2. 1. Secondary Metabolites from Mozambican Plants

   Author : Julião Monjane; Centrum för analys och syntes; []
   Keywords : Secondary metabolites; Mozambique; Medicinal plants; Isolation; Structural elucidation; Antileishmanial activity;

   Abstract : Products derived from different natural sources have been used for thousands of years by human beings for their everyday needs. Out of these natural sources, plants were the most affordable. Plant-derived products were used for shelter, food, and as medicines. READ MORE

4. 2. Antioxidant Activity of Bolivian Plant Secondary Metabolites

   Author : Patricia Mollinedo; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cytoprotection; Beta-carotene; TBARS; TEAC; ABTS; antioxidant activity; secondarymetabolites; Highland plains; plants; photoprotection; Organic chemistry; Organisk kemi;

   Abstract : Certain climatologically-adverse conditions in the basin of the Poopo Lake, located on the high plateau of the Bolivian Altiplano, have prevented the existence of a reliable agricultural system and the impact on the population of the area has been severe. These problems have been the main motivation in choosing this region for this particular study. READ MORE

5. 3. Elicitor-induced formation of secondary products in plant cell cultures. Production of benzophenanthridine alkaloids in Eschscholtzia californica Cham. and hydroxycinnamic acid tyramides in Nicotiana glutinosa L

   Author : Mirza Villegas; Biokemi och Strukturbiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; macarpine; chelerythrine; sanguinarine; benzophenanthridine alkaloids; Nicotiana glutinosa; Eschscholtzia californica; secondary metabolites; Key words elicitors; immobilisation; hydroxycinnamoyltyramides.; Plant biochemistry; Växtbiokemi;

   Abstract : Biotic and abiotic elicitors induce biosynthesis of secondary metabolites (phytoalexins) as a defense against pathogenic organisms in plants. The use of cell suspension cultures in combination with elicitors offer excellent experimental model systems for studies on various elicitor-induced responses of plant tissues. READ MORE

6. 4. Integration of Arabidopsis and poplar model systems to elucidate gene function during wood formation

   Author : Ellinor Edvardsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Wood is an essential raw material being used for a number of different applications including construction, pulp and paper production and as a source of biomass for bioenergy generation. The increasing number of sequenced plant genomes provides powerful tools to evaluate plant gene function. READ MORE

7. 5. Spatial patterns in the interaction between Salix triandra and associated parasites

   Author : Lena Niemi; Anders Wennström; Lars Ericson; Keith Clay; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gonioctena linnaeana; host-parasite interactions; leaf beetle; local adaptation; Melampsora amygdalinae; phenolics; pathogens; plant host; secondary chemistry; Terrestrial ecology; Terrestisk ekologi;

   Abstract : This thesis focuses on mechanisms and processes underlying spatial patterns of resistance and virulence and on local adaptations in plant–parasite interactions. The model system used comprises the plant host Salix triandra, the pathogenic rust fungus Melampsora amygdalinae, the leaf beetle Gonioctena linnaeana, and the galler Pontania triandrae. READ MORE
