An attempt to model the induction and the feedback inhibition of nitrate uptake in wheat seedlings

The aim of the present study was to develop a mathematical model in attempt to describe the induction and feedback inhibition phases of nitrate uptake in wheat (Triticum durum L. cv. Appulo) seedlings. The model proposed is based on three autonomous, non-linear, and time-dependent differential equations showing good agreement with our experimental data. The model could be fruitfully applied for a correct evaluation of different patterns of nitrate uptake owing to genetic and physiometabolic plant characteristics and external nutrient availability
