Abstract
The invention relates to the genes encoding 3-oxoacyl-[acyl carrier protein(ACP)] reductase (OAR). Compositions and methods for producing polyhydroxyalkanoate in transformed plants and transformed host cells are provided. Such methods find use in producing biodegradable thermoplastics in host cells and plants. Isolated nucleotide molecules, expression cassettes, isolated polypeptides and genetically manipulated host cells, plants, plant tissues, plant cells and seeds are also provided.
Claims10
An isolated nucleic acid molecule comprising a nucleotide sequence selected from the group consisting of:
- (a) a nucleotide sequence comprising the nucleotide sequence set forth in SEQ ID NO:
- 1;
- (b) a nucleotide sequence which encodes a polypeptide having the amino acid sequence set forth in SEQ ID NO:
- 2;
- (c) a nucleotide sequence having at least 95% sequence identity to the nucleotide sequence set forth in SEQ ID NO:
- 1, wherein said nucleotide sequence encodes a polypeptide comprising 3-oxoacyl-[acyl carrier protein] reductase (OAR) activity;
- and
- (d) a nucleotide sequence fully complementary to a nucleotide sequence of (a), (b), or (c).
A transgenic plant comprising in its genome a stably integrated nucleotide construct comprising a nucleic acid molecule operably linked to a promoter that drives expression in a plant cell, wherein said nucleic acid molecule comprises a first nucleotide sequence selected from the group consisting of:
- (a) a nucleotide sequence comprising the nucleotide sequence set forth in SEQ ID NO:
- 1;
- (b) a nucleotide sequence which encodes a polypeptide having the amino acid sequence set forth in SEQ ID NO:
- 2;
- (c) a nucleotide sequence having at least 95% sequence identity to the nucleotide sequence set forth in SEQ ID NO:
- 1, wherein said nucleotide sequence encodes a polypeptide comprising OAR activity;
- and
- (d) a nucleotide sequence fully complementary to a nucleotide sequence of (a), (b), or (c).
