應用

Nitrogen-15N2 (15N Labeled nitrogen) can be used:
  • In nitrogen fixation experiments to monitor the resulting metabolites in an organism.
  • 15N2 pulse-chase experiments to understand the route of transport of fixed nitrogen from the nodule to the shoot in plants.
  • To quantify biological N2 production in agricultural soil.

Legumes obtain nitrogen from air through rhizobia residing in root nodules. Some species of rhizobia can colonize cereals but do not fix nitrogen on them. Disabling native regulation can turn on nitrogenase expression, even in the presence of nitrogenous fertilizer

Ammonium is a central nutrient in aquatic systems. Yet, cell-specific ammonium assimilation among diverse functional plankton is poorly documented in field communities. Combining stable-isotope incubations (15N-ammonium, 15N2 and 13C-bicarbonate) with secondary-ion mass spectrometry, we quantified bulk ammonium dynamics, N2-fixation and
