Detailed metabolite concentrations for C (left panels) and N (right panels) for two examples of photosynthetic organs

Simulating carbon and nitrogen patterns using an integrated model of wheat functioning

Based on a mechanistic approach, the CN-Wheat model simulates the fluxes of carbon (C) and nitrogen (N) metabolites in wheat plants after anthesis. Barillot et al. show that the CN-Wheat model can be used to predict allocation and dynamics of C and N resources among culm organs in conjunction with observations from field experiments.

Detailed metabolite concentrations for C (left panels) and N (right panels) for two examples of photosynthetic organs: lamina n (A, B) and the enclosed (enc) part of the peduncle (C, D). Simulations are shown during the organโ€™s lifespan. The vertical dashed line represents the beginning of the rapid filling stage of grains.

CN-Wheat also provides insights into how depletion of mobile metabolites caused by grain filling ultimately results in the cessation of resource capture. CN-Wheat appears to be an appropriate model with which to investigate and reveal the myriad functions of integrated plant behaviour.
