	Frankia is a type of actinomycete that forms a symbiotic relationship with [[plant roots]] in order to form actinorhiza for nitrogen fixation. To form these symbiotic relationships, the Frankia strain sends out hyphae, which burrow into the roots and reside in between the cell wall structures of the plant cells. [4] These hyphae will typically enter into the roots through the fine hairs coming off of the roots, but in certain situations, the hyphae can go directly into the cells themselves. Once the strain of Frankia enters the root hair, it will begin to make the root hair have deformities. These deformities include curling of the root hair and certain types of branching patterns. It is believed that these deformities allow easier passage of enzymes between the Frankia and the cell walls because the deformities disorganize the cell walls to make them more loosely packed together. This ease of access to the enzymes then allows the Frankia to dive even deeper into the interior of the root hair. From there, the Frankia strain will facilitate the growth of actinorhiza nodules from within the [[root hairs]]. [5] However, certain strains of Frankia can only grow in certain habitats. Different strains have been found to grow within different elevations, but there were some strains that were found at multiple elevations. It has been determined that the majority of Frankia strains are found at intermediate elevations, but also with intermediate precipitation, while the lowest number of Frankia strains were found at low elevations, but with high precipitation, and high elevations with low precipitation. Not only that, but Frankia strains have been observed to appear with more genetic [[diversity]] in soils that contain higher amounts of vegetation cover due to the enhanced [[soil]] fertility and the improved soil physical and chemical [[properties]] by root penetration and soil aggregation. It is also assumed that Frankia concentration is affected by other factors such as temperature, soil type, soil moisture, pH, and organic matter content. [7] Since these factors affect the growth of Frankia, it can also be said that these factors influence the growth of actinorhiza as well.

	These nodules are essential to plant growth, as plants struggle to find sources of nitrogen without them, making it difficult for them to grow and stay alive. However, root nodules are not able to form on every kind of plant. The type of plant that can host the nodules consist mainly of legumes. Other types of plants must rely on other sources of nitrogen, which for crops and other plants grown by farmers, comes from fertilizer. A study done by Horst Rohrig and Richard Walden shows that nodules can be artificially grown on non-leguminous plants. The use of lipo-chitooligosaccharides, or LCOs, shows that non-leguminous plants can undergo the same type of cell division to create nodules on their roots. Although these nodules do not have the same nitrogen fixation ability as the naturally occurring nodules, this study does show that LCOs are a main factor of plant and root nodule growth.

	Leguminous plants can obtain root nodules through either legume-rhizobium symbiosis or actinorhiza, which both require a certain symbiosis receptor-kinase gene known as SYMRK in order to perform symbiosis with the plant. These types of root nodules differ based on their bacterial partner, intracellular infection pattern, and morphogenesis. The bacteria that ~~makes~~ up the actinorhiza will always stay within the infection threads, which are tubular structures that are surrounded by a host-derived membrane that is continuous with the plasma membrane, and bound by plant cell wall-like material, during the nitrogen fixation process. Meanwhile, legume-rhizobium bacteria can either remain in the infection threads or leave in order to develop into bacteroids.

From there, the Frankia strain will facilitate the growth of actinorhiza nodules from within the root hairs. [5] However, certain strains of Frankia can only grow in certain habitats. Different strains have been found to grow within different elevations, but there were some strains that were found at multiple elevations. It has been determined that the majority of Frankia strains are found at intermediate elevations, but also with intermediate precipitation, while the lowest number of Frankia strains were found at low elevations, but with high precipitation, and high elevations with low precipitation. Not only that, but Frankia strains have been observed to appear with more genetic diversity in soils that contain higher amounts of vegetation cover due to the enhanced soil fertility and the improved soil physical and chemical properties by root penetration and soil aggregation. It is also assumed that Frankia concentration is affected by other factors such as temperature, soil type, soil moisture, pH, and organic matter content. [7] Since these factors affect the growth of Frankia, it can also be said that these factors also influence the growth of actinorhiza.		Frankia is a type of actinomycete that forms a symbiotic relationship with plant roots in order to form actinorhiza for nitrogen fixation. To form these symbiotic relationships, the Frankia strain sends out hyphae, which burrow into the roots and reside in between the cell wall structures of the plant cells. [4] These hyphae will typically enter into the roots through the fine hairs coming off of the roots, but in certain situations, the hyphae can go directly into the cells themselves. Once the strain of Frankia enters the root hair, it will begin to make the root hair have deformities. These deformities include curling of the root hair, and certain types of branching patterns. It is believed that these deformities allow easier passage of enzymes between the Frankia and the cell walls because the deformities disorganize the cell walls to make them more loosely packed together. This ease of access of the enzymes then allows the Frankia to dive even deeper into the interior of the root hair. From there, the Frankia strain will facilitate the growth of actinorhiza nodules from within the root hairs. [5] However, certain strains of Frankia can only grow in certain habitats.
