Molecular phylogeny of Coniochaetales

Mycological Research, 2006
Although the taxonomy of ascomycetes has changed dramatically, generic delimitation within the recently proposed order Coniochaetales has not been resolved. In order to clarify the phylogenetic relationships of genera in the Coniochaetaceae, we performed a molecular study based on the analyses of the sequences of the partial SSU and of the variable ...

A molecular phylogeny of annelids

Cladistics, 2007
AbstractWe present parsimony analyses of annelids based on the largest taxon sample and most extensive molecular data set yet assembled, with two nuclear ribosomal genes (18S rDNA and the D1 region of 28S rDNA), one nuclear protein coding‐gene (Histone H3) and one mitochondrial ribosomal gene (16S rDNA) from 217 terminal taxa.

Molecular Phylogeny of Acipenserinae

Molecular Phylogenetics and Evolution, 1998
The family Acipenseridae consists of 25 extant sturgeon species (19 species of Acipenserinae and 6 species of Scaphirhynchinae). Together with two extant paddlefish species, Polyodon spathula and Psephurus gladius (Polyodontidae), it composes the order Acipenseriformes, the most numerous of all living "fossil" fishes.

A Molecular Phylogeny of Reptiles

Science, 1999
The classical phylogeny of living reptiles pairs crocodilians with birds, tuataras with squamates, and places turtles at the base of the tree. New evidence from two nuclear genes, and analyses of mitochondrial DNA and 22 additional nuclear genes, join crocodilians with turtles and place squamates at the base of the tree.

Molecular phylogeny of Fv1

Mammalian Genome, 1998
Alleles at the Fv1 gene of inbred mice confer resistance to infection and spread of vertically or horizontally transmitted murine leukemia viruses (MuLV). The nucleotide sequence of Fv1 bears similarity to the gag of a human endogenous retrovirus, HERV-L, but is more closely related to the gag-coding sequence of a newly described class of HERV-L ...

Molecular phylogeny of eukaryotes

Trends in Ecology & Evolution, 1994
Comparisons of ribosomal RNAs and various protein coding genes have contributed to a new view of eukaryote phylogeny. Analyses of paralogous protein coding genes suggest that archaebacteria and eukaryotes are sistergroups. Sequence diversity of small subunit rRNAs in protists by far exceeds that of any multicellular or prokaryote taxon.

Molecular phylogeny of Foraminifera a review

European Journal of Protistology, 2002
Foraminifera are traditionally defined as marine granuloreticuloseans characterized by the presence of a membraneous, agglutinated or calcareous test. This definition has been recently challenged by molecular phylogenetic studies which showed that Foraminifera include both testate and naked species and that they occur in marine, freshwater, and ...

A Molecular Phylogeny of the Eucestoda

The Journal of Parasitology, 1998
Evolutionary relationships among the orders of the Eucestoda were examined based on data derived from partial sequences of genes encoding 18S rRNA. Considered in this study were 47 species-level taxa, including 1 from Monogenea, 1 from Amphilinidea, both of which were used as outgroups, and 45 from 10 orders of Eucestoda.

Application and Accuracy of Molecular Phylogenies

Science, 1994
Molecular investigations of evolutionary history are being used to study subjects as diverse as the epidemiology of acquired immune deficiency syndrome and the origin of life. These studies depend on accurate estimates of phylogeny. The performance of methods of phylogenetic analysis can be assessed by numerical simulation studies and by the ...

A molecular approach to the phylogeny of Acanthamoeba

Biosystems, 1985
Isoenzyme electrophoresis of three different enzyme systems was used to compare 71 strains assigned to the 15 currently recognized species of Acanthamoeba. A phylogenetic (cladistic) analysis of the zymograms indicated an arrangement of strains in 15 distinguishable lineages, but not all corresponding to current taxonomic assignments.
