  1. 1. Phylogenetic Inference and Allopolyploid Speciation - A Study of Silene section Physolychnis

    Författare :Anna Petri; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; allopolyploidization; next-generation sequencing; Physolychnis; sequence specific primers; Silene; species networks; transcriptomics;

    Sammanfattning : The major theme of this thesis is allopolyploidization, with focus on Silene section Physolychnis. The evolutionary history of an allopolyploid species can be established by inferring the sister relationships of the homoeologous sequences from low copy nuclear markers. LÄS MER

  3. 2. Bridging the past to the present: investigating species boundaries with herbarium specimens and next-generation-sequencing. A case study of circumpolar Silene sect. Physolychnis

    Författare :Anne-Sophie Quatela; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; allele phasing; Bayesian inference; herbarium specimen; long read sequencing; multispecies coalescent; Silene; systematics; target capture; species complexes;

    Sammanfattning : During the recent decades, genetic information enclosed in herbarium collections have been partly revealed, largely due to the fast-moving high-throughput sequencing technologies. However, the genetic outcome from herbarium material is limited by its degradation over time, often worsened by certain preservation methods. LÄS MER
