In this paper, we present CN-Wheat, a comprehensive and mechanistic model of carbon (C) and nitrogen (N) metabolism within wheat culms after anthesis. Methods The culm is described by modules that represent the roots, photosynthetic organs and grains. Each of them includes structural, storage and mobile materials. Fluxes of C and N among modules occur through a common pool and through transpiration flow. Metabolite variations are represented by differential equations that depend on the physiological processes occurring in each module. A challenging aspect of CN-Wheat lies in the regulation of these processes by metabolite concentrations and the environment perceived by Annals of botany997-1013https://www.ebi.ac.uk/biostudies/studies/S-EPMC5055822biostudies-literatureCN-Wheat, a functional-structural model of carbon and nitrogen metabolism in wheat culms after anthesis.
