    Sammanfattning : Large-scale patterns of genetic variation in chloroplast (cp) and nuclear DNA in the widespread European herb species Silene latifolia and S. dioica were investigated using cpPCR-RFLPs, non-coding cpDNA sequences, AFLPs and sequences of the internal transcribed spacers (ITS) of nuclear ribosomal DNA (rDNA).

  3. 2. Mechanisms of speciation in Silene

    Författare :Xiaodong Liu; Sophie Karrenberg; Alex Buerkle; Uppsala universitet; []
    Nyckelord :speciation; reproductive isolation; Silene; ddRAD-seq; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : A fundamental question in the field of evolutionary biology is how new species originate. Investigating speciation benefits from an integrated approach, which requires a solid understanding of ecology, reproductive biology, geographical distribution, underlying genetic architecture of reproductive isolation (RI), demographic history and genomic divergence.

  4. 3. Phylogenetic Relationships of Silene sect. Melandrium and Allied Taxa (Caryophyllaceae), as Deduced from Multiple Gene Trees

    Författare :Anja Rautenberg; Bengt Oxelman; Mikael Thollesson; Magnus Lidén; Freek Bakker; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Silene; Elisanthe; Melandrium; Conoimorpha; Caryophyllaceae; Silene multinervia; relative dating; extreme substitution rates; phylogeny; BEST; BEAST; cpDNA; mtDNA; RNA polymerase; RPA2; RPB2; RPD2; SlX1; SlY1; ITS; introgression; incongruent phylogenies; chromosome count; coalescent; Bayes Factors; Systematics and phylogenetics; Systematik och fylogeni; systematisk botanik; Systematic Botany;

    Sammanfattning : This thesis focuses on phylogenetic relationships among some of the major lineages in Silene subgenus Behenantha (Caryophyllaceae) using DNA sequences from multiple, potentially unlinked gene regions from a large taxonomic and geographic sample. Both traditional phylogenetic analyses and a strategy to infer species trees and gene trees in a joint approach are used. LÄS MER

  5. 4. Geographic differentiation and population history in Silene dioica and S. hifacensis: variation in chloroplast DNA and allozymes

    Författare :Ursula Malm; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; morphology; taxonomy; Systematic botany; conservation biology; endemic; chloroplast DNA; allozyme; hybridization; gene flow; geographic variation; postglacial migration; genetic diversity; Silene; phytogeography; chemotaxonomy. Physiology of nonvascular plants; Systematisk botanik; taxonomi; morfologi; kemotaxonomi. Växters fysiologi inte kärlväxter .;

    Sammanfattning : In this thesis I used allozymes and PCR-RFLP analysis of chloroplast DNA (cpDNA) to investigate geographic differentiation within the widespread Silene dioica (L.) Clairv. (Caryophyllaceae) and the narrowly-distributed S. hifacensis Rouy ex Willk. LÄS MER
