Root system architecture is a major determinant of plant fitness. The ability to precisely control root system architecture would enable farmers to optimize plant fitness for field conditions, maximizing production efficiency. Dicot plants have tap root systems comprising of a tap root that extends downwards throughout a plant’s life from which lateral roots emerge. I aim to interrogate mechanisms underlying cellular decision making during lateral root development using an agent-based model. I will use this model to identify control inputs and perturbations that allow for the precise control of lateral root formation.
