Nitrogen fixation and lightning
Did you know?
WebbThis process is called nitrogen fixation. A very small amount of nitrogen is fixed via lightning interacting with the air. Once nitrogen is fixed, other types of bacteria convert ammonia to nitrate (NO 3 ‑) and nitrite (NO 2 –), which can then be used by other bacteria and plants. Consumers (herbivores and predators) get nitrogen compounds ... WebbIn the present work, the formation of nitrogen oxides by laboratory scale discharges has been examined, to try to help clarify the mechanism of formation by lightning, which is not as amenable to study. The velocity of the shock front generated by laboratory scale discharges has been examined experimentally.

WebbPlant–rhizobia symbiosis can activate key genes involved in regulating nodulation associated with biological nitrogen fixation (BNF). Although the general molecular basis of the BNF process is frequently studied, little is known about its intraspecific variability and the characteristics of its allelic variants.
