РЕОРГАНИЗАЦИЯ ГЕНОМА РАСТЕНИЙ В ХОДЕ АЛЛОПОЛИПЛОИДИЗАЦИИ
Аннотация
Рассмотрены молекулярно-генетические механизмы реорганизации генома растений в процессе аллополиплоидизации. Подчеркнута особая роль ранних генетических изменений, изучение которых проводилось с использованием уникальной модели синтетических аллополиплоидов. Обобщены данные о различных геномных изменениях на ранних стадиях аллополиплоидизации, включающих активацию мобильных элементов, хромосомные перестройки, эпигенетические и транскриптомные изменения и др. Отмечено важное значение этих изменений в формировании устойчивой организации аллополиплоидного генома, обеспечивающей эволюционный успех и распространенность аллополиплоидов среди высших растений.
