Regulation of plant growth and development by auxin is mediated by the hormone controlled distribution and dose-dependent mechanisms of its action. A mathematical model is proposed, which described the distribution of auxin in the cells extending along the central axis of the Arabidopsis thaliana root. This model reproduces qualitatively both auxin distribution in cells of the root central axis under the normal conditions and under the conditions of decreased active transport and the recovery of auxin distribution and related meristem restoration during root regeneration after ablation of its tip. Different types of distribution of the auxin concentration over the vertical root axis are described, possible variants of root growth and lateral roots formation are proposed, and biological interpretation is given to different regimes of model behavior.
生长素对植物生长和发育的调控是通过激素控制的分布及其作用的剂量依赖性机制介导的。本文提出了一个数学模型，该模型描述了生长素在沿拟南芥根中轴线延伸的细胞中的分布。该模型定性地再现了正常条件下以及主动运输减少时根中轴线细胞中的生长素分布，以及根尖切除后根再生过程中生长素分布的恢复和相关分生组织的恢复。描述了生长素浓度在垂直根轴上的不同分布类型，提出了根生长和侧根形成的可能变体，并对模型行为的不同状态进行了生物学解释。
