Ancient Phylogenetic Relationships

Theoretical Population Biology, 2002
Traditional views on deep evolutionary events have been seriously challenged over the last few years, following the identification of major pitfalls affecting molecular phylogeny reconstruction. Here we describe the principally encountered artifacts, notably long branch attraction, and their causes (i.e., difference in evolutionary rates, mutational ...

Taxonomy and phylogenetic relationship of zokors

Journal of Genetics, 2020
Zokor (Myospalacinae) is one of the subterranean rodents, endemic to east Asia. Due to the convergent and parallel evolution induced by its special lifestyles, the controversies in morphological classification of zokor appeared at the level of family and genus.

Phylogenetic relationships of cyphelloid homobasidiomycetes

Molecular Phylogenetics and Evolution, 2004
The homobasidiomycetes includes the mushroom-forming fungi. Members of the homobasidiomycetes produce the largest, most complex fruiting bodies in the fungi, such as gilled mushrooms ("agarics"), boletes, polypores, and puffballs. The homobasidiomycetes also includes species that produce minute, cup- or tube-shaped "cyphelloid" fruiting bodies, that ...

Phylogenetic analysis of anthropoid relationships

Journal of Human Evolution, 1998
The relationships of anthropoids to other primates are currently debated, as are the relationships among early fossil anthropoids and crown anthropoids. To resolve these issues, data on 291 morphological characters were collected for 57 taxa of living and fossil primates and analyzed using PAUP and MacClade.

Phylogenetic relationships within Colchicaceae

American Journal of Botany, 2003
Three plastid regions—the rps16 intron, the atpB‐rbcL intergenic spacer, and the trnL‐F region—in 73 taxa representing all the genera of Colchicaceae except Kuntheria were sequenced to investigate the intrafamilial relationships of the family. In total, the three gene regions, comprising 3830 characters, were analyzed both separately and in a combined ...

Phylogenetic relationships of the Santalales and relatives

Journal of Molecular Evolution, 1990
Determining relationships among parasitic angiosperms has often been difficult owing to frequent morphological reductions in floral and vegetative features. We report 18S (small-subunit) rRNA sequences for representative genera of three families within the Santalales (Olacaceae, Santalaceae, and Viscaceae) and six outgroup dicot families (Celastraceae,

Phylogenetic relationships among bacteriorhodopsins

Research in Microbiology, 1994
Retinal-containing proteins of archaea comprise a single family of homologous proteins that fall into three clusters correlating with function: the proton-transporting bacteriorhodopsins, the chloride-transporting halorhodopsins and the colour-discriminating sensory rhodopsins.

PHYLOGENETIC RELATIONSHIPS IN SEED PLANTS

Cladistics, 1985
Abstract— The phylogenetic relationships of nineteen extant and fossil seed plants are considered. Analysis of 31 characters produced ten topologically similar and equally parsimonious cladograms. A strict consensus tree derived from these cladograms places Lyginopteris as the sister taxon to the other seed plants included.

Phylogenetic Relationships of Fungal Cytochromesc

Yeast, 1997
The CYC1 gene encoding cytochrome c in the yeast Candida albicans was cloned by complementation of a cytochrome c-deficient mutant of Saccharomyces cerevisiae, and its DNA sequence was determined. The analysis of the amino acid sequences of cytochrome c from 14 fungal species and two isoforms from S.

Phylogenetic Relationships of a Large Marine Beggiatoa

Systematic and Applied Microbiology, 1999
Based upon 16S rRNA sequence and phenotypic similarities, a large, uncultured Beggiatoa sp. from the Bay of Concepción (Chile), is very closely related to the Chilean Thioploca species Thioploca araucae., whose filaments grow as sheathed bundles. The formation of sheathed filament bundles, the key character to distinguish the genus Thioploca from ...
