  1. 1. Experimental Evolution : and Fitness Effects of Mutations

    Författare :Anna Knöppel; Dan I Andersson; Stanley Maloy; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Experimental evolution; Fitness effects; mutations; S20; fis; ribosome; horizontal gene transfer; adaptation; synonymous mutations; Mikrobiologi; Microbiology;

    Sammanfattning : Bacteria have small, streamlined genomes and evolve rapidly. Their large population sizes allow selection to be the main driver of evolution. With advances in sequencing technologies and precise methods for genetic engineering, many bacteria are excellent models for studying elementary questions in evolutionary biology. LÄS MER

  3. 2. Evolutionary trajectories of Klebsiella pneumoniae : From experimental biofilm evolution to a hospital outbreak

    Författare :Greta Zaborskytė; Linus Sandegren; Vaughn S. Cooper; Uppsala universitet; []
    Nyckelord :Klebsiella pneumoniae; evolution; experimental evolution; biofilms; infection; bacterial pathogens; Mikrobiologi; Microbiology;

    Sammanfattning : Bacterial evolution is closely intertwined with our lives. As their hosts, we shape how bacteria evolve by imposing numerous selective pressures during the time bacteria spend in our bodies. As a result, they adapt in various ways to colonize us or infect us better. LÄS MER

  4. 3. Adaptive divergence in fission yeast : From experimental evolution to evolutionary genomics

    Författare :Sergio Ivan Tusso Gomez; Jochen B.W. Wolf; Simone Immler; Roger K. Butlin; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; adaptation; divergence; selection; experimental evolution; genomics; genome evolution; population genetics; fission yeast; phenotypic variation; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : How adaptation and population differentiation occur is fundamental to understand the origin of biodiversity. Work in speciation alongside the increased ease of generating genomic data have allowed the exploration of genomic changes relevant to adaptation. LÄS MER

  5. 4. Experimental Evolution of Life-history : Testing the Evolutionary Theories of Ageing

    Författare :Hwei-yen Chen; Alexei Maklakov; Tracey Chapman; Uppsala universitet; []
    Nyckelord :senescence; ageing; longevity; mortality; experimental evolution; Caenorhabditis remanei; Biologi; Biology;

    Sammanfattning : Ageing reduces fitness, but how ageing evolves is still unclear. Evolutionary theory of ageing hinges on the fundamental principal that the force of natural selection declines with age. LÄS MER

  7. 5. Computational Protein Evolution : Modeling the Selectivity and Promiscuity of Engineered Enzymes

    Författare :Klaudia Szeler; Shina C. Lynn Kamerlin; Mikael Widersten; Maria Ramos; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; enzymes; kinetics; catalysis; density functional theory; empirical valence bond; diesters; evolution; promiscuity; Biokemi; Biochemistry;

    Sammanfattning : Enzymes are biological catalysts that significantly increase the rate of all biochemical reactions that take place within cells and are essential to maintain life. Many questions regarding their function remain unknown. LÄS MER
