1. 1. Epigenetic Regulation of Light and Hormonal Signaling in Arabidopsis thaliana

   Författare :Kristina Rizzardi; Annika Sundås-Larsson; Katarina Landberg; Johan Memelink; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TERMINAL FLOWER2; auxin; jasmonate; epigenetics; photomorphogenesis; Plant physiology; Växtfysiologi; Biologi med inriktning mot fysiologisk botanik; Biology with specialization in Physiological Botany;

   Sammanfattning : Plants are stationary and need to adapt to the environment they live in. Integration of environmental cues, such as changes in light and temperature, can occur either directly or through the action of hormones. Hormone and light signaling leads to rapid changes in gene expression, and eventually changes in protein levels. LÄS MER

3. 2. Light, stress and herbivory : from photoprotection to trophic interactions using Arabidopsis thaliana as a model organism

   Författare :Martin Frenkel; Jon Moen; Stefan Jansson; Don Cipollini; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; photoprotection; herbivory; light-stress; jasmonate; fitness; FDE; dual-choice; Biology; Biologi;

   Sammanfattning : Photosynthesis is the most important process for nearly all life on earth. Photosynthetic organisms capture and transfer light energy from the sun into chemical energy which in turn provides a resource base for heterotrophic organisms. Natural light regimes are irregular and vary over magnitudes. LÄS MER

4. 3. A molecular network mediating adventitious root initiation in Arabidopsis thaliana

   Författare :Abdellah Lakehal; Catherine Bellini; Malcolm Bennett; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Adventitious rooting; auxin; jasmonate; cytokinin; phytohormone perception and signalling; vegetative propagation;

   Sammanfattning : To adapt to the ever-changing rhizosphere conditions, land plants evolved a sophisticated root system. The genetic determinants of the root system establishment have been the targets of natural selection, resulting in a very complex but robust molecular networks and circuits. LÄS MER

5. 4. Characterization of adventitious root formation in Populus species and Norway spruce

   Författare :Sanaria Alallaq; Catherine Bellini; Carmen Diaz-Sala; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Adventitious root; Conifers; Picea abies; auxin; cytokinins; jasmonate; red light; Populus spp.; hybrid poplar; hybrid aspen; cambium; stem cuttings; P. tremula; Swedish Aspen SwAsp collection;

   Sammanfattning : Adventitious root (AR) formation is a form of post-embryonic development and is a key adaptive trait in plants. De novo adventitious root regeneration represents an elegant evolutionary innovation that allows many plant species to multiply through vegetative propagation; it is widely used in forestry and horticulture to multiply elite genotypes.

   Sammanfattning : The chemical elicitor methyl jasmonate (MeJA) could replace insecticides in Europe and Asia for protection of young conifers against the pine weevil (Hylobius abietis). This thesis mainly focuses on the effects of MeJA treatment on chemical defenses of conifers from seedling batches with documented field resistance. LÄS MER
