Abstract

La présente invention apporte une solution à la problématique de la surexpression de constituants chimiques chez des végétaux. L'invention concerne un procédé permettant d'obtenir des végétaux modifiés ayant une efficacité de régénération accrue, et rendant possible la surexpression de constituants chimiques chez des végétaux, de préférence la sapogénine stéroïdique, la diosgénine chez Dioscorea prazeri. Le procédé comprend une modification génétique médiée par Agrobacterium tumeficians.
