Title (EN) A METHOD FOR OVER EXPRESSION OF CHEMICAL CONSTITUENTS IN PLANTS
(FR) PROCÉDÉ PERMETTANT LA SUREXPRESSION DE CONSTITUANTS CHIMIQUES CHEZ DES VÉGÉTAUX
Abstract:
(EN) The present invention provides a solution to the problem involved in over expression of chemical constituents in plants. It provides a method for attaining transformed plants with higher regeneration efficiency with the potential t over express chemical constituents in plants, preferably Steroid sapogenin, diosgenin in Dioscorea prazeri. The method involves Agrobacterium tumeficans mediated gene transformation of HMG-CoA reductase genes.
(FR) 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.
