1. The actinorhizal plant Datisca glomerata : interpreting its symbiotic adaptations by omics-based comparisons with model and non-model organisms
Abstract : 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. READ MORE

2. The actinorhizal symbiosis of Datisca glomerata: Search for nodule-specific marker genes
Abstract : 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. READ MORE

3. The actinorhizal symbiosis of the earliest divergent Frankia cluster
Abstract : In recent years, the need to reduce reliance on synthetic nitrogen fertilizer has led to extensive research on biological nitrogen fixation, especially on root nodule symbioses. My study focuses on actinorhizal symbioses, the symbiotic interactions between members of nitrogen-fixing soil actinobacteria from the genus Frankia and a diverse group of plants from eight families, collectively called actinorhizal plants.

4. To be together or not to be together : Ca. 100 million years of evolutionary history of the earliest divergent Frankia clade
Abstract : Root nodule symbiosis evolved ca. 100 Mya between a nitrogen-fixing bacterium and the common ancestor to the Fabales, Fagales, Rosales, and Cucurbitales plant orders. Over time the majority of the lineages derived from this ancestor lost their symbiotic capability. READ MORE

5. Molecular mechanisms in actinorhizal symbioses
Abstract : 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. READ MORE
