1. The Biodiversity of Hydrogenases in Frankia : Characterization, regulation and phylogeny
Abstract : All the eighteen Frankia strains isolated from ten different actinorhizal host plants showed uptake hydrogenase activity. The activity of this enzyme is further increased by addition of nickel. Nickel also enhanced the degree of hydrogenase transfer into the membranes of Frankia, indicating the role of this metal in the processing of this enzyme. READ MORE

2. 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

3. Endosymbiosis of Frankia cluster-2
Abstract : 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. READ MORE

4. 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
