  1. 6. Control of Pistil Development in Arabidopsis thaliana by a Novel Class of Regulatory Genes

    Författare :Sandra Kuusk; Eva Sundberg; John Bowman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; Biology; Biologi; fysiologisk botanik; Physiological Botany;

    Sammanfattning : The pistil, or the gynoecium, is the female reproductive organ of the angiosperm flower and its ontogeny has been studied in the model plant Arabidopsis thaliana. The mature Arabidopsis gynoecium consists of a basal ovary that contains the ovules, a short style and an apical stigma that serves as the site of pollen adherence and germination. LÄS MER

  3. 7. Changes in the transcriptome and metabolome during the initiation of growth cessation in hybrid aspens

    Författare :Daniel Hoffman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : At 9 550 years of age, Old Rasmus, a Norway spruce (Picea abies), located in the Dalarna province in Sweden is recognized as the oldest surviving tree in the world. Old Rasmus exemplifies a robust capacity to survive in changing conditions, making trees a unique and fascinating subject for study. LÄS MER

  4. 8. A genetic approach to the identification of new components regulating development in Arabidopsis thaliana

    Författare :Ingela Fridborg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; fysiologisk botanik; Physiological Botany;

    Sammanfattning : Two new genes involved in important processes of plant development were identified in the model plant Arabidopsis thaliana. The genes were isolated from mutants generated through insertional mutagenesis based on a transposon tagging approach. LÄS MER

  5. 9. Evolution of Flowering Time in the Tetraploid Capsella bursa-pastoris (Brassicaceae)

    Författare :Tanja Slotte; Martin Lascoux; Ulf Lagercrantz; Juliette de Meaux; Uppsala universitet; []
    Nyckelord :Biology; flowering time; homoeolog; hybridization; introgression; microarray; multiple origins; polyploid; QTL; Biologi;

    Sammanfattning : Although polyploidy is believed to be a major source of evolutionary novelty, few studies have examined the genetic basis of phenotypic variation in wild polyploids. In this thesis I have studied the genetic basis of flowering time variation in the wild tetraploid crucifer Capsella bursa-pastoris, as well as the evolutionary history of this species. LÄS MER

  7. 10. Population management of cone and seed insects in spruce seed orchards

    Författare :Olle Rosenberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Seed orchards have been established in order to produce high quality seeds for reforestation and forestation. However, seed production in spruce (Picea abies (L.) Karst.) seed orchards is severely hampered by cone- and seed-feeding insects. LÄS MER
