16. Insights into the Molecular Mechanisms of Litter Decomposition and Assimilation of Nitrogen by Ectomycorrhizal Fungi
Sammanfattning : Ectomycorrhizae is the dominant type of mycorrhiza found in association with tree roots in boreal and northern temperate forests. In this symbiosis, the fungal partner derives energy from photosynthates provided by the host trees and in return delivers soil-derived nutrients such as nitrogen (N). LÄS MER
17. Circumpolar impacts of herbivores on Arctic tundra vegetation
Sammanfattning : Arctic tundra vegetation provides many ecological services that have implications for the global climate. However, the tundra biome is currently changing in response to increasing temperatures. Herbivores may mitigate some of these responses to warming through their impact on Arctic vegetation. LÄS MER
18. Studies of different secondary metabolites : Natural products from the mevalonate pathway
Sammanfattning : Natural products, also called secondary metabolites, are small molecules that are not involved in main life processes. These can be produced by any living organism and play important roles as chemical weapons, protecting the organism from the competitive environment. LÄS MER
19. Role of mycorrhiza symbiosis and phosphorus nutrition in plant growth, photosynthesis and secondary metabolism
Sammanfattning : Inorganic phosphorus (Pi) is an important and often limiting nutrient for plants. Large amounts of Pi fertilizers derived from non-renewable rock phosphorus, are used in agriculture. These are applied in excess but crops take up only a small amount of Pi; the residual Pi ends up in water systems where it causes problems with eutrophication. LÄS MER
20. Terpenoid Plant Metabolites - Structural Characterization and Biological Importance
Sammanfattning : In response to the challenges of their local environments, organisms produce of a large number of chemical diverse compounds with complex stereochemistry and reactive functional groups. These characteristics enable them to interact and bind specifically to biological target molecules and exert various biological activities, and have assured that Natural products continues to be an important source of bioactive compounds, which, for example, facilitate the search for new lead structures that can be developed into new pharmaceuticals.
