Evolutionary relationships of eukaryotic kingdoms

Journal of Molecular Evolution, 1996
The evolutionary relationships of four eukaryotic kingdoms--Animalia, Plantae, Fungi, and Protista--remain unclear. In particular, statistical support for the closeness of animals to fungi rather than to plants is lacking, and a preferred branching order of these and other eukaryotic lineages is still controversial even though molecular sequences from ...

Origins and Evolutionary Relationships of Retroviruses

The Quarterly Review of Biology, 1989
As is the case for some other RNA viruses, the amino acid sequences of retroviral proteins change at an astonishing rate. For example, the proteases of the human immunodeficiency virus (HIV) and the visna lentivirus with which it is often compared are as different as the proteases of fungi and mammals, and those of the human type I leukemia virus are ...

Spiroplasmas: evolutionary relationships and biodiversity

Frontiers in Bioscience, 2006
Spiroplasmas are wall-less descendants of Gram-positive bacteria that maintain some of the smallest genomes known for self-replicating organisms. These helical, motile prokaryotes exploit numerous habitats, but are most often found in association with insects.

Evolutionary relationships among the serpins

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1993
Abstract The serpins are a widely distributed group of serine proteinase inhibitors found in plants, birds, mammals and viruses. Despite the great evolutionary divergence of these organisms, their serpins art highly conserved, both in sequence and structurally. Amino acid sequences were aligned by a combination of automatic algorithms

Introduction to Inferring Evolutionary Relationships

Current Protocols in Bioinformatics, 2003
AbstractThis unit provides a general introduction to phylogeny. It defines common terms and discusses the issue of rooting trees, in addition to comparing gene and species trees. Methods for inferring phylogenies, such as distance methods, parsimony methods, and maximum likelihood are also presented.

Evolutionary Relationships in the Genus Mus

1986
The Murids, with their many genera, are the most diversified and recent group of Rodents. Mus, along with Rattus and a few others, has been recognized as a separate taxon for a long time. One of its numerous species, the house mouse, has become the most studied vertebrate probably because its habitat is closest to that of man.
