Root Nodule Symbiosis: Nodulins and Nodulin Genes

Part of the Plant Gene Research book series (GENE)


The soils in which plants grow are heavily populated with a variety of microorganisms, and a wide range of plant-microbe interactions have evolved, driven in the main by the microbes’ requirements for organic nutrients. Many of these interactions involve potent pathogens that are detrimental to the plant; however, some microorganisms such as diazotrophic bacteria and mycorrhizal fungi enter into beneficial, symbiotic associations with plants.
