Implication

Mathematical modeling study demonstrates steady-state equivalence between relative nutrient uptake and growth rate in plants, highlighting nutrient productivity as a key control parameter.

Key Points

Formulate a mathematical theory connecting plant nutrient uptake dynamics directly to relative growth rates under steady-state conditions.
Derived mathematical flux models relating relative nutrient uptake rate, relative growth rate, and internal nutrient concentration.
Controlled relative nutrient addition rates during exponential growth phases to experimentally observe steady-state growth and uptake stability.
Extended the formulation to post-exponential growth phases by incorporating biomass-dependent reductions in nutrient productivity caused by aging and self-shading.
Mathematical derivation showed that relative nutrient uptake rate precisely equals relative growth rate when internal nutrient concentrations remain constant.
Relative growth rate scaled linearly with internal nutrient concentration, where the slope defines nutrient productivity as a function of light and genome.
Experimental regulation of nutrient addition rates reproduced steady-state growth and stable internal nutrient concentrations with extremely low variability.
