du Pont obtains United States patent.

E. I. du Pont de Nemours & Company (Wilmington, DE) has patented isolation of nucleic acid fragments from plants or fungi that encode lumazine synthase (LS) protein. The invention also relates to the isolation of nucleic acid fragments from plants or fungi that encode riboflavin synthase (RS) protein. In addition, the invention also relates to the construction of chimeric genes encoding all of a portion of LS, in sense or antisense orientation, wherein the expression of the chimeric gene results in production of altered levels of plant LS in a transformed host cell. Furthermore, the invention also relates to the construction of chimeric genes encoding all of a portion of RS, in sense or antisense orientation, wherein the expression of the chimeric gene results in production of altered levels of plant or fungal RS in a transformed host cell. In vivo and in vitro methods to identify herbicide or fungicide candidates are included that evaluate the ability of a chemical compound to inhibit the activity of a plant or fungal LS enzyme or a plant or fungal RS enzyme.
