Short summary
Plant nitrogen (N) isotope composition is an indicator of N cycling. How N isotopes are distributed within plants is not well understood. We found intra-plant variations in N isotopes were related to organ N and phosphorous (P) contents and predicted by the N–P interaction. We hypothesized that plant N volatilization, resorption and remobilization of N and P from senescing leaves, and mixing of the re-translocated foliar N and P, are responsible for the observed intra-plant N isotope variations.
