  2. 11. Cytogenetics, genetic diversity and phylogenetics of wild Zea species, with emphasis on Zea nicaraguensis

    Author : Carlos Henry Loáisiga Caballero; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Maize (Zea mays subsp. mays) is a member of the grass family Poaceae (Gramineae), together with many other important agricultural crops. The wild species commonly known as teosintes are the closest relatives of maize. READ MORE

  4. 12. Expression and function of Suppressor of zeste 12 in Drosophila melanogaster

    Author : Sa Chen; Åsa Rasmuson-Lestander; Jan Larsson; Mattias Mannervik; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Epigenetics; histone; polycomb; Drosophila; Suppressor of zeste 12; Genetics; Genetik; genetik; Genetics;

    Abstract : The development of animals and plants needs a higher order of regulation of gene expression to maintain proper cell state. The mechanisms that control what, when and where a gene should (or should not) be expressed are essential for correct organism development. READ MORE

  5. 13. Molecular Evolution of the Vertebrate Genome

    Author : Kiwoong Nam; Hans Ellegren; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis, I studied molecular evolution of the vertebrate genome, focusing on sex chromosomes, protein coding genes, and genome size variation. The evolutionary history of avian sex chromosomes was analyzed by comparing substitution rate among 12 gametologous gene pairs on the Z and W chromosomes. READ MORE

  6. 14. Speciation genomics in Ficedula flycatchers

    Author : Madeline Chase; Carina Mugal; Chris Jiggins; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; recombination; linked selection; selective sweeps; sex chromosomes; structural variation; birds; genome assembly; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Understanding what evolutionary processes have shaped patterns of genomic differentiation between species is a major aim of speciation genomics. However, disentangling the role of different processes that generate similar patterns remains a substantial challenge. READ MORE

  7. 15. Genetic Mapping of Susceptibility Genes for Systemic Lupus Erythematosus

    Author : Bo Johanneson; Jean Pierre Hugot; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular genetics; Association analysis; Candidate gene; Complex disease; Genome scan; Linkage analysis; Mapping; Susceptibility genes; Systemic lupus erythematosus; Genetik; Genetics; Genetik; medicinsk genetik; Medical Genetics;

    Abstract : Systemic lupus erythematosus (SLE) is a complex autoimmune disease with unknown etiology. The aim of this thesis was to identify susceptibility regions through genetic mapping, using model-based linkage analysis on nuclear and extended SLE multicase families. READ MORE
