  1. 1. 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

  3. 2. Towards spatial host-microbiome profiling

    Författare :Britta Lötstedt; Joakim Lundeberg; Petri Auvinen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 16S sequencing; RNA sequencing; spatially resolved transcriptomics; antibody-based measurements; Bioteknologi; Biotechnology;

    Sammanfattning : Sequencing technologies and applications have pushed the limits and enabled novel studies of biological mechanisms, evolutionary relationships and communication networks between cells. The technical developments leading to single cell RNA-sequencing have enabled detection of rare cell populations while spatial resolution added insights into larger biological environments, like tissues and organs.

  4. 3. Functional organisation of the cell nucleus in the fission yeast, Schizosaccharomyces pombe

    Författare :Jenny Alfredsson Timmins; Pernilla Bjerling; Wendy Bickmore; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fission yeast; heterochromatin; subnuclear organisation; chromo domain proteins; boundary elements; transcriptional regulation; epigenetics; Molecular biology; Molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; Genetics; Genetik; Molecular Biology; molekylärbiologi; Genetics; genetik;

    Sammanfattning : In eukaryotes the genome adopts a non-random spatial organisation, which is important for gene regulation. However, very little is known about the driving forces behind nuclear organisation. LÄS MER

  5. 4. From the migrations of herders and farmers to the colonial era and the modern-day : Genetic inferences on African demographic history

    Författare :Rickard Hammarén; Mattias Jakobsson; Carina Schlebusch; Torsten Günther; Luca Pagani; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; admixture; African demography; human evolutionary genetics; population structure; sex-biased admixture; Africa; population genetics; Biology with Specialisation in Human Evolution and Genetics; Biologi med inriktning mot människans evolution och genetik;

    Sammanfattning : Africa is the birthplace of the human species and home to great linguistic, cultural, and genetic diversity. Despite this, the genetics of the peoples of the continent remains understudied. In this thesis, I apply population genetic approaches, to contribute to the knowledge of human demographic history in Africa. LÄS MER

  7. 5. Quantitative genetics of Norway spruce in Sweden

    Författare :Zhiqiang Chen; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Genetic improvement of solid wood and pulp and paper products related wood quality traits are important to increase productivity and value of Norway spruce plantation in Sweden. To incorporate wood quality traits into Norway spruce tree breeding program, genetic parameters of solid wood and fibre traits were investigated in a large Norway spruce population. LÄS MER
