  1. 1. Taxonomy and Reticulate Phylogeny of Heliosperma and Related Genera (Sileneae, Caryophyllaceae)

    Författare :Božo Frajman; Bengt Oxelman; Mats Thulin; Christian Brochmann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sileneae; Silene; Heliosperma; Atocion; Viscaria; taxonomy; phylogenetics; relative dating; reticulate evolution; chloroplast capture; homoploid hybridisation; BEAST; r8s; PATHd8; Prometheus; RPA2; RPB2; RPD2a; RPD2b; Balkan Peninsula; endemics; Systematics and phylogenetics; Systematik och fylogeni;

    Sammanfattning : Heliosperma (nom. cons prop.) comprises 15—20 taxa, most of them endemic to the Balkan Peninsula. DNA sequences from the chloroplast (rps16 intron, psbE-petG spacer) and the nuclear genome (ITS and four putatively unlinked RNA polymerase genes) are used to elucidate phylogenetic relationships within Heliosperma, and its position within Sileneae.

  3. 2. Genetic diversity and differentiation in natural and managed stands of Norway spruce (Picea abies)

    Författare :Helena Eklöf; Pär K. Ingvarsson; Xiao-Ru Wang; Carolina Bernhardsson; Katri Kärkkäinen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Norway spruce; Picea abies; forestry; genetic diversity; seed orchards; forest management; WGS; GBS; sequencing; PoolSeq; capture probes; genetic differentiation;

    Sammanfattning : Being one of Sweden’s most important tree species, both as a keystone species and for the forest industry, it is important that we keep our stands of Norway spruce (Picea abies (L.) Karst.) as healthy as possible. LÄS MER

  4. 3. Single-cell methodologies for ecological and metabolic mapping of mixotrophic microeukaryotes

    Författare :Javier Florenza; Stefan Bertilsson; Alexandra Z. Worden; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; mixotrophy; single-cell;

    Sammanfattning : Mixotrophy in aquatic protists is pivotal for our understanding of aquatic microbial food web dynamics. This thesis is centered around aquatic unicellular mixotrophs, and comprises three methodological approaches aimed to tackle mixotroph ecology at single-cell resolution: the identification of actively feeding mixotrophs in natural samples, the determination of specific interactions among mixotrophs and bacterial prey, and the profiling of two distinct mixotrophic populations based on the gene expression of their constitutive individuals.

  5. 4. Interactions Between Small Heat Shock Proteins and Substrate Proteins Mass Spectrometric Detection of Crosslinked Peptides to Map Protein-Protein Interactions

    Författare :Emma Åhrman; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein-protein interactions; Small heat shock proteins; Mass spectrometric peptide mapping; Proteins; enzymology; Proteiner; enzymologi;

    Sammanfattning : The small heat shock proteins (sHsps) are a widespread class of molecular chaperones existing in all organisms. During heat stress the sHsps protect other proteins from unfolding and aggregation. In plants the sHsps play an especially prominent part of the stress response. LÄS MER

  7. 5. Next-generation Molecular Systematics and Evolution: insights into Medicago

    Författare :Filipe de Sousa; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phylogeny; incomplete lineage sorting; paralogy; hybridisation; Medicago;

    Sammanfattning : Evolutionary relationships among species have in recent years been inferred using DNA sequences from specific genes and represented by tree diagrams (phylogenies). However, the signal contained in different genes can produce conflicting sets of relationships – i.e., gene tree incongruence. LÄS MER
