Larbat2016.3 - Modeling the diversion of primary carbon flux into secondary metabolism under variable nitrate and light or dark conditions (Light Dark Cycles with Minimum Starch Adaption)

ABSTRACT: This is a global mathematical model describing metabolic partitioning of carbon resources in plants between growth and defense, as a function of nitrate fertilization. The model hinges on the dynamics of sucrose inflow/outflow properties. The model also accounts for variations in photosynthetic activity as dictated by a daily light/dark cycle. Furthermore, the adaptive changes in starch metabolism that occur with changing light durations (short days vs long days) are also investigated.

In plants, the partitioning of carbon resources between growth and defense is detrimental for their development. From a metabolic viewpoint, growth is mainly related to primary metabolism including protein, amino acid and lipid synthesis, whereas defense is based notably on the biosynthesis of a myriad of secondary metabolites. Environmental factors, such as nitrate fertilization, impact the partitioning of carbon resources between growth and defense. Indeed, experimental data showed that a shor  ...[more]
