1. 1. Context dependency of plant – animal interactions

   Författare :Malin A. E. König; Johan Ehrlén; Christer Wiklund; John Stinchcombe; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Anthocharis cardamines; attack intensity; Cardamine pratensis; cytotype; herbivory; larval fitness; oviposition; phenology; plant-animal interactions; plant resistance; plant tolerance; polyploidy; spatial variation; trait variation; Plant Ecology; växtekologi;

   Sammanfattning : The strength and direction of interactions between organisms vary spatially across the landscape. Traditionally, the focus has been on how trait variation affects the interactions between species. However, differences in abiotic and biotic environmental factors may also alter the distribution, phenology and behavior of the interacting species. LÄS MER

3. 2. 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.

4. 3. Ecology and evolution of tolerance in two cruciferous species

   Författare :Elin Boalt; Kari Lehtilä; Johan Ehrlén; Julia Koricheva; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; herbivory; tolerance; methodology; Raphanus raphanistrum; Cardamine pratensis; folivory; apex removal; plant competition; ploidy levels; herbivore pressure; Other biology; Övrig biologi; växtekologi; Plant Ecology;

   Sammanfattning : Tolerance to herbivory is the ability of plants to maintain fitness in spite of damage. The goal of this thesis is to investigate the genetic variation and expression of tolerance within species, determine whether and in what conditions tolerance has negative side-effects, and how tolerance is affected by different ecological factors.

5. 4. The circadian clock in annuals and perennials : coordination of Growth with Environmental Rhythms

   Författare :Mikael Johansson; Maria E. Eriksson; Paul Devlin; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; circadian clock; arabidopsis; populus; Molecular biology; Molekylärbiologi; Plant biotechnology; Växtbioteknik; Plant physiology; Växtfysiologi; molekylärbiologi; Molecular Biology;

   Sammanfattning : Since the first signs of life on planet earth, organisms have had to adapt to the daily changes between light and dark, and high and low temperatures. This has led to the evolution of an endogenous time keeper, known as the circadian clock. LÄS MER

7. 5. Studies on plant-microbe interaction to improve stress tolerance in plants for sustainable agriculture

   Författare :Shashidar Asari; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Biotic and abiotic stress factors have a major impact on plants and cause extensive losses to crop production. Bacteria that provide growth promotion and prime stress tolerance of plants have great potential to improve crop production and support durable and environmental friendly resource management. LÄS MER
