Проаналізовано рівень поліморфізму ділянок ДНК, фланкованих інвертованими LTR повторами ретротранспозонів, у генетично модифікованих рослин пшениці, отриманих методом Agrobacterium-опосередкованої трансформації в культурі in vitro, що містять ген орнітинамінотрансферази. Найбільш результативним було застосування праймера до ретротранспозону Sukkula, де в спектрі продуктів ампліфікації ДНК отримали чотири нові амплікони у дев’яти досліджених рослин. Ці дані підтвердили, що саме інсерція чужорідної ДНК здатна індукувати транспозицію ретротранспозонів Sukkula/Nikita тa Wham/Sabrina, оскільки у контрольних рослин, отриманих у культурі in vitro, їх активність не встановлена.
Ключові слова: Triticum aestivum, Agrobacterium-опосередкована трансформація, ретротранспозони, IRAP-ПЛР
