Mathematical model of auxin distribution in the plant root

Mathematical model of auxin distribution in the plant root Auxin regulation of plant growth and development is mediated by controlled distribution of this hormone and dose-dependent mechanisms of its action. A mathematical model is proposed, which describes auxin distribution in the cell array along the root longitudinal axis in Arabidopsis thaliana. The model qualitatively simulates auxin distribution over the longitudinal axis in intact roots, changes in this distribution at decreased auxin transport rates, and restoration of the auxin distribution pattern with subsequent establishment of new root meristem in the course of root regeneration after the ablation of its tip. The model shows the presence of different auxin distribution patterns over the longitudinal root axis and suggests possible scenarios for root growth and lateral root formation. Biological interpretation of different regimes of model behavior is presented. Russian Journal of Developmental Biology Springer Journals
