Abstract:
A method for generating a transformed plant which produces a polyhydroxyalkanoate polymer having a single mode molecular weight distribution, comprising the steps of:(a) inserting into plant cells a nucleic acid molecule encoding a .beta.-ketoacyl reductase, a nucleic acid molecule encoding a .beta.-ketothiolase, and a nucleic acid molecule encoding a polyhydroxyalkanoate synthase to produce transformed plant cells, wherein the transformed plant cells comprise a single copy of the nucleic acid molecule encoding a polyhydroxyalkanoate synthase;(b) isolating transformed plant cells;(c) regenerating the transformed plant cells to form transformed plants; and(d) selecting a transformed plant which produces a polyhydroxyalkanoate polymer having a single mode molecular weight distribution; wherein the molecular weight distribution is between about 2 and about 4.
