Вид симметрии отражает характерное взаимное расположение пучков сосудистых тканей флоэмы и ксилемы на поперечном срезе корня. Механизмы формирования различных типов симметрий в структуре центрального цилиндра остаются недостаточно исследованными. Предполагается, что процесс дифференцировки запускается и контролируется фитогормоном ауксином, который выступает в роли морфогена (Sachs, 1969). В работе представлена модель, описывающая транспорт ауксина через одноклеточный слой клеток поперечного среза корня. Изучены стационарные распределения концентраций гормона ауксина, которые могут устанавливаться в поперечном слое клеток. Показано, что нелинейные процессы регуляции транспорта ауксина способны обеспечить существование неравномерных распределений его концентраций, несущих целевую морфогенетическую информацию о диархной структуре цилиндра корня. Однако целевые морфогенетические поля всегда сосуществуют с равномерными распределениями, в которых морфогенетическая информация отсутствует. Полученные результаты свидетельствуют в пользу гипотезы о том, что одним из механизмов формирования целевого распределения концентрации ауксина в клетках поперечного слоя корня может быть неравномерный поток ауксина соответствующей конфигурации из побега в корень.</p></abstract><trans-abstract xml:lang="en"><p>Plants differ in the types of the root central cylinder: diarch, triarch, tetrarch, pentarch, or polyarch. The type of the symmetry is the reflection of the relative positions of xylem and phloem bundles in a cross section of the root. The mechanisms forming different types of symmetries in the central cylinder remain poorly understood. It is assumed that vasculature differentiation is triggered and controlled by plant hormone auxin (Sachs, 1969). We have developed a model that describes auxin flow through a cell layer, imitating a cross section of the vascular cylinder in a root. We have studied the stationary distributions of auxin in the cell layer depending on the model parameters. It is shown that the nonlinear processes of auxin transport regulation are responsible for the formation of asymmetric auxin distributions, which may be interpreted as the positional information for development of the diarch structure of the vascular cylinder. However, these distributions always coexist with uniform stationary distributions, not providing positional information. It is hypothesized that the most likely factor in the formation of the final auxin distribution in a root section is an appropriate geometry of the auxin flow from the shoot to the root.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>моделирование</kwd><kwd>морфоген</kwd><kwd>ауксин</kwd><kwd>корень</kwd><kwd>дифференцировка сосудистых тканей растений</kwd><kwd>флоэма</kwd><kwd>ксилема</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mathematical modeling</kwd><kwd>morphogen</kwd><kwd>auxin</kwd><kwd>root</kwd><kwd>vascular tissue differentiation</kwd><kwd>phloem</kwd><kwd>xylem</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>РФФИ, СО РАН, Фонд "Династия", бюджетный проект VI.61.1.2</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Лихошвай В.А., Омельянчук Н.А., Миронова В.В. и др.
