The present invention relates to a method to reduce glucosinolate production and/or accumulation in plants wherein a reduced glucosinolate content is desired, particularly in the seeds of these plants. In accordance with the present invention, chimeric gene constructs inhibiting an enzyme responsible for glucosinolate production, the enzyme UDP-glucose:thiohydroximate S-glucosyltransferase (further referred to as "S-GT") are provided. Further in accordance with the present invention, plants are provided having substantially lower glucosinolate levels in their tissues, particularly in their seeds, which permit a significant expansion of the germplasm basis for the breeding of new oilseed rape varieties having lower glucosinolate levels, particularly in their seeds.
本发明涉及一种减少植物中葡萄糖苷酸的产生和/或积累的方法,在这种植物中,特别是在这些植物的种子中,需要减少葡萄糖苷酸的含量。根据本发明,提供了抑制负责葡萄糖苷酸生产的酶 UDP-葡萄糖:硫代羟基 S-葡萄糖基转移酶(进一步称为 "S-GT")的嵌合基因构建体。此外,根据本发明,所提供的植物在其组织中,特别是在其种子中的葡萄糖苷酸含量大大降低,这使得培育具有较低葡萄糖苷酸含量,特别是种子中葡萄糖苷酸含量较低的油菜新品种的种质基础得以显著扩大。
