ProNet-CN model: A dynamic and multi-scale process network combining photosynthesis, primary carbon metabolism and effects of leaf nitrogen status

摘要

Integrating the hierarchical organization of metabolic and physiological plant processes into crop models is a task that is not solved satisfactorily up to now. To this aim here we present a new multi-scale crop systems biology model. This integrative whole plant modeling framework is based on a complex, hierarchically structured modular process model network considering carbon metabolism and leaf nitrogen status: the ProNet-CN model. ProNet-CN combines the nitrogen sensitive photosynthesis and transpiration model LEAFC3-N with modules describing the dynamics of mass balances of main functional carbon compounds and its allocation between interacting source and sink organs. On this basis, biomass formation of the individual plant organs and of the whole plant is calculated.
