We have characterized the occurrence and expression of multiple acyl carrier protein (ACP) isoforms in Arabidopsis thaliana (L.) Heynh ecotype Columbia. Immunoblot analysis of ACPs from Arabidopsis tissues separated by native polyacrylamide gel electrophoresis and 1 molar urea polyacrylamide gel electrophoresis revealed a complex pattern of multiple ACP isoforms. All tissues examined (leaves, roots, and seeds) expressed at least three forms of ACP. The immunoblot identifications of ACP bands were confirmed by acylation of ACP extracts with Escherichia coli acyl-ACP synthetase. A full-length cDNA clone has been isolated that has 70% identity with a previously characterized Arabidopsis genomic ACP clone (ACP-1) (MA Post-Beittenmiller, A Hlousek-Radojci?, JB Ohlrogge [1989] Nucleic Acids Res 17: 1777). Based on RNA blot analysis, the cDNA clone represents an ACP that is expressed in leaves, seeds, and roots. In order to identify the protein products of each known ACP gene, their mature coding sequences have been expressed in E. coli. Using polymerase chain reactions, exons II and III of the genomic ACP-1 clone and the mature coding sequences of the ACP-2 cDNA clone were subcloned into E. coli expression vectors. Site-directed mutagenesis was used to convert the amino acid sequence of the ACP-2 cDNA clone to that of the A2 clone of Lamppa and Jacks ([1991] Plant Mol Biol 16: 469-474), ACP-3. The three E. coli-expressed proteins have different mobilities on polyacrylamide gel electrophoresis gels and each comigrates with a different Arabidopsis ACP isoform expressed in leaves, seeds, and roots. Thus, all of the three cloned ACPs appear to be constitutively expressed Arabidopsis ACPs. In addition to these three ACP isoforms, protein blots indicate that seed, leaf, and root each express one or more tissue-specific isoforms.
