Studying of auxin (phytohormone) transport kinetics has a key role inunderstanding of plant growth regulation. Mathematical modellingmakes it possible to characterize auxin transport in details, but it is mainly aimed atthelevel of plant tissue. Characterization of auxin kinetics on cellular level could, therefore, become an important source of information for further studies. The aim of this work is characterization of 2,4-D (synthetic auxin) uptake parameters intobacco cells by means of single cell level modelling. Accumulation experiments withradiolabeled 2,4-D and different combinations of auxin transport inhibitors (NPA andCHPAA) allow us to describe auxin flow both into and from the cell. New mathematical model of auxin transport onthecellular level is derived from existing models andtheparameters ofauxin transport are characterized. Validation of the new model proves its ability topredict experimental data and shows the possibility of its further use....

Mathematical modeling is now often used as a tool to study the transport of plant hormones auxins which are responsible for regulation of many physiological processes in plants. Present models are, however, simplified and they do not represent the structure of the real system precisely. In this thesis a detailed approach to the subject of auxin transport modeling is therefore proposed suggesting use of various types of experimental data for step-wise construction of the model via separate characterization of individual auxin transport processes (analysis-synthesis approach). The experimental data, produced mainly by accumulation assays and HPLC metabolic profiling using radiolabeled auxins, provided valuable findings about the characteristics of auxin transport on single-cell level. At first, previously proposed mathematical model of auxin diffusion through a cell was invalidated and a significant effect of NAA metabolism on experimental results and NAA transport itself was proved. NAA metabolism was then closely characterized and based on obtained results a method of its elimination was proposed for the needs of future measurements. As a demonstration, some of the findings were used during construction and implementation of a mathematical model of auxin flux through a boundary of two adjacent cells. Analysis of the model and of its simulation results shows the model's potential for future development and for the study of regulatory mechanisms of active auxin transport. The suggested approach to the study of auxin transport processes by means of mathematical modeling was proved to be able to interpret experimental data on one side and to construct complex models of auxin transport on the other....
