  1. 1. Probabilistic Modelling of Domain and Gene Evolution

    Författare :Sayyed Auwn Muhammad; Jens Lagergren; Bastien Boussau; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phylogenetics; Phylogenomics; Evolution; Domain Evolution; Gene tree; Domain tree; Bayesian Inference; Markov Chain Monte Carlo; Homology Inference; Gene families; C2H2 Zinc-Finger; Reelin Protein; Computer Science; Datalogi;

    Sammanfattning : Phylogenetic inference relies heavily on statistical models that have been extended and refined over the past years into complex hierarchical models to capture the intricacies of evolutionary processes. The wealth of information in the form of fully sequenced genomes has led to the development of methods that are used to reconstruct the gene and species evolutionary histories in greater and more accurate detail.

  3. 2. Evolution of human alpha-herpesviruses

    Författare :Peter Norberg; Göteborgs universitet; []
    Nyckelord :HSV-1; HSV-2; VZV; evolution; recombination; phylogenetic analysis;

    Sammanfattning : Herpesviridae is a large virus family with more than 100 members, which are highly disseminated among animals. Three sub-families have been classified; alpha-herpesviruses, beta-herpesviruses and gamma-herpesviruses. LÄS MER

  4. 3. Computational Problems in Modeling Evolution and Inferring Gene Families

    Författare :Mehmood Alam Khan; Lars Arvestad; Jens Lagergren; Christophe Dessimoz; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Evolution; Phylogenetics; Lateral Gene Transfer; Gene Families; Clustering; Datalogi; Computer Science;

    Sammanfattning : Over the last few decades, phylogenetics has emerged as a very promising field, facilitating a comparative framework to explain the genetic relationships among all the living organisms on earth. These genetic relationships are typically represented by a bifurcating phylogenetic tree — the tree of life. LÄS MER

  5. 4. Reconciling gene family evolution and species evolution

    Författare :Joel Sjöstrand; Jens Lagergren; Nicolas Lartillot; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computational biology; Bioinformatics; Phylogenetics; Phylogenomics; Comparative genomics; Evolutionary biology; datalogi; Computer Science;

    Sammanfattning : Species evolution can often be adequately described with a phylogenetic tree. Interestingly, this is the case also for the evolution of homologous genes; a gene in an ancestral species may – through gene duplication, gene loss, lateral gene transfer (LGT), and speciation events – give rise to a gene family distributed across contemporaneous species.

  7. 5. Dwarf and Subgiant Stars as Probes of Galactic Chemical and Dynamical Evolution

    Författare :Patrik Thorén; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomy; Abundances; atomic data; Galactic evolution; late-type stars; main sequence stars; subgiants; Pop II; Pop I; stellar evolution; Astronomi; Astronomy and astrophysics; Astronomi och astrofysik; astronomi; Astronomy;

    Sammanfattning : Stellar chemical abundances provide astronomers with vital information about the production of chemical elements. Some stars preserve the composition of the environment in which they were born on their surfaces. LÄS MER
