1. 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
2. The actinorhizal symbiosis of Datisca glomerata: Search for nodule-specific marker genes
Sammanfattning : The actinorhizal symbiosis is entered by nitrogen-fixing actinobacteria of the genus Frankia and a large group of woody plant species distributed among eight dicot families. The actinorhizal symbiosis, as well as the legume-rhizobia symbiosis, involves the stable intracellular accommodation of the microsymbionts in special organs called root nodules. LÄS MER
3. 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
4. Endosymbiosis of Frankia cluster-2
Sammanfattning : Actinobacteria of the genus Frankia engage in root endosymbiosis with actinorhizal plants belonging to the Fagales, Cucurbitales and Rosales. The genus Frankia consists of four different clades. Strains belonging to cluster-1, -2, and -3 exhibit host-specificity which plants they can nodulate, while cluster-4 strains do not engage in symbiosis. LÄS MER
5. Conservation of transcription factors in infected cells of nitrogen-fixing root nodules
Sammanfattning : Infected cells of nitrogen-fixing root nodules are the only plant cells that can stably internally accommodate a eubacterial symbiont. In the context of studying the differentiation of infected cells, we set about to analyse the conservation of infected cell-specific transcription factors using altogether four different promoters from genes showing infected cell-specific expression, or nodule-specific expression.
