	Frankia - MicrobeWiki
		Frankia is a nitrogen-fixing bacterium that lives in the soil and has a symbiotic relationship with many plants.
		Frankia (both Frankia that lives in a symbiotic relationship with plants and free-living Frankia strains) secrete extracellular proteins that might be involved in processes like bacteriolysis, hydrolysis, and virulence.
		Frankia alni's specific role in these relationships is to infect the roots of plants: it deforms root hairs of its plant host by going into the cortical cells and causing the formation of nodules.

	Frankia alni ACN14a
		The Frankia alni ACN14a strain was isolated from a green alder (Alnus crispa) growing in Tadoussac, Canada.
		Frankia alni causes root hair deformation: it penetrates the cortical cells and induces the formation of nodules which resemble those induced by Rhizobium in legumes.
		The Frankia sequencing project, which takes the form of a collaborative project between Genoscope, the CNRS and the University of Lyon (Center for Microbial Ecology, UMR CNRS 5557), with help from numerous other teams, began in October 2003.

		Frankia is a filamentous, branching, Gram-positive actinomycete, whereas Rhizobia are Gram-negative unicellular bacteria.
		Legume root nodules represent stemlike structures with peripheral vascular bundles and infected cells in the central tissue, whereas actinorhizal nodules conserve the structure of a lateral root with a central vascular bundle and peripheral infected cortical tissue (Pawlowski and Bisseling, 1996; Bogusz et al., 1996).
		Frankia penetrates the curled root hairs and infection proceeds intracellularly in the root cortex.

		The abundance of compatible Frankia strains in some areas was indicated by profuse nodulation of the host plants, whereas soil samples from other localities failed to result in nodulation.
		Genetic diversity among Frankia strains nodulating D. cannabina was determined by sequence analysis of the partial 16S rRNA gene amplified from nodules induced by soil samples from different localities by PCR.
		Sequence comparison based on 930 nucleotides indicated that the endophyte of D. cannabina nodules belongs to the genus Frankia and is highly related to the endophyte of C. nepalensis root nodules.

		The long term objective of my research program is to understand the physiology and ecology of nitrogen fixation in actinorhizal plants.
		Frankia differs from rhizobia in that it can fix nitrogen at atmospheric conditions when grown in pure culture and thus is able to provide its own oxygen regulation.
		This hemoglobin has kinetic constants for oxygen binding that are consistent with the facilitation of oxygen diffusion over short distances such as those within Frankia cells.

		Oxygen exclusion in Frankia spp., members of an actinomycetal genus that forms nitrogen-fixing root-nodule symbioses in a wide range of woody Angiosperms, is accomplished within specialized structures termed vesicles, where nitrogen fixation is localized.
		The Frankia vesicle envelope thus represents a layer specific to the locus of nitrogen fixation that is biosynthetically uniquely derived.

		Scientists at the Department of Forestry are conducting biotechnology research to better understand some of the diverse organisms that occupy forests, as well as to enhance methods for genetically manipulating these organisms.
		Recent technological advances allow "fingerprinting" of Frankia strains based on the nucleotide sequence of RNA contained in ribosomes or cellular organelles that facilitate protein synthesis.
		We have found that ribosomal RNA varies considerably among Frankia strains, so we can now characterize Frankia collected from different nodules on the same plant, from plants growing in different areas, or even from different soil samples.
