The strategic role of 15N in quantifying the contribution of endophytic N2 fixation to the N nutrition of non-legumes

Methods based on the use of the stable isotope 15N have been used to confirm active endophytic biological N2 fixation (BNF) in non-legumes, to obtain quantitative estimates of the proportion of plant N obtained from the atmosphere (P atm), and to assess the response of plants to inoculation with diazotrophic bacteria. The purpose of this review is to… CONTINUE READING
