CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is a division of U.S. application Ser. No. 10 / 089,281, which is the U.S. National Stage of International Application No. PCT / US00 / 26963, filed Sep. 29, 2000, which claims the benefit of U.S. Provisional Application Ser. No. 60 / 156,807, filed Sep. 29, 1999; all of which are hereby incorporated herein by reference in their entirety.FIELD OF THE INVENTION

[0002] The present invention relates to the genetic manipulation of plants for the production of biodegradable thermoplastics, particularly polyhydroxyalkanoate copolymers. BACKGROUND OF THE INVENTION

[0003] Composed of polymers of a variety of organic compounds, plastics can be molded, extruded, cast into various shapes and films, and even drawn into fibers. It is such versatility that has led to incorporation of plastics into a seemingly endless number of products. Thus, plastic products have become an integral part of everyday life in industrialized society, and the de...
