  1. 21. Phylogenetic Support and Chloroplast Genome Evolution in Sileneae (Caryophyllaceae)

    Författare :Per Erixon; Bengt Oxelman; Sean Graham; Uppsala universitet; []
    Nyckelord :Biology; Phylogenetics; Bayesian inference; Bootstrapping; cpDNA; Sileneae; Interspecific chloroplast recombination; Hybridization; clpP; Positive selection; Extreme substitution rates; Biologi;

    Sammanfattning : Evolutionary biology is dependent on accurate phylogenies. In this thesis two branch support methods, Bayesian posterior probablities and bootstrap frequencies, were evaluated with simulated data and empirical data from the chloroplast genome. LÄS MER

  3. 22. The chloroplast lumen proteome of Arabidopsis thaliana

    Författare :Maria Schubert; Wolfgang Schröder; Eva-Maria Aro; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photosynthesis; chloroplast; thylakoid lumen; Arabidopsis thaliana; proteome;

    Sammanfattning : In plants, the chloroplast organelles host the photosynthetic machinery, which catalyzes the conversion of light energy to chemical energy used for synthesis of carbohydrates. Inside the chloroplast, the lumen compartment forms an integral part of the thylakoid network that performs the light reactions of photosynthesis. LÄS MER

  4. 23. Evolutionary history and chloroplast DNA variation in three plant genera: Betula, Corylus and Salix. : The impact of post-glacial colonisation and hybridisation

    Författare :Anna Palmé; Andrew Lowe; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; chloroplast DNA; phylogeography; hybridization; phylogeny; Salix caprea; Betula pendula; Corylus avellana; Biologi; Biology; Biologi; naturvårdsbiologi; Conservation Biology;

    Sammanfattning : The great difference in the level of chloroplast variation and its geographic structure among the three main species studied here demonstrates that forest species do not form a homogeneous group. Hazel shows a genetic structure similar to many other thermophilous species and this structure, in combination with fossil evidence, indicates that the post-glacial colonisation of most of Europe originated in a refugium in western France while the Balkan and Italy were colonised from a south-eastern refugium.

  5. 24. Peptidyl-prolyl cis-trans Isomerases in the Chloroplast Thylakoid Lumen

    Författare :Anna Edvardsson; Alexander Vener; Bertil Andersson; Per Gardeström; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Peptidyl-prolyl isomerase activity; Cyclophilin; FKBP; Immunophilin; Chloroplast Thylakoid Lumen; protein characterization; Medical cell biology; Medicinsk cellbiologi;

    Sammanfattning : The Sun is the ultimate energy source on Earth. Photosynthetic organisms are able to catalyze the conversion of solar energy to chemical energy by a reaction called photosynthesis. In plants, this process occurs inside a green organelle called the chloroplast. LÄS MER

  7. 25. 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
