  1. 16. Genetic and epigenetic mechanisms underlying the regulation of flowering time

    Författare :Lejon Kralemann; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Developmental transitions and responses to the environment have a tight epigenetic control. Especially the switch to flowering is important for plants because it allows (sexual) reproduction, and should not occur unless the conditions are right. LÄS MER

  3. 17. Molecular Regulation of Bud Phenology and Vegetative Phase Change in Populus Trees

    Författare :Shashank Sane; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Trees are sessile organisms that have evolved to survive and thrive in changing growth conditions. As a survival strategy they undergo massive morphological changes that can be quantified. LÄS MER

  4. 18. Regulation of organ development by auxin and the SHI/STY-family of transcriptional regulators

    Författare :Veronika Nordal; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Transcription factors, proteins regulating the transcription of target genes, and plant hormones play important roles in the regulation of plant development. The plant hormone auxin has been assigned functions in many developmental processes and its differential distribution between cells, created mainly by local auxin biosynthesis and polar auxin transport, results in auxin maxima and gradients, which appear to be important for its role in developmental regulation.

  5. 19. Developmental phase transitions in Norway spruce : a molecular approach to identify regulatory mechanisms

    Författare :Daniel Uddenberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Plant development proceeds through distinct phases that are controlled by complex networks of regulatory genetic circuits and fine-tuned by environmental and endogenous cues. Many of these regulatory networks have been unraveled in annual and perennial angiosperms, while they remain predominantly unknown in ecologically and economically important gymnosperm species such as the conifers.

  7. 20. The molecular mechanisms behind perception and signal transduction of UV-B irradiation in Arabidopsis thaliana

    Författare :Irina Kalbina; Åke Strid; Lars-Gunnar Franzén; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Action spectroscopy; Arabidopsis; gene expression; reverse genetics; signal transduction; UV-B irradiation.; Biochemistry; Biokemi; Biochemistry; Biokemi;

    Sammanfattning : Elevation of UV-B radiation (280-315 nm), occurring as a result of depletion of the stratospheric ozone, causes a number of physiological and biochemical changes in plants. Damage to the photosynthetic apparatus (including the bleaching of the pigments which trap the sun's energy), to the processes of cell division and growth regulation, and to the composition and replication of genetic material are just some of these changes.
