Abstract:
The present biotechnological approach for the production of polyhydroxyalkanotes (PHAs) uses microbial systems. The high production costs makes them substantially more expensive than synthetic plastics. Engineering a novel pathway in eucaryotic cell systems is a beneficial alternative to the production of PHAs in bacteria. This pathway will initially produce free (C 8 ) fatty acids from the fatty acid synthetic pathway through the action of thioesterase, that will then add a CoA moiety to the free fatty acid through the action of an acyl-CoA synthetase, that will produce 3-ketoacyl-CoAs from the acyl-CoA through the action of a thiolase, that will produce R-(−)-OH-acyl-CoAs from the 3-keto acid CoAs through the action of a dehydrogenase isoform from yeasts. These R-(−)-3-OH-acyl-CoAs will finally be used as substrate for the PHA synthase reaction.

Description:
The present application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/124,417, filed Mar. 15, 1999. 
    
    
     The present invention relates to method for producing polyhydroxyalkanoates in recombinant organisms. 
     BACKGROUND OF THE INVENTION 
     Plastic materials have become an integral part of contemporary life because they possess many desirable properties, including durability and resistance to degradation. Over the past 10-20 years, their widespread use have been increasingly regarded as a source of environmental and waste management problems. Industrial societies are now more aware of the impact of discarded plastic on the environment, and of their deleterious effect on wildlife and the aesthetic qualities of cities and forests. Problems associated with the disposal of waste and reduction in the availability of landfills have also focused attention on plastics, which accumulate in the environment at a rate of 25 million tonnes per year (Lee, 1996). These problems have created much interest in the development and production of biodegradable plastics. Biodegradable polymers are composed of material which can be degraded either by non-enzymatic hydrolysis or by the action of enzymes secreted by microorganisms. Estimates of the current global market for these biodegradable plastics range up to 1.3 billion kg per year (Lindsay, 1992). 
     Among the various biodegradable plastics available, there is a growing interest in the group of polyhydroxyalkanoates (PHAs). These are natural polymers produced by a variety of bacteria and they are 100% biodegradable. By changing the carbon source and bacterial strains used in the fermentation processes, PHA-biopolymers having a wide variety of mechanical properties have been produced. Their physical characteristics range from hard crystalline to elastic, depending on the composition of monomer units (Anderson &amp; Dawes, 1990). The majority of PHAs are composed of R-(−)-3-hydroxyalkanoic acid monomers ranging from 3 to 14 carbons in length (C3-C14). The simplest member of the family, P(3HB) (C4), is highly crystalline, relatively stiff, and becomes brittle over a period of days upon storage under ambient conditions (Barham et al., 1984; De Koning et al., 1992; Doi, 1990; Holmes, 1988). Therefore, attempts have been made to decrease the brittleness of P(3HB) either by incorporating comonomers such as P(3HV), by blending with other polymers or blending with chemically synthesized atactic P(3HB) (Holmes, 1988; Kumagai &amp; Doi, 1992 a, 1992 b, 1992 c; Pearce &amp; Marchessault, 1994). 
     The P(3HB-co-3HV) copolymer, developed by ZENECA under the tradename BIOPOL™, has improved mechanical properties compared to P(3HB). As the fraction of P(3HV) (C5) increases, the polymer becomes tougher, more flexible and have an higher elongation to break (Doi et al., 1990). The medium-chain-length (MCL) PHAs are semicrystalline elastomers with a low melting point, low tensile strength, and high elongation to break. They thus have physico-chemical characteristics that make them more appealing than homogeneous P(3HB); they can even be used as a biodegradable rubber after cross linking by electron-beam irradiation (De Koning et al., 1994; Gagnon et al., 1992; Gross et al., 1989; Preusting et al., 1990). 
     PHAs have been shown to occur in over 90 genera of Gram-positive and Gram-negative bacteria species (Steinbüchel, 1991). Over 40 different PHAs have been characterized, with some polymers containing unsaturated bonds or various functional groups (Steinbüchel, 1991). Bacteria synthetise and accumulate PHAs as carbon and energy storage materials or as a sink for redundant reducing power under the condition of limiting nutrients in the presence of excess carbon sources (Byrom, 1994; Doi, 1990; Steinbüchel &amp; Valentin, 1995). When the supply of the limiting nutrient is restored, the PHAs are degraded by intracellular depolymerases and subsequently metabolized as carbon and energy source (Byrom, 1990; Doi, 1990). The monomer 3HAs released from degradation of these microbial polyesters are all in the R-(−)-configuration due to the stereo specificity of biosynthetic enzymes (Anderson &amp; Dawes, 1990). The molecular weights of polymers are in the range of 2×10 5  to 3×10 6  Daltons, depending on the microorganism and growth condition (Byrom, 1994). PHAs accumulate in the cells as discrete granules, the number per cell and size of which can vary among the different species; 8 to 13 granules per cell of 0.2 to 0.5 μm diameter have been observed in  Alcaligenes eutrophus  (Byrom, 1994). 
