Abstract
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 that 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 is provided for enhancing biotin levels by introducing into plant tissue a chimeric gene capable of expressing a biotin biosynthetic enzyme such as biotin synthase. Thus, transgenic plant tissue, including whole plants, having enhanced levels of biotin is likewise provided.
