  1. 1. Complex Trait Genetics : Beyond Additivity

    Författare :Simon Forsberg; Örjan Carlborg; Julien Ayroles; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; genetic interactions; epistasis; additivity; GWAS; vGWAS; Genetic mapping; yeast; Arabidopsis Thaliana; dog; Genetik; Genetics;

    Sammanfattning : The link between the genotype and the phenotype of an organism is immensely complex. Despite this it can, to a great extent, be captured using models that assume that gene variants combine their effects in an additive manner. This thesis explores aspects of genetics that cannot be fully captured using such additive models. LÄS MER

  3. 2. Genome Divergence in Progress - a population genetic analysis of the allopolyploid Arabidopsis suecica and its maternal parent A. thaliana

    Författare :Mattias Jakobsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cytogenetik; Genetik; cytogenetics; Genetics; sequence polymorphism; microsatellites; population structure; polyploidy; single origin; Arabidopsis thaliana; Arabidopsis suecica; genome evolution; evolutionary history; Plant genetics; Växtgenetik;

    Sammanfattning : The evolutionary history of the allotetraploid Arabidopsis suecica and its maternal parent Arabidopsis thaliana is analyzed in the thesis in terms of genetic variation in the natural populations of the two species. The earliest phase of the speciation event in which the genomes of A. thaliana and A. LÄS MER

  4. 3. Functional studies of plant hexokinases and development of genetic methods in the moss Physcomitrella patens

    Författare :Mikael Ulfstedt; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : In the field of biology, model systems are frequently used for practical reasons. Model organisms possess several features that make them easy to work with in a laboratory setting. In addition they usually have a host of established genetic tools that have been developed by the research community. LÄS MER

  5. 4. Molecular population genetics of inducible defense genes in Populus tremula

    Författare :Carolina Bernhardsson; Stefan Jansson; Santiago González-Martinez; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Populus; herbivore defense; adaptation; population genetics; population structure; association mapping; complex traits; evolutionär genetik; evolutionary genetics;

    Sammanfattning : Plant-herbivore interactions are among the most common of ecological interactions. It is therefore not surprising that plants have evolved multiple mechanisms to defend themselves, using both constitutive chemical and physical barriers and by induced responses which are only expressed after herbivory has occurred.

  7. 5. Genetic diversity and grain protein composition of tetraploid wheat (Triticum durum Desf) germplasm from Ethiopia

    Författare :Faris Hailu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The extent and patterns of genetic diversity in landraces of tetraploid wheat germplasm collected from major wheat-producing regions of Ethiopia were assessed with the use of agromorphological,phenol-qualitative traits, grain proteins and molecular markers. The extent of genetic erosion of landraces in tetraploid wheat germplasm from Ethiopia was also evaluated. LÄS MER
