  1. 1. Genetic Analysis of Cytosolic PGI in Festuca ovina

    University dissertation from Lena Ghatnekar, Dept. of Cell and Organism Biology, Lund University, Sweden

    Author : Lena Ghatnekar; Lund University.; Lunds universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Växtgenetik; Plant genetics; pseudogenes; grasses; cytosolic PGI; introgression; duplication; Festuca ovina;

    Abstract : Festuca ovina, sheep's fescue is a widely distributed perennial outbreeder that belongs to the grass family Poaceae and is very common in the northern temperate zone. The genus Festuca s.l. is partitioned into fine-leaved fescues to which F. READ MORE

  2. 2. Sequence evolution in a chromosomal region of Arabidopsis thaliana

    University dissertation from Jenny Hagenblad, Genetics, Sölvegatan 29, 22362 Lund, Sweden

    Author : Jenny Hagenblad; Lund University.; Lunds universitet.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Växtgenetik; Plant genetics; flowering time; mapping; polymorphism; Linkage disequilibrium; Arabidopsis thaliana;

    Abstract : Recently there has been a lot of interest in the use of liknage disequilibrium (LD) in genome wide scans for new genes, so called association mapping. Of crucial importance to a genome wide scan for associations between genetic markers and the trait of interest is the extent of LD, as it determines both how closely a trait can be mapped and also how many markers is needed to map it.

  3. 3. Genome Divergence in Progress - a population genetic analysis of the allopolyploid Arabidopsis suecica and its maternal parent A. thaliana

    University dissertation from Mattias Jakobsson, Dept. of COB, Genetics, Lund University

    Author : Mattias Jakobsson; Lund University.; Lunds universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cytogenetik; Genetik; cytogenetics; Genetics; sequence polymorphism; microsatellites; population structure; polyploidy; single origin; Arabidopsis thaliana; Arabidopsis suecica; genome evolution; evolutionary history; Plant genetics; Växtgenetik;

    Abstract : The evolutionary history of the allotetraploid Arabidopsis suecica and its maternal parent Arabidopsis thaliana is analyzed in the thesis in terms of genetic variation in the natural populations of the two species. The earliest phase of the speciation event in which the genomes of A. thaliana and A. READ MORE

  4. 4. Geographic Variation, Hybridization and Evolution in the Bladder Campions, Silene vulgaris and S. uniflora (Caryophyllaceae)

    University dissertation from Department of Ecology, Lund University

    Author : Eva Månsby; Lund University.; Lunds universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chemotaxonomy.

Växters fysiologi inte kärlväxter .;

    Abstract : In the present thesis, I investigated the inter- and intraspecific variation in the Silene vulgaris/uniflora species-complex (the bladder campions). I have focused on the effects of past and present hybridization both on a large scale ? over the whole of Europe ? and on a local scale. Silene vulgaris and S. READ MORE

  5. 5. Temperature effects on UV-B induced DNA damage and repair in plants and a lichen

    University dissertation from Markus Paulsson, Sölvegatan 35, SE-223 62 Lund, Sweden

    Author : Markus Paulsson; Lund University.; Lunds universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tobacco Nicotiana tabacum ; Temperature; Subarctic; Plants; Photoreactivation; Photolyase; Lichen; DNA damage; Cyclobutane pyrimidine dimers CPD ; 6-4 Photoproducts; Cladonia arbuscula ssp. mitis; Ultraviolet radiation; UV-B; Vaccinium vitis-idaea; Plant genetics; Växtgenetik;

    Abstract : All living organisms have DNA and since DNA is essential to life it must be repaired when damaged. UV radiation is one of the major DNA damaging agents, which photosynthetic organisms cannot avoid. READ MORE
