WebNitrogen fixation (the conversion of inert nitrogen to ammonium, ammonia, nitrate, or nitrogen oxides) is a process which occurs naturally, but can also occur through anthropogenic processes. Natural nitrogen fixation is performed by a number of microorganisms, called diazothrops. In 1969, Schwartz at Indiana University was able to artificially induce gene fixation into maize, by subjecting samples to suboptimal conditions. Schwartz located a mutation in a gene called Adh1, which when homozygous causes maize to be unable to produce alcohol dehydrogenase. Schwartz then subjected seeds, with both normal alcohol dehydrogenase activity and no activity, to flooding conditions and observed whether the seeds were able to germinate or not.
