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 Foraminifera a review
European Journal of Protistology, 2002Foraminifera 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, 1998Evolutionary 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.

Molecular phylogeny of eukaryotes
Trends in Ecology & Evolution, 1994Comparisons 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.

A Molecular Phylogeny of Costaceae (Zingiberales)
Molecular Phylogenetics and Evolution, 2001The phylogenetic relationships of Costaceae, a tropical monocotyledonous family sister to the gingers (Zingiberaceae), were investigated with a combination of two chloroplast loci (the trnL-F locus, including the trnL intron, the 3'trnL exon, and the trnL-F intergenic spacer, and the trnK locus, including the trnK intron and the matK coding region) and

Application and Accuracy of Molecular Phylogenies
Science, 1994Molecular 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, 1985Isoenzyme 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.

Molecular Phylogeny of the Arenaviruses
2002Molecular approaches to the identification of viruses and the delineation of relationships among them has emerged as an important tool in virology only within the past 10–15 years. The rapidity and precision with which virus genetic sequences can now be acquired and the development of sophisticated methods for the phylogenetic analysis of this new ...

THE MOLECULAR PHYLOGENY AND SYSTEMATICS OF THE ACTINOMYCETES
Annual Review of Microbiology, 1994Sequences of 16S ribosomal RNA have provided actinomycetologists with a phylogenetic tree that allows the investigation of the evolution of actinomycetes and also provides a basis for classification. The origin of actinomycetes and, except for bifidobacteria, the order by which the main sublines evolved, cannot yet be determined with certainty. However,

A Molecular Phylogeny of the Human Schistosomes
Molecular Phylogenetics and Evolution, 1995Members of the genus Schistosoma are generally grouped on the basis of egg morphology, intermediate host specificity, and geographic origin. We have tested hypotheses based on these groupings by phylogenetic analysis of nuclear ribosomal (ITS2) and mitochondrial (COI) nucleotide sequences.
