11. Molecular properties of disordered plant dehydrins : Membrane interaction and function in stress
Sammanfattning : Dehydrins are intrinsically disordered plant stress-proteins. Repetitively in their sequence are some highly conserved stretches of 7-17 residues, the so called K-, S-, Y- and lysine rich segments. LÄS MER
12. Thriving in extremes : Local adaptation of grasses (Poaceae) to geothermally heated soils on a subarctic island
Sammanfattning : Temperature is one of the most decisive parameters when it comes to determining characteristics and distributions of life worldwide. For plants, as sessile organisms, it is particularly important to be able to deal with the temperatures they are exposed to at a given location. LÄS MER
13. Abiotic and biotic methane dynamics in relation to the origin of life
Sammanfattning : Methane (CH4) plays an important role in regulating Earth’s climate. Its atmospheric concentrations are related to both biotic and abiotic processes. The biotic one can be formed either by chemoautotrophic or heterotrophic pathways by methanogens. LÄS MER
14. Biotic and abiotic drivers of life-history and demographic variation in boreal orchids
Sammanfattning : Environmental interactions, including both abiotic and biotic factors, are key drivers of life-history and population dynamics. Despite this, most population studies do not explicitly link variation in environmental factors and vital rates. LÄS MER
15. Roles of LESIONS SIMULATING DISEASE1 and Salicylic Acid in Acclimation of Plants to Environmental Cues : Redox Homeostasis and physiological processes underlying plants responses to biotic and abiotic challenges
Sammanfattning : In the natural environment plants are confronted to a multitude of biotic and abiotic stress factors that must be perceived, transduced, integrated and signaled in order to achieve a successful acclimation that will secure survival and reproduction. Plants have to deal with excess excitation energy (EEE) when the amount of absorbed light energy is exceeding that needed for photosynthetic CO2 assimilation. LÄS MER
