins of plant-parasitic nematodes
Phylogenetic trees inferred from nucleotide and amino acid sequences of mtDNA coding genes are in agreement that B. xylophilus is not closely related to Tylenchoidea, indicating that these two groups of plant parasites do not share an exclusive most recent common ancestor, and that certain morphological similarities between these stylet-bearing nematodes must result from convergent evolution.
Intraspecific hybridization of Anopheles sinensis (Diptera: Culicidae) strains from Thailand and Korea.
It is concluded from these results and previous vector ability studies that the An.
Bacterial symbiont and salivary peptide evolution in the context of leech phylogeny
The combined information content of a well corroborated leech phylogeny and broad taxonomic coverage of expressed proteins leads to a rich understanding of evolution and function in leech history.
