Sakha – an area connecting South and Northeast Siberia – is significant for understanding the history of peopling of Northeast Eurasia and the Americas. Previous studies have shown a genetic contiguity between Siberia and East Asia and the key role of South Siberia in the colonization of Siberia. We report the results of a high-resolution phylogenetic analysis of 701 mtDNAs and 318 Y chromosomes f...... hiện toàn bộ
Growth reaction norms of domesticated, wild and hybrid Atlantic salmon families in response to differing social and physical environmentsSpringer Science and Business Media LLC - Tập 13 - Trang 1-23 - 2013
Monica Favnebøe Solberg, Zhiwei Zhang, Frank Nilsen, Kevin Alan Glover
Directional selection for growth has resulted in the 9-10th generation of domesticated Atlantic salmon Salmo salar L. outgrowing wild salmon by a ratio of approximately 3:1 when reared under standard hatchery conditions. In the wild however, growth of domesticated and wild salmon is more similar, and seems to differ at the most by a ratio of 1.25:1. Comparative studies of quantitative traits in fa...... hiện toàn bộ
The relationship of protein conservation and sequence lengthSpringer Science and Business Media LLC - - 2002
David J Lipman, Alexander Souvorov, Eugene V Koonin, Anna R Panchenko, Tatiana A Tatusova
In general, the length of a protein sequence is determined by its function and the wide variance in the lengths of an organism's proteins reflects the diversity of specific functional roles for these proteins. However, additional evolutionary forces that affect the length of a protein may be revealed by studying the length distributions of proteins evolving under weaker functional constraints. We ...... hiện toàn bộ
The mammary gland-specific marsupial ELP and eutherian CTI share a common ancestral geneSpringer Science and Business Media LLC - Tập 12 - Trang 1-21 - 2012
Elizabeth A Pharo, Alison A De Leo, Marilyn B Renfree, Peter C Thomson, Christophe M Lefèvre, Kevin R Nicholas
The marsupial early lactation protein (ELP) gene is expressed in the mammary gland and the protein is secreted into milk during early lactation (Phase 2A). Mature ELP shares approximately 55.4% similarity with the colostrum-specific bovine colostrum trypsin inhibitor (CTI) protein. Although ELP and CTI both have a single bovine pancreatic trypsin inhibitor (BPTI)-Kunitz domain and are secreted onl...... hiện toàn bộ
Evolution of the CD163 family and its relationship to the bovine gamma delta T cell co-receptor WC1Springer Science and Business Media LLC - Tập 10 Số 1 - 2010
Carolyn T.A. Herzig, Raymond Waters, Cynthia L. Baldwin, Janice C. Telfer
AbstractBackgroundThe scavenger receptor cysteine rich (SRCR) domain is an ancient and conserved protein domain. CD163 and WC1 molecules are classed together as group B SRCR superfamily members, along with Spα, CD5 and CD6, all of which are expressed by immune system cells. There are three known types of CD163 molecules in mammals...... hiện toàn bộ
Evolutionary factors affecting Lactate dehydrogenase A and B variation in the Daphnia pulexspecies complexSpringer Science and Business Media LLC - Tập 11 - Trang 1-12 - 2011
Teresa J Crease, Robin Floyd, Melania E Cristescu, David Innes
Evidence for historical, demographic and selective factors affecting enzyme evolution can be obtained by examining nucleotide sequence variation in candidate genes such as Lactate dehydrogenase (Ldh). Two closely related Daphnia species can be distinguished by their electrophoretic Ldh genotype and habitat. Daphnia pulex populations are fixed for the S allele and inhabit temporary ponds, while D. ...... hiện toàn bộ
EM for phylogenetic topology reconstruction on nonhomogeneous dataSpringer Science and Business Media LLC - - 2014
Esther Ibáñez-Marcelo, Marta Casanellas
The reconstruction of the phylogenetic tree topology of four taxa is, still nowadays, one of the main challenges in phylogenetics. Its difficulties lie in considering not too restrictive evolutionary models, and correctly dealing with the long-branch attraction problem. The correct reconstruction of 4-taxon trees is crucial for making quartet-based methods work and being able to recover large phyl...... hiện toàn bộ
