A new clade, based on partial LSU rDNA sequences, of unarmoured dinoflagellates.
The order Gymnodiniales comprises unarmoured dinoflagellates. However, the lack of sequences hindered determining the phylogenetic positions and systematic relationships of several gymnodinioid taxa. In this study, a monophyletic clade was defined for the species Ceratoperidinium margalefii Loeblich III, Gyrodinium falcatum Kofoid & Swezy, three Cochlodinium species, and two Gymnodinium-like di...
متن کاملRelationships of Scopulariopsis based on LSU rDNA sequences.
Relationships between Scopulariopsis species and allied fungi were studied by sequencing a 350 bp gene region of the large subunit ribosomal RNA gene (LSU rDNA). In addition, a limited morphological dataset of nine characters was included in the cladistic analysis. Nineteen mitosporic strains (nine Scopulariopsis, five Wardomyces, three Doratomyces, one Trichurus and one Scedosporium species) a...
متن کاملPhylogeny of the Peronosporomycetes ( Oomycota ) based on partial sequences of the large ribosomal subunit ( LSU rDNA )
The phylogeny of the nuclear large ribosomal subunit (LSU) rDNA from Peronosporomycetes (Oomycota) was studied. Five orders Rhipidiales, Leptomitales, Saprolegniales, Pythiales and Peronosporales were included in the study in order to reveal phylogenetic relationships within the group. Based on maximum parsimony, neighbour-joining and maximum-likelihood the Peronosporomycetes seem to have evolv...
متن کاملSphaeridiotrema globulus and Sphaeridiotrema pseudoglobulus (Digenea): species differentiation based on mtDNA (Barcode) and partial LSU-rDNA sequences.
Flukes belonging to Sphaeridiotrema are important parasites of waterfowl, and 2 morphologically similar species Sphaeridiotrema globulus and Sphaeridiotrema pseudoglobulus, have been implicated in waterfowl mortality in North America. Cytochrome oxidase I (barcode region) and partial LSU-rDNA sequences from specimens of S. globulus and S. pseudoglobulus, obtained from naturally and experimental...
متن کاملMolecular phylogeny of symbiotic dinoflagellates inferred from partial chloroplast large subunit (23S)-rDNA sequences.
Symbiotic associations between invertebrates and dinoflagellates of the genus Symbiodinium are a common occurrence in marine environments. However, despite our extensive knowledge concerning the physiological contributions of these algae to their symbiotic partners, our understanding of zooxanthella phylogenetics is still in its early stages. In the past 10 years, studies of Symbiodinium phylog...
