Accurate analysis of N fixation in leguminous crops requires determination of N utilization within an intact plant$$;$$ however, most approaches require tissue disassembly. We developed a simple and rapid technique to generate high-purity and high-yield [$$^{13}$$N]N$$_2$$ gas and obtained real-time images of N fixation in an intact soybean plant. The purification efficiency was $$sim$$ 81.6% after decay correction.

The impacts of oxygen in rhizosphere on the symbiotic nitrogen fixation in real-time was evaluated under various O$$_{2}$$ partial pressure. Soybean nodules were treated with mixed gas containing N$$_{2}$$ labeled with a radioisotope $$^{13}$$N and various concentrations of O$$_{2}$$, and the nitrogen fixation activity in the nodules was visualized by the positron-emitting tracer imaging system (PETIS). The results showed that under normal condition the nitrogen fixation ability of soybean plant was higher compared to that of under the other conditions (0% O$$_{2}$$ and 10% O$$_{2}$$). There was no significant difference in the nitrogen fixation activity between 0% O$$_{2}$$ and 10% O$$_{2}$$.
