Abstract
"PLANTAS TRANSGêNICAS COM TOCOFEROL METILTRANSFERASE" São descritas seq³ências de genes que codificam gama-tocoferol metiltransferases a partir de organismos fotossintéticos. A enzima gama-tocoferol metiltransferase catalisa a metilação de gama-tocoferol para produzir alfa-tocoferol, que é a espécie de tocoferol mais bioativa. Acredita-se que gama-tocoferol metiltransferase esteja envolvida em regular as quantidades relativas dos vários tocoferóis presentes em organismos fotossintéticos. Ao introduzir uma construção genética possuindo uma seq³ência que codifica a gama-tocoferol metiltransferase colocada sob o controle de um promotor de planta em uma planta, plantas transgênicas podem ser feitas possuindo expressão gama-tocoferol metiltransferase alterada, para obter mudanças dramáticas no perfil de tocoferol da planta. Plantas transgênicas podem ser produzidas possuindo alfa-tocoferol como o tocoferol predominante em suas sementes e óleos.
