  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. Using systems genetics to explore the complexity of leaf shape variation in Populus tremula

    Författare :Barbara Terebieniec; Nathaniel Street; Chung-Jui Tsai; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Populus; Arabidopsis; systems biology; systems genetics; spatial transcriptomics ST ; single nucleotide polymorphism SNP ; Genome wide associations study GWAS ; expression GWAS eGWAS ; molekylärbiologi; Molecular Biology;

    Sammanfattning : Leaves are essential for sustaining humanity as they function as the energy and oxygen-producing organ of plants. Intensive research on physiological processes has contributed immensely to our understanding of the function of leaves. However, comparatively little is known about how leaf size and shape is determined. LÄS MER

  5. 4. Sequence evolution in a chromosomal region of Arabidopsis thaliana

    Författare :Jenny Hagenblad; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtgenetik; Plant genetics; flowering time; mapping; polymorphism; Linkage disequilibrium; Arabidopsis thaliana;

    Sammanfattning : Recently there has been a lot of interest in the use of liknage disequilibrium (LD) in genome wide scans for new genes, so called association mapping. Of crucial importance to a genome wide scan for associations between genetic markers and the trait of interest is the extent of LD, as it determines both how closely a trait can be mapped and also how many markers is needed to map it.

  7. 5. Evolutionary consequences of dominance at the Brassicaceae self-incompatibility locus

    Författare :Jörg Alexander Bachmann; Tanja Slotte; Vincent Castric; Ove Eriksson; Pär Ingvarsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Capsella; mating system shift; self-fertilization; self-incompatibility; small RNA; dominance; Arabidopsis; population genetics; genomics; gene expression; ekologi och evolution; Ecology and Evolution;

    Sammanfattning : Self-incompatibility (SI) is a genetic mechanism that allows plants to enforce outcrossing by rejecting self-pollen and pollen from close relatives. In the Brassicaceae, SI is sporophytic and controlled by the self-incompatibility locus (S-locus). LÄS MER
