2. 1. Analysis of plant growth regulating substances

   Author : Barbro Andersson; Bo Jansson; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant regulators; phytohormones; pine; spruce; anther; abscisic acid; 3-indoleacetic acid; gibberellin Ag; N- 3-indoleacetyl -aspartic acid; dichlorophene; Amberlite XAD-7; identification; quantification; GC; HPLC; GC-MS; GC-MID; Hormoner;

   Abstract : Natural plant growth regulators (phytohormones) are a group of organic compounds which, in very small amounts, act as regulators of physiological processes in plants.Methods were developed for the analysis of phytohormones in samples from Norway spruce (Picea abies (L.) Karst.) and Scots pine (Pinus sylvestris (L. READ MORE

4. 2. Molecular analysis of factors regulating wood formation and seasonal growth cycles in hybrid aspen

   Author : Anna Karlberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : 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. READ MORE

5. 3. Dissecting the gene regulatory networks behind carbon allocation in plants : ex situ studies on combinatorial and subdomains effects of seed transcription factors

   Author : Per Snell; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Plants store excess energy and metabolites derived from photosynthesis in a variety of storage compounds with starch, protein and triacyglycerol (oil, TAG) being the most common. As humans, we are completely dependent on these compounds either directly as food or indirectly, as materials for large number of goods or feed for animals. READ MORE

6. 4. Molecular regulation of vascular cambium identity and activity

   Author : Melis Kucukoglu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : In plants, secondary development and wood formation originates from the cell divisions within the vascular meristem, where the vascular stem cells are located. This thesis work presents my results on the molecular regulation of vascular cambium stem cell identity and activity. READ MORE

7. 5. MADS-Box Gene Phylogeny and the Evolution of Plant Form : Characterisation of a Family of Regulators of Reproductive Development from the Conifer Norway Spruce, Picea abies

   Author : Annelie Carlsbecker; Quentin Cronk; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Växtfysiologi; Plant physiology; Växtfysiologi; Fysiologisk botanik; Physiological Botany;

   Abstract : The evolutionary relationships between the angiosperm floral organs and the reproductive organs of other seed plants is not known. Flower organ development requires transcription factors encoded by the MADS-box genes. READ MORE