     PHAs can be subdivided in two groups depending on the number of carbon atoms in the monomer units: short-chain-length-(SCL) PHAs, which contain 3-5 carbon atoms, and medium-chain-length-(MCL) PHAs, which contain 6-14 carbon atoms (Anderson &amp; Dawes, 1990). This is mainly due to the substrate specificity of the PHA synthases that can only accept 3HA monomers of a certain range of carbon lengths (Anderson &amp; Dawes, 1990). The PHA synthase of  Alcaligenes eutrophus  can polymerize C3-C5 monomers, but not C6 or higher. On the other hand, the PHA synthase of  Pseudomonas oleovorans  only accepts C6-C14 monomers. Of particular interest is the capacity of some PHA synthase to polymerize 3-hydroxy-, 4-hydroxy- and 5-hydroxy-alkanoates (Steinbüchel &amp; Schlegel, 1991). Even though most of the PHA synthases examined to date are specific for the synthesis of either SCL- or MCL-PHAs, at least six cases were recently reported in which the bacteria were able to synthesize copolymer consisting of SCL and MCL units (Lee, 1996). 
     P(3HB) is the most widespread and thoroughly characterized PHA, and most of the knowledge has been obtained from  Alcaligenes eutrophus  (Steinbüchel, 1991). In this bacterium, P(3HB) is synthesized from acetyl-CoA by the sequential action of three enzymes (FIG.  1 ).The first one, 3-ketothiolase, catalyses the reversible condensation of two acetyl-CoA moieties to form acetoacetyl-CoA. Acetoacetyl-CoA reductase subsequently reduces acetoacetyl-CoA to R-(−)-3-hydroxybutyryl-CoA, which is then polymerized by the action of PHA synthase to form P(3HB). A number of PHAs with different C3 to C5 monomers have been produced in  A. eutrophus , the nature and proportion of these monomers being influenced by the type and relative quantity of the carbon sources supplied to the growth media (Steinbüchel &amp; Valentin, 1995).  Pseudomonas oleovorans  and most pseudomonades belonging to the ribosomal rRNA homology group I synthesize MCL-PHAs from various MCL-alkanes, alkanols, or alkanoates (Steinbüchel &amp; Valentin, 1995). The composition of PHA produced is related to the substrate used for growth, with the polymer being mostly composed of monomers which are 2n carbons shorter than the substrates used. It was suggested that the acyl-CoA derived from alkanoic acids enter the β-oxidation pathway and R-(−)-3hydroxyacyl-CoA intermediates used by the PHA synthase are generated either through reduction of 3-ketoacyl-CoA by a ketoacyl-CoA reductase, conversion of S-(+)-3hydroxyacyl-CoA normally produced by the pathway to the R-(−)-isomer by an epimerase, or the direct hydration of enoyl-CoA by an enoyl-CoA hydratase (Poirier et al., 1995). 
     Most pseudomonades belonging to rRNA homology group I, except  P. oleovorans , also synthesize MCL-PHAs when grown on substrates non related to fatty acids and alkanoates, such as gluconate, lactate, glycerol, and hexoses (Anderson &amp; Dawes, 1990; Huijberts et al., 1994; Timm &amp; Steinbüchel, 1990). These substrates must be first converted into acetyl-CoA to be used for the PHAs biosynthesis. This suggests that, in theory, microorganisms, plants and even animals, must be able to synthesize PHA following the transfection of a limited number of genes. In these bacteria, three main pathways have been proposed for the synthesis of PHA precursors (Huijberts et al., 1992, 1994). 
     (i) A detailed analysis of the composition of PHA produced by  P. putida  grown on glucose have shown that the monomers are structurally identical to the acyl-moieties of the 3-hydroxyacyl-ACP intermediates of the novo fatty acid biosynthesis. Since it has not been shown that PHA synthase can accept acyl-ACPs as substrates, these must therefore be converted to acyl-CoAs by a transacylase before entering the PHA pathway. 
