2. 1. Ecology and Evolution of Resistance to Herbivory : Trichome Production in Arabidopsis lyrata

   Author : Geir Løe; Jon Ågren; Kari Lehtilä; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Plant-animal interactions; herbivory; trichomes; plant resistance; plant defense; divergent selection; local adaptation; GLABROUS1; evolution; matrix population models; LTRE; Biologi; Biology; Biologi;

   Abstract : In this thesis, I examine variation in occurrence and performance of glabrous and trichome-producing plants of the perennial herb Arabidopsis lyrata. I combine field studies and genetic analysis to (1) examine the function of trichomes as a resistance character in natural populations, (2) compare the magnitude of population differentiation in trichome-production and at putatively neutral marker loci, (3) examine the molecular genetic basis of trichome-production, and (4) quantify the effects of herbivore removal on population growth and relative performance of glabrous and trichome-producing plants.

5. 3. Characterization of New Players in Planar Polarity Establishment in Arabidopsis

   Author : Stefano Pietra; Markus Grebe; Niko Geldner; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SABRE; planar polarity; CLASP; cell division orientation; microtubule cytoskeleton; actin; AIP1; patterning; Developmental Biology; miljömedicinsk utvecklingsbiologi;

   Abstract : Coordinated polarity and differentiation of cells in the plane of a tissue layer are essential to the development of multicellular organisms. Arabidopsis thaliana root hairs and trichomes provide model systems to study the pathways that control planar polarity and cell fate specification in plants. READ MORE

6. 4. Evaluation of plant resistance in field pea by host plant choice behaviour of pea weevil (Bruchus pisorum L.) : implications for pest management

   Author : Esayas Mendesil; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Field pea (Pisum sativum L.) is an important grain legume crop due to its nutritional value and role in improving soil fertility in cropping systems. Insect pests are one of the main production constraints for field pea, with pea weevil (PW), (Bruchus pisorum L.) being an economically important pest of field pea worldwide. READ MORE

7. 5. Revisiting push-pull technology: Below and aboveground mechanisms for ecosystem services

   Author : Aneth Bella David; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Push-pull technology is an effective and ecological solution to suppressing major Lepidopteran pests of cereals, in particular stem-borers (Busseola fusca, Chilo partellus), the fall armyworm (Spodoptera frugiperda) and the parasitic weed Striga. The technology exploits plant-insect interactions in intercropping practices to manage the pests, increasing productivity while maintaining ecosystem resilience. READ MORE
