Abstrakt: Arbuscular mycorrhizal (AM) symbiosis is heavily and positively implicated in phosphorus (P) acquisition from soil to plants, including many important agricultural crops. Its role in plant nitrogen (N) nutrition is generally not as prominent or beneficial, with exception of some situations when N is available predominantly in organic forms. Yet the AM fungi (AMF) are, due to their poor exo-enzymatic repertoire, unlikely to degrade organic compounds on their own, therefore they possibly depend on other microorganisms to liberate nutrients contained in those materials. Here, we review current knowledge on the roles played by the AMF in plant N nutrition in general and uptake of N from organic compounds in particular, with a specific reference to microbes and processes involved in liberation and AM fungal utilization of N from organic compounds. Future research needs and directions are outlined, as is the agronomic and societal context of such research.
