Molecular phylogeny of kinorhynchs

Molecular Phylogenetics and Evolution, 2013
We reconstructed kinorhynch phylogeny using maximum-likelihood and Bayesian analyses of nuclear 18S and 28S rRNA gene sequences from 30 species in 13 genera (18S) and 23 species in 12 genera (28S), representing eight families and both orders (Cyclorhagida and Homalorhagida) currently recognized in the phylum. We analyzed the two genes individually (18S

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.

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 ...

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 ...

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 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.

Statistical tests of molecular phylogenies.

Methods in enzymology, 1990
This chapter provides a summary of methods for testing the significance of inferred phylogenies. In terms of parsimony a nucleotide site is informative (useful) for choosing among the three trees only if it is in the same state in two of the four species and in another state in the other two species.

A molecular phylogeny of bryozoans

Molecular Phylogenetics and Evolution, 2012
We present the most comprehensive molecular phylogeny of bryozoans to date. Our concatenated alignment of two nuclear ribosomal and five mitochondrial genes includes 95 taxa and 13,292 nucleotide sites, of which 8297 were included. The number of new sequences generated during this project are for each gene:ssrDNA (32), lsrDNA (22), rrnL (38), rrnS (35),
