    • The present invention reveals that biotin biosynthesis in a plant is enhanced when the level of one or more of the enzymes in the plant biotin biosynthetic pathway is increased. Based upon this revelation methods which increase the level of one or more biotin biosynthetic enzymes in plant tissue are provided as a means for achieving enhanced levels of biotin in plant tissue. In particular, a method for enhancing biotin levels by introducing a chimeric gene capable of expressing a biotin biosynthetic enzyme into plant tissue is provided. Resulting transgenic plant tissue, including whole plants, having enhanced levels of biotin are also provided.
    • 本发明揭示当植物生物素生物合成途径中的一种或多种酶的水平增加时,植物中的生物素生物合成增强。 基于提高植物组织中一种或多种生物素生物合成酶水平的这种启示方法,作为在植物组织中达到提高生物素水平的手段。 特别地,提供了通过将能够表达生物素生物合成酶的嵌合基因导入植物组织来提高生物素水平的方法。 还提供了具有增强的生物素水平的所得转基因植物组织,包括整株植物。
