1. 1. Plant Nanobionics : From Localized Carbon Capture to Precision Molecular Delivery

   Författare :Cyril Routier; Eleni Stavrinidou; Magnus Berggren; Seon-Yeong Kwak; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant nanobionics; Nanoparticles; Chitosan-modified polyethyleneimine; Infiltration; CO2 capture; Photosynthesis;

   Sammanfattning : Photosynthesis is an evolutionary marvel that not only sustains plant life but also profoundly shaped the climatic conditions necessary for the development of other advanced forms of life and the ecosystems we know today. During photosynthesis, plants harness the energy of light to convert carbon dioxide (CO2), one of the main greenhouse gases, into sugars for the growth of both themselves and organisms that consume plants, and oxygen that sustains life on Earth.

3. 2. Verticillium longisporum and plant immunity responses in Arabidopsis

   Författare :Jonas Roos; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Verticillium spp. are soil-borne ascomycete fungi belonging to a subgroup of Sordariomycetes, and the three major plant pathogens Verticillium longisporum, V. dahliae and V. albo-atrum cause disease on numerous plant species worldwide. LÄS MER

4. 3. Life History Strategies in Linnaea borealis

   Författare :Mikael Niva; Brita M. Svensson; P. Staffan Karlsson; Ørjan Totland; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Linnaea borealis; apex removal; apical dominance; clonal plant; hand pollination; matrix modelling; plant foraging; resorption efficiency; resorption proficiency; resource heterogeneity; shoot dynamics; Biologi; Biology; Biologi; ekologisk botanik; Ecological Botany;

   Sammanfattning : About 70% of the plant species in the temperate zone are characterised by clonal growth, clonal species are also in majority in the Arctic and Subarctic where they affect the structure and composition of the vegetation. It is therefore of great importance to increase our knowledge about clonal plants and their growth and life histories. LÄS MER

5. 4. The role of regeneration in plant niche differentiation and habitat specialization

   Författare :Dirk-Jan ten Brink; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; seed mass; seed size; drought; shade; seed germination; seed dormancy; seedling establishment; plant community ecology; assembly rules; habitat specialization; plant recruitment; Regeneration; niche differentiation; phylogenetic independent contrasts; plant traits; soil fertility; comparative ecology;

   Sammanfattning : To predict the effects of environmental change and nature management on the distribution of plant species, it is crucial to understand the mechanisms of plant niche differentiation and habitat specialization. The importance to habitat specialization of particular plant traits and requirement of the regenerative phase of the plants life has received scanty interest. LÄS MER

7. 5. Genetic structure and dispersal in plant populations

   Författare :Johan Fogelqvist; Martin Lascoux; Sophie Gerber; Beng-Olle Bengtsson; Uppsala universitet; []
   Nyckelord :population genetics; dispersal; structure; plant; gene flow;

   Sammanfattning : This thesis focuses on the spatial structure and methods to identify spatial structure in plants. Methods that investigate genetic structure can mainly be divided into equilibrium methods that reveal summed dispersal over many generations, and cluster methods, that reveal more recent dispersal events.
