  1. 11. Variational methods for phylogeny and single-cell genomics

    Författare :Hazal Koptagel; Jens Lagergren; Alexandre Bouchard-Côté; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Variational inference; single-cell DNA sequencing; cell lineage tree; Bayesian phylogenetic tree inference; Variationsinferens; encellig DNA-sekvensering; cellhärkomstträd; Bayesiansk fylogenetisk trädinferens; Varyasyonel çıkarım; tek hücre DNA dizilimi; hücre soy ağacı; Bayesçi filogenetik ağaç çıkarımı; Datalogi; Computer Science;

    Sammanfattning : The investigation of the evolutionary history of organisms, both at the cellular level and at the species level, is a relevant research topic in computational biology. These investigations lead to a deeper understanding of developmental history, cancer progression, the genetic similarity of species, and more. LÄS MER

  3. 12. Evolutionary transitions across the tree of life : Phylogenomic case studies in environmental archaea, bacteria and eukaryotes

    Författare :Max Emil Schön; Thijs J. G. Ettema; Fabien Burki; David Moreira; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Evolutionary transitions; environmental sequencing; metagenomics; single-cell genomics; phylogenomics; haloarchaea; Hikarchaeia; Rickettsiales; Picozoa; plastid evolution; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : Microbes form the majority of life on Earth, but have been systematically underrepresented in historical research. The sequencing revolutions of the last two decades have completely changed the way we can study microbial genomic information, giving us the means to probe ever deeper into their evolution. LÄS MER

  4. 13. Taking advantage of phylogenetic trees in comparative genomics

    Författare :Örjan Åkerborg; Jens Lagergren; Mathieu Blanchette; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Bioinformatics; Bioinformatik;

    Sammanfattning : Phylogenomics can be regarded as evolution and genomics in co-operation. Various kinds of evolutionary studies, gene family analysis among them, demand access to genome-scale datasets. But it is also clear that many genomics studies, such as assignment of gene function, are much improved by evolutionary analysis. LÄS MER

  5. 14. Phylogenetic studies in the Inuleae s. lat. (Asteraceae)

    Författare :Pia Eldenäs; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; Plant Systematics; växtsystematik;

    Sammanfattning : This thesis concerns phylogenetic problems in the tribe Inuleae s. lat. (Asteraceae). The genus Perralderia is revised. LÄS MER

  7. 15. Phylogenetic and taxonomic studies within Arthonia Ach. (Ascomycetes, Arthoniales)

    Författare :Rikard Sundin; Jan-Eric Mattsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systematics and phylogenetics; Systematik och fylogeni; Plant Systematics; växtsystematik;

    Sammanfattning : The taxonomy and phylogeny of the genus Arthonia was analysed. As a first step, a phylogenetic analysis was performed to test the monophyly of some of the infrageneric groups suggested by earlier authors. The results strongly support that Arthonia, Arthothelium and Arthoniaceae are paraphyletic. LÄS MER
