КЛЮЧЕВАЯ РОЛЬ PIN-БЕЛКОВ В ТРАНСПОРТЕ АУКСИНА В КОРНЕ ARABIDOPSIS THALIANA L.

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.
