Patent number: 8022269Abstract: The present invention relates to methods for increasing the yield of a compound produced by an organism. More particularly, the present invention relates to methods for increasing the total or soluble carbohydrate content or sweetness or increasing the content of an endogenous carbohydrate of a plant tissue by producing a sugar-metabolizing enzyme that catalyzes the conversion of an endogenous sugar (one that is normally produced in the plant) to an alien sugar (one that is not normally produced in the plant at the same developmental stage). The invention also relates to plants and plant parts that produce a sugar-metabolizing enzyme to yield an alien sugar, with the consequence of higher total fermentable carbohydrate content, and to fermentable carbohydrates and other products derived therefrom.Type: GrantFiled: October 11, 2006Date of Patent: September 20, 2011Assignee: The University of QueenslandInventors: Robert George Birch, Luguang Wu
