Резюме

Мы описали структуру четырех различных клТ-ДНК N. tomentosiformis, являющегося предковой формой N. tabacum, и обнаружили несколько интактных ORF. Среди них TB-mas2’ и TA-rolC были тестированы на функциональность. TB-mas2’ кодирует фермент синтеза дезоксифруктозилглутамина (DFG). Некоторые сорта N. tabacum характеризуются очень высоким уровнем экспрессии TB-mas2’ и образуют DFG в корнях. TA-rolC биологически активен и будучи экспрессирован под контролем сильного конститутивного промотора вызывает изменения ростовых характеристик N. tabacum. Основываясь на данных о структуре и функции клТ-ДНК предожена теоретическая модель происхождения и эволюции природно-трансгенных растений, которая может быть использована при планировании последующих исследований.
