  2. 1. From QTLs to Genes: Flowering Time Variation and CONSTANS-LIKE Genes in the Black Mustard (Brassica nigra)

    Author : Marita Kruskopf Österberg; Martin Lascoux; Ulf Lagercrantz; Thomas Bataillon; Uppsala universitet; []
    Keywords : Molecular genetics; Flowering time; Brassica nigra; CONSTANS; CONSTANS-LIKE 1; Genetik;

    Abstract : The transition to flowering is a major developmental switch in angiosperms, the timing of which is expected to be important for fitness. In this thesis the focus has been on identification of genes affecting natural variation in flowering time in Brassica nigra. The background for this thesis is an earlier QTL-mapping study in B. nigra. READ MORE

  4. 2. Black mustard and the butterfly effect : metabolomics of plant-insect interactions under multiple stress conditions

    Abstract : One main goal of ecological research is to understand nature´s complexity, in order to predict the potential impact of environmental perturbations. In this thesis, I investigate the ecological interactions between some of the most ancient organisms living on our planet: plants and insects. READ MORE

  5. 3. Effects of Selection and Demography on DNA Polymorphism in Black Mustard (Brassica nigra)

    Author : Per Sjödin; Martin Lascoux; Ulf Lagercrantz; Mikkel Schierup; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular genetics; population genetics; Genetik; Genetics; Genetik;

    Abstract : The evolution of three genes from the CONSTANS-LIKE gene family is studied in Brassica nigra. We use a combination of population genetic and phylogenetic techniques in order to assess the relative importance of selection and demography on the pattern of DNA variation. READ MORE
