  1. 1. Population Genetics of Human Genomic Elements

    Författare :Thijessen Naidoo; Mattias Jakobsson; Guillaume Achaz; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; population genetics; human genome; functional elements; natural selection; pseudogenes; loss-of-function; gene regulation; Y chromosome; Biology with Specialisation in Human Evolution and Genetics; Biologi med inriktning mot människans evolution och genetik;

    Sammanfattning : The genomes of living organisms are composed of a multitude of functional units, which interact with each other and their environment in a highly regulated fashion, to facilitate the expression of an enduring (and evolving) phenotype. Several approaches have emerged in the effort to identify these functional units and explore their activities. LÄS MER

  2. 2. Genetic Analysis of Cytosolic PGI in Festuca ovina

    Författare :Lena Ghatnekar; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtgenetik; Plant genetics; pseudogenes; grasses; cytosolic PGI; introgression; duplication; Festuca ovina;

    Sammanfattning : Festuca ovina, sheep's fescue is a widely distributed perennial outbreeder that belongs to the grass family Poaceae and is very common in the northern temperate zone. The genus Festuca s.l. is partitioned into fine-leaved fescues to which F. LÄS MER

  3. 3. Probabilistic Reconciliation Analysis for Genes and Pseudogenes

    Författare :Owais Mahmudi; Jens Lagergren; Cedric Chauve; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Phylogenetics; Evolution; Reconciliation Analysis; Bayesian Inference; Computer Science; Datalogi;

    Sammanfattning : Phylogeneticists have studied the evolution of life from single celled organisms to the astonishing biodiversity around us for a long time now. The relationship between species is often expressed as a binary tree - the tree of life. LÄS MER

  4. 4. Molecular evolutionary studies of genome degradation in bacteria

    Författare :Jan O. Andersson; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : The genus Rickettsia belongs to the α-proteobacteria and consists of obligate intracellular bacteria, which often are pathogenic for humans. All Rickettsia have small genomes, highly adapted to an intracellular lifestyle. LÄS MER

  5. 5. Causes of Substitution Frequency Variation in Pathogenic Bacteria

    Författare :Wagied Davids; Siv Andersson; Otto Berg; Bengt Persson; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Biology; Comparative genomics; Molecular evolution; Bioinformatics; Human pathogens; Rickettsia; Helicobacter pylori; Biologi; Biology; Biologi;

    Sammanfattning : Estimating substitution frequencies at sites that influence (Ka) and do not influence (Ks) the amino acid sequence is important for understanding the dynamics of molecular sequence evolution and the selective pressures that have shaped genetic variation. The aim of this work was to gain a deeper understanding of the driving forces of substitution frequency variation in human pathogens. LÄS MER
