  1. 1. Spikemoss patterns Systematics and historical biogeography of Selaginellaceae

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Stina Weststrand; Uppsala universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; classification; historical biogeography; lycophytes; nomenclature; phylogeny; Selaginella; Selaginellaceae; systematics; fylogeni; historisk biogeografi; klassifikation; lummerväxter; nomenklatur; Selaginella; Selaginellaceae; systematik; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Sammanfattning : Selaginellaceae, spikemosses, is a heterosporous plant family belonging to the lycophytes. With an estimated age of some 350 million years, the family is historically important as one of the oldest known groups of vascular plants. Selaginellaceae is herbaceous with a worldwide distribution. However, the majority of the ca. LÄS MER

  2. 2. Mine the Gaps Evolution of Eukaryotic Protein Indels and their Application for Testing Deep Phylogeny

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Pravech Ajawatanawong; Uppsala universitet.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; indel; insertion deletion; protein evolution; bioinformatics; non-bilateria; eukaryotes; phylogeny; Biologi med inriktning mot systematik; Biology with specialization in Systematics; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : Insertions/deletions (indels) are potentially powerful evolutionary markers, but little is known about their evolution and few tools exist to effectively study them. To address this, I developed SeqFIRE, a tool for automated identification and extraction of indels from protein multiple sequence alignments. LÄS MER

  3. 3. Inferring Ancestry Mitochondrial Origins and Other Deep Branches in the Eukaryote Tree of Life

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Ding He; Uppsala universitet.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular Phylogeny; Phylogenomics; Mitochondria; Eukaryote tree of life; Biologi med inriktning mot systematik; Biology with specialization in Systematics; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : There are ~12 supergroups of complex-celled organisms (eukaryotes), but relationships among them (including the root) remain elusive. For Paper I, I developed a dataset of 37 eukaryotic proteins of bacterial origin (euBac), representing the conservative protein core of the proto-mitochondrion. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Amomum; Zingiberaceae; Flore du Cambodge du Laos et du Vietnam; Taxonomy; Ethnobotany; Postpartum; Mother roasting; Hotbed; Brou; Saek; Kry; Lao PDR; NATURAL SCIENCES Biology Organism biology; NATURVETENSKAP Biologi Organismbiologi; NATURAL SCIENCES Biology Organism biology Systematics and phylogenetics; NATURVETENSKAP Biologi Organismbiologi Systematik och fylogeni; Biologi med inriktning mot systematik; Biology with specialization in Systematics;

    Sammanfattning : The species of Amomum Roxb. (Zingiberaceae) in Cambodia, Laos and Vietnam are revised. Thirty-five species and two varieties are recognised, all names are typified, and detailed descriptions and a key are provided. Nine new species are described and one species is validated. LÄS MER

  5. 5. Contributions to the understanding of diversity and evolution in the genus Coreomyces

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Henrik Sundberg; Uppsala universitet.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ascomycetes; Coreomyces; Corixidae. DNA; DNA extraction; Fungi; ge-nome; host specificity; Laboulbeniales; mating types; MAT-loci; meth-odology; NGS; parasite; position specificity; systematics; taxonomy; Biology with specialization in Systematics; Biologi med inriktning mot systematik; Biology with specialization in Evolutionary Organismal Biology; Biologi med inriktning mot evolutionär organismbiologi;

    Sammanfattning : The Laboulbeniales is an order of enigmatic ascomycete fungi that are obligate microscopic parasites of arthropods, which are usually non-detrimental. They typically display a high degree of host specificity, and the genus Coreomyces, which is the recurring theme of this thesis, is no exception. LÄS MER
