What are Frankia root nodules? Frankia root nodules are specialized nitrogen-fixing structures that form on the roots of woody angiosperms following colonization by soil bacteria of the genus Frankia (Figure 1). Within these nodules, Frankia converts atmospheric dinitrogen (N2) into ammonia — a form of nitrogen the plant can assimilate — in exchange for photosynthetically derived carbon. The result is a mutualism with considerable ecological consequence: actinorhizal symbioses contribute fixed nitrogen to soils at rates comparable to the well-studied legume–rhizobia system, yet they occur in ecosystems ranging from boreal forests, riparian systems to coastal dunes, where legumes are largely absent.
