Up to 2003 this confirmed that the ... A. However, the characterization and subsequent phylogenetic analysis of the viral strains involved in the ...

AIBS honors outstanding contributions to biology

... (evolutionary trees), including likelihood and bootstrap methods and phylogenetic comparative methods. He has also worked on likelihood inference using ... Phylogenies. By playing a major role in establishing a rigorous basis for phylogenetic inference, Felsenstein has enhanced the field of systematics, has helped ...

EMBL GeneCore purchases Genomatix's next generation sequencing data analysis solution

... or any other mapping procedure. Clustering and peak finding, analysis for phylogenetic conservation, large scale correlation analysis with annotated genomic ... over-representation, binding partner analysis, framework identification, phylogenetic conservation, regulatory SNP effects) and much more are all processes ...

Evolutionary history of SARS supports bats as virus source

... amounts of data, comparing the viral genomes and building what is called a phylogenetic tree by searching for shared mutations. Phylogenetics is the study of the ... diagram that illustrates the interrelationship of various viruses. The phylogenetic tree also shows the timeline of the travels and mutations of various ...

Study uncovers cause of flu epidemics

... sampled between 1918 and 2006 and representing 17 different countries on five continents. Using the genome data, the researchers constructed phylogenetic trees representing evolutionary relationships across all eight genome segments of the virus. Big differences in the shapes of these eight trees ...

Novel virus detection identifies new viruses in study of respiratory infections and asthma attacks

... and specific. The method detected remarkable and unanticipated diversity of viruses linked with RTIs and identified a wholly new branch of the phylogenetic tree, for the human rhinovirus, one of the causative agents of the common cold virus, Dr. Kistler notes, showing that even with a small test group ...

Protein Folds Research Offers Insight into Metabolic Evolution

... work relies on reputable techniques of phylogenetic analysis developed in the past decade to plot the ... Jay E. Mittenthal. We are using the techniques of phylogenetic analysis that systematicists used to build the ... They combined these two data sets with phylogenetic reconstructions, or family trees, of protein fold ...

Primates reveal a new dimension to human genome

So far only a study on the mouse or ... which gives scope for a better study. The phylogenetic shadowing process enables the identification of ...

Evoprinter, a multigenomic comparative tool for rapid identification of functionally important DNA

... and its transcriptional regulators. This cross-species comparison, termed phylogenetic footprinting, is based on the hypothesis that functionally important sequences evolve at a significantly slower rate than nonfunctional DNA. phylogenetic footprinting has been used successfully to discover multispecies-conserved ...

Evolution of HIV from African Greek Monkeys

... into grivets or northeast into grivets and then south into vervets. Wertheim said, "I was surprised that the geography could explain the virus phylogenetic tree, how well it fit. You just look and -- there it is!" The UA researchers suggest that in the border zones where two African green monkey ...

Color Vision Drove Primates to Develop Red Skin and Hair, Study Finds

... data on the color vision, social and sexual habits and red skin and pelage of 203 different primate species. The researchers then used a phylogenetic tree representing the evolutionary relationships among all the primate species under study to test hypotheses about the order in which the traits of ...

Evolution of Plant Life Cycle

... "As humans, we're always interested in knowing where we came from and why we are different from other primates," Qiu said. "Now that we know, from phylogenetic analyses, that our closest relative is the chimpanzee, we can compare the chimpanzee genome with our own genome and compare the chimpanzee brain with ...

US Academy honors 15 for major contributions to science

... seminal insights and methods for using computers as an aid to characterizing protein function, in comparing amino acid sequences, and for phylogenetic reconstructions." The award carries a medal and a prize of $ 25,000. Gibbs Brothers Medal, awarded every three years for outstanding contribution ...
