21. Novel insights into the action of SHI/STY transcriptional regulators during plant development
Sammanfattning : One key player in plant organogenesis is the phytohormone auxin, and this thesis reveal that members of the SHI/STY gene family participate in the regulation of auxin homeostasis and organ development in Arabidopsis thaliana. Using inducible constructs, ChIP, and EMSA, we could show that the SHI/STY members act as transcriptional activators directly binding to the promoter of the auxin biosynthesis gene YUC4. LÄS MER
22. Signalling mechanisms and epigenetic regulation of seed development in Arabidopsis thaliana
Sammanfattning : In flowering plants, seed development starts with a double fertilisation event, leading to the formation of the embryo and the endosperm. Though only the embryo contributes to the next generation, control of endosperm proliferation, as well as the timing of its cellularisation are crucial for embryo viability. LÄS MER
23. Molecular analysis of factors regulating wood formation and seasonal growth cycles in hybrid aspen
Sammanfattning : Of all of the organisms on the planet, trees are perhaps the ultimate survivors. Their unique growth characteristics allow them to become both the largest and the oldest organisms on Earth. LÄS MER
24. Cellular mechanisms of plant regeneration
Sammanfattning : Plants are remarkable at healing. Humankind has long known about this and has exploited it by grafting different plants together for crop propagation and crop improvement. During graft formation, the surfaces of the cut tissues attach, the cells proliferate, and the vasculatures reconnect to form a chimeric plant. LÄS MER
25. Understanding the Molecular Basis of Differential Growth during Apical Hook Development
Sammanfattning : Plants’ adaptation to their environment often involves change in development, which in many cases involves the establishment of differential growth rates across organs, for instance during phototropic and gravitropic responses. A striking example of differential growth is the formation of the apical hook, a structure that forms to protect the apical meristem as seedlings penetrate through soil. LÄS MER
