cDNA clones encoding the fatty-acid- biosynthetic enzyme NADPH-linked 3-oxoacyl-(acyl carrier protein) (ACP) reductase were isolated from a Brassica napus (rape) developing seed library and from an Arabidopsis thaliana (thale cress) leaf library. The N-terminal end of the coding region shows features typical of a stromal-targeting plastid-transit peptide. The deduced amino acid sequences have 41% and 55% identity respectively with the nodG-gene product of Rhizobium meliloti, one of the host-specific genes that restrict infectivity of this bacterium to a small range of host plants. The probability that the nodG-gene product is a oxoreductase strengthens the hypothesis that some of the host-specific nod-gene products are enzymes which synthesize polyketides that uniquely modify the Rhizobium nodulation signal molecule.

One independent and two overlapping rape cDNA clones have been isolated from a rape embryo library. We have shown that they encode a 2.3 kb and a 2.5 kb stretch of the full-length acetyl-CoA carboxylase (ACCase) cDNA, corresponding to the biotin-binding and transcarboxylase domains respectively. Using the cDNA in Northern-blot analysis we have shown that the mRNA for ACCase has a higher level of expression in rape seed than in rape leaf and has a full length of 7.5 kb. The level of expression during rape embryogenesis was compared with both oil deposition and expression of two fatty acid synthetase components enoyl-(acyl-carrier-protein) reductase and 3-oxoacyl-(acyl-carrier-protein) reductase. Levels of ACCase mRNA were shown to peak at 29 days after anthesis during embryonic development, similarly to enoyl-(acyl-carrier-protein) reductase and 3-oxoacyl-(acyl-carrier-protein) reductase mRNA. In addition, a full-length genomic clone (19 kb) of Arabidopsis ACCase has been isolated and partially sequenced. Analysis of the clone has allowed the first plant ACCase activity domains (biotin carboxylase-biotin binding-transcarboxylase) to be ordered and assigned. Southern-blot analysis using the Arabidopsis clone indicates that ACCase is a single-copy gene in Arabidopsis but is encoded by a small gene family in rape.
