δ15N values in plants are determined by both nitrate assimilation and circulation
J Cui, E Lamade, F Fourel, G Tcherkez - New Phytologist, 2020 - Wiley Online Library
Nitrogen (N) assimilation is associated with 14N/15N fractionation such that plant tissues are
generally 15N‐depleted compared to source nitrate. In addition to nitrate concentration, the …
