An Arabidopsis acetyl-CoA carboxylase (ACCase) gene has been isolated and sequenced. The 10 kb gene encodes a 251 kD cytosolic ACCase isozyme. The nucleic acid sequence of the gene is set forth in SEQ ID No. 1 and has been accorded GenBank Accession No. L27074. The cDNA sequence and deduced amino acid sequence of the cDNA are set forth in SEQ ID Nos. 2 and 3, respectively. By controlling expression of the gene of the present invention, carboxylation of acetyl-CoA to produce malonyl-CoA may be controlled. Thus, by introducing constructs of the gene of the present invention in sense or anti-sense orientation, carboxylation of acetyl-CoA to produce malonyl-CoA may be increased or decreased. Consequently, fatty acid synthesis and elongation in plants and seeds which depends on malonyl-CoA may also be controlled.
