Фитогормон ауксин является ключевым фактором морфогенеза растений. Ауксин неравномерно распределяется в тканях растения, формируя градиенты и максимумы концентраций, в соответствии с которыми происходит рост, деление и дифференцировка клеток. Основной вклад в образование градиентов ауксина вносит семейство PIN-FORMED (PIN) белков, трансмембранных транспортеров ауксина. Корень растений представляет собой наиболее удобную модель для изучения регуляции морфогенеза ввиду его достаточно простой клеточной организации. В данном обзоре мы рассматриваем особенности экспрессии PIN транспортеров и их роль в формировании распределения ауксина в корне арабидопсиса. Обсуждаются математические модели, которые позволили доказать связь между паттерном экспрессии PIN-белков и распределением ауксина в меристеме корня.

The phytohormone auxin is the key factor in plant morphogenesis. Being unevenly distributed in plant tissues, it forms gradients and concentration maxim а, according to which cells grow, divide, and differentiate. The family of PIN-FORMED (PIN) proteins, transmembrane transporters of auxin, play the key role in the formation of auxin gradients. The plant root is the most appropriate model for studying the regulation of morphogenesis, because of its relatively simple cellular organization. This review concerns the expression patterns of PIN transporters and their contribution to auxin distribution in the root of Arabidopsis. Mathematical models that prove the relationship between the expression pattern of PIN proteins and auxin distribution in the root meristem are discussed.