     (ii) Fatty acid degradation by β-oxidation is the main pathway when fatty acids are used as substrate. 
     (iii) It has been found that some of the monomeric units of PHA are one C2 unit longer than the fatty acid used as substrate. Chain elongation by condensation of an acetyl-CoA to the acyl-CoA has therefore been suggested. 
     A complex picture thus emerges in which the steps linking the different pathways implied and PHA synthesis are at present unknown (FIG.  2 ). It is assumed, but not demonstrated, that the ultimate substrate for polymerization is the R form of the CoA-activated 3-hydroxy fatty acid intermediates. Expression of the synthases of  P. putida  in wild-type  E. coli  is not sufficient to produce PHA in this bacterium (Huisman, 1991). More genetic information from Pseudomonas spp. seems to be needed to enable PHA synthesis in  Escherichia coli . We can speculate that the missing step in prokaryotic organisms other than pseudomonades is the formation of R-(−)-3-OH-acyl-CoA of more than 5C. 
     The bio(techno)logical approach for the production of PHAs use microbial systems. The major commercial drawback of the so-produced bacterial PHAs are their high production cost, making them substantially more expensive than synthetic plastics. At present, Zeneca produces approximately 1,000 tons per year of P(3HB-co-3HV) copolymer at a cost of approximately $16/kg. At a production rate of 10,000 tons per year or more, the most optimistic scenario would put the cost at $5/kg. With the cost of many synthetic plastics such as polypropylene and polyethylene, being less than $1/kg, PHA appear too costly for most low-value consumer products (Poirier et al., 1995). 
     Engineering of novel pathways in eucaryotic cell systems seems to be a beneficial alternative to the production of PHAs in bacteria. On one hand, yeast and insect cells can be used as models to gain information on PHAs synthesis in eucaryotes (Hahn et al., 1996; Sherman, 1996). On the other hand, a new possibility for the production of PHAs on a large scale and at costs comparable to synthetic plastics has arisen from the demonstration of their production in transgenic plants (Poirier et al., 1992). Production of PHA on an agronomic scale could allow synthesis of biodegradable plastics in the million ton scale compared to fermentation which produces material in the thousand ton scale (Poirier et al., 1995). In addition, plant production of PHAs would use carbon dioxide, water and sunlight as raw materials to produce PHA in an environmentally friendly and sustainable manner. 
     Synthesis of PHB in plants was initially explored by expression of the PHB biosynthetic genes of  A. eutrophus  in the plant  Arabidopsis thaliana  (Poirier et al., 1992). Although of no agricultural importance, this small oil seed plant was chosen for its extensive use as a model system for genetic and molecular studies in plants. These plants accumulated P(3HB) granules that were 0.2 to 0.5 μm in diameter in the nucleus, vacuole, and cytoplasm. However, the amount of P(3HB) accumulated was only 100 μg/g fresh weight. Furthermore, plants were impaired in their growth, probably due to the severe deviation of substrate from the mevalonate pathway which is essential for chlorophyll synthesis. 
     To avoid this problem and to improve polymer accumulation, further genetic manipulation have been carried out to divert reduced carbon away from endogenous metabolic pathways and to regulate the tissue specificity and timing of gene expression. The plastid was suggested to be the ideal location for P(3HB) accumulation because it is the location of high flux of carbon through acetyl-CoA. Genetically engineered genes of  A. eutrophus  were then successfully targeted to the plant plastids, where the enzymes were active (Nawrath et al., 1995). The  A. eutrophus  PHA biosynthesis genes were modified for plastid targeting by fusing the transit peptide of ribulose biphosphate carboxylase to their N-terminal ends and were put under the control of the constitutive CaMV 35S promoter. The hybrid expressing the  A. eutrophus  PHA synthesis enzymes accumulated P(3HB) up to 10 mg/g fresh weight, representing ca. 14% of dry weight. 
     The knowledge acquired in this study is not only useful to optimise strategies for the production of PHB in recombinant organisms, but could also be used for the production of PHAs other than PHB, for example MCL-PHAs. For plant production of PHAs to become commercially viable, the genes must be transfected into a suitable plant species which has the agronomic properties to provide high yields of PHA per hectare, at unlimited scale and at economic prices. Subcellular localization signals and promoters must be chosen which allow the enzymes utilized to intercept the desired plant metabolites for incorporation into the polymer. 
