1. Molecular mechanisms in actinorhizal symbioses
Sammanfattning : The symbiosis between the nitrogen fixing acinobacterium Frankia and its actinorhizal host plant is very old and their co-evolution has shaped their niche in the environment. Nitrogen is most often the limiting element in soil, and symbiotic plants can, with the help of their micrsymbionts, compete in an efficient way. LÄS MER
2. Jasmonates in root nodule development
Sammanfattning : Jasmonic acid (JA), its derivatives and its precursor form a group of phytohormones, the jasmonates, representing signal molecules involved in plant stress responses, in the defense against pathogens as well as in development. Elevated levels of JA have been shown to play a role in arbuscular mycorrhiza and in the induction of nitrogen-fixing root nodules. LÄS MER
3. Melanization and Hemocyte Homeostasis in the Freshwater Crayfish, Pacifastacus leniusculus
Sammanfattning : Blood cells or hemocytes play important roles in immunity. They are a major source of many immune-related molecules such as antibodies in adaptive immunity of vertebrates and prophenoloxidase (proPO) in invertebrates. LÄS MER
4. Borrelia channel-forming proteins : structure and function
Sammanfattning : Borrelia is a Gram-negative, corkscrew-shaped bacterium transmitted by infected ticks or lice. Borreliae are subdivided into pathogens of two diseases: Lyme disease, caused mainly by B. burgdorferi, B. afzelii and B. LÄS MER
5. The actinorhizal plant Datisca glomerata : interpreting its symbiotic adaptations by omics-based comparisons with model and non-model organisms
Sammanfattning : Nitrogen is the element that most often limits plant growth and development. Common agricultural practices rely on the application of large quantities of industrially-produced nitrogen fertilizer, which poses a worldwide environmental threat. Sustainable agriculture encourages the use of biologically fixed nitrogen. LÄS MER
