Abstract

Recent studies indicate that a multitude of microbial processes are involved in nitric oxide production and consumptions in the pedosphere. Due to its dual function as a toxic metabolite and signaling compound, we speculate that this pedospheric nitric oxide of microbial origin can significantly interact with mycorrhizal symbioses and symbiotic nitrogen fixation of legumes.

Keywords: nitric oxide; pedospheric NO production; root mycorrhizal symbioses; root symbiotic N fixation interaction.
