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

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

    Sammanfattning : 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. LÄS MER

  4. 8. Life cycle and flowering time control in beet

    Författare :Pierre Pin; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Flowering plants switch from vegetative growth to flowering at specific points in time. This biological process is triggered by the integration of endogenous stimuli and environmental cues such as changes in day length and temperature. LÄS MER

  5. 9. Genomic studies of mating system variation in flowering plants

    Författare :Juanita Gutiérrez-Valencia; Tanja Slotte; Magne Friberg; Mario Vallejo-Marín; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mating system evolution; cross- and self-fertilization; distyly; supergenes; complex phenotypic polymorphism; convergent evolution; homostyly; loss-of-function mutation; intrasexual competition; pollen; purifying selection; Linum; Arabis alpina; Ecology and Evolution; ekologi och evolution;

    Sammanfattning : The striking diversity of reproductive strategies that flowering plants exhibit remains one of the most intriguing conundrums in evolutionary biology. Pollination-related traits and mating system strategies have a major impact on the processes shaping plant evolution through their effects on genetic diversity and selection. LÄS MER

  7. 10. Plant phenology in seasonal environments

    Författare :Elsa Fogelström; Johan Ehrlén; Johan P. Dahlgren; Arthur Weis; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Autumn phenology; Cardamine pratensis; evolutionary ecology; heritability; herbivore preference; fitness components; flowering time; growing season length; life-history; Lathyrus vernus; natural selection; population differentiation; phenology; spring phenology; Plant Ecology; växtekologi;

    Sammanfattning : Phenology, or the seasonal timing life-history events such as emergence, reproduction and senescence will determine the outcome of interactions between plants and both abiotic and biotic aspects of the environment. Such timing is therefore of utmost importance for plants in seasonal environments. LÄS MER
