  4. 2. Effects of increased UV-B radiation on the lichen Cladonia arbuscula spp. mitis: UV-absorbing pigments and DNA damage

    Author : Roberta Buffoni Hall; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Systematic botany; taxonomy; morphology; phytogeography; chemotaxonomy. Physiology of nonvascular plants; kemotaxonomi. Växters fysiologi inte kärlväxter .; Systematisk botanik; taxonomi; morfologi;

    Abstract : Lichens, a form of symbiosis between a fungal and a photosynthetic partner, are believed to be a group that evolved early in the history of terrestrial life. As a consequence, they probably experienced higher ultraviolet (UV) radiation fluxes than at present. READ MORE

  5. 3. Patterns of geographic variation in Silene section Elisanthe (Caryophyllaceae): hybridization and migrational history

    Author : Louise Hathaway; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chemotaxonomy. Physiology of nonvascular plants; phytogeography; morphology; outbreeding depression; Systematic botany; taxonomy; ITS; fitnes; inbreeding depression; AFLP; PCR-RFLP; cpDNA; gene flow; postglacial migration; geographic variation; hybridization; Silene latifolia; Silene section Elisanthe; Silene dioica; Systematisk botanik; taxonomi; morfologi; kemotaxonomi. Växters fysiologi inte kärlväxter .;

    Abstract : 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).

  6. 4. Diversity and phylogeography in Alisma (Alismataceae), with emphasis on Northern European taxa

    Author : Anders Jacobson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; morphology; phytogeography; chemotaxonomy. Physiology of nonvascular plants; taxonomy; Systematic botany; Baltic Sea; Europe; refugia; post-glacial migration; phylogeography; marsh plants; genetic variation; aquatic plants; Alisma; Systematisk botanik; taxonomi; morfologi; kemotaxonomi. Växters fysiologi inte kärlväxter .;

    Abstract : In the present thesis the phylogeny and patterns of genetic diversity of the plant genus Alisma (Alismataceae) were investigated by means of genetic markers (RAPDs, allozymes, and ITS and trnL sequences). Additionally, morphological studies were carried out in paper IV. READ MORE

  7. 5. Gene description, activity quantification and physiological responses of mitochondrial alternative NAD(P)H dehydrogenases

    Author : Fredrik Johansson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; phytogeography; chemotaxonomy. Physiology of nonvascular plants; Systematisk botanik; taxonomi; morfologi; kemotaxonomi. Växters fysiologi inte kärlväxter .; morphology; taxonomy; Systematic botany; plant mitochondria; NAD P H dehydrogenases; cold treatment; complex I; light dependence; antimycin a; alamethicin;

    Abstract : In addition to proton-pumping complex I, the plant respiratory chain contains type II NAD(P)H dehydrogenases. These extra enzymes do not pump protons and consequently do not contribute to the electrochemical proton gradient. READ MORE