     Different strategies have been proposed for production of PHAs in plants. Substitution of cytoplasmic oil bodies by PHA granules, production of PHAs in glyoxysomes or production of PHAs in leucoplasts have been proposed to be carried out in lipid-accumulating tissues of oilseed crops, such as seed endosperm or fruit mesocarp (van der Leij &amp; Witholt, 1995; Hahn et al., 1996; Srienc &amp; Leaf, 1996). In this tissue, triglycerides provide energy and carbon for germination of the new plant before establishment of photosynthesis. In contrast, PHAs would not be degraded in plants because of the absence of endogenous enzymes capable of hydrolyzing the polymer. Interfering with synthesis and degradation of fatty acids, in respectively plastids and glyoxysomes, by diverting energy into PHAs in this stage of development is likely to impair germination and/or seedling growth. As a post-harvest event this can be desirable. However, this inherent characteristic of the proposed strategy will create problems in the production of viable hybrid seeds. The expression of the enzymes during germination should be restricted to the second generation of seeds or fruit. For this, solutions will have to be found. It is probable that controlled expression of these genes will necessitate the use of promoters stimulated by external signals (Williams et al., 1992). 
     Plastids are regarded as the most amenable targets for PHA production. The production in chloroplasts, directly coupled to the novo fatty acid synthesis has many advantages. First, every important crop can be used. Second, in leaves, fatty acid metabolism is not as important as in seeds and targeting to this tissue is not likely to impair growth of the plant. Third, it is the most direct way for PHAs production, since the plant does not have to produce long-chain fatty acids or triglycerol before diverting fatty acid degradation products into PHAs, like in the case of glyoxysomal degradative mechanisms. Fourth, as shown for the synthesis of PHB, compartmentalization in plastids does not impair growth and then appear to be favoured over unrestricted synthesis in the cytosol. 
       Pseudomonas aeruginosa  belongs to the group of pseudomonades of the rRNA homology group I that synthesize MCL-PHAs when grown either on alkanes or on unrelated substrates such as gluconate (Timm &amp; Steinbüchel, 1990). A PHA synthase locus in  P. aeruginosa  was identified by the use of a  32 P-labeled 30-mer synthetic oligonucleotide probe, whose sequence design was based on that of a highly conserved region of PHA synthases in  A. eutrophus  and  P. oleovorans  (Steinbüchel et al., 1992). The organization of the locus consist of two genes coding for PHA synthases (phaC1, phaC2) separated by a gene coding for a putative PHA depolymerase (phaD), and a fourth gene (ORF3) downstream of phaC2 with an unknown function (Timm &amp; Steinbüchel, 1992). It has been shown that these synthases are similar to those found in  P. oleovorans , who is unable to synthesize MCL-PHAs from unrelated substrates (Huijberts et al., 1992). 
     As was shown in  P. aeruginosa , intermediates of fatty acid biosynthesis and β-oxidation are likely to contribute to the formation of PHA polymers. It is most likely that the intermediate precursors to PHA synthesis are either ketoacyl-CoA, S-(+)-3-OH-acyl-CoA, enoyl-CoA, or R-(−)-3-OH-acyl-ACP. However, since substrate specificity for PHA synthase has not yet been thoroughly tested, it is still unclear whether this enzyme could accept other derivative forms of 3-hydroxyacyl moieties, like for instance ACP derivatives. This can be of substantial impact on the choice of the best strategy for production in recombinant organisms: if the recombinant enzyme can accept, even at sub-optimum rates, ACP derivatives as substrate, then its targeting to chloroplasts would be the only required engineering alteration needed to induce PHA accumulation in leaf cells. 
     Monomeric units of PHAs, as it is the case for these of PHBs, are of the isomeric form R-(−)-; this has been repeatedly demonstrated by the analysis of hydrolysate from PHA granules. Enzymologic analysis also show that PHB synthases have a definite specificity for R-(−)-3-OH-acyl-CoA as substrates. Although the substrate specificity of PHA synthases has not yet been thoroughly characterized with purified enzyme preparations, their high homology with PHB syntheses and the analysis of their reaction product strongly suggest that they share a preference for R-(−)-3-OH-acyl CoA substrates with PHB synthases. 
     There are no demonstration of a metabolic pathway that would supply monomeric subunits to the polymerization reaction in Pseudomonades, nor in any other organisms. Known degradation pathways starting with acyl-CoAs produce S-(−)3-OH-acyl-CoAs and synthetic pathways produce R-(−)-acyl-ACPs, none of which can serve as substrate for the PHA synthesis reaction.

     DESCRIPTION OF PREFERRED EMBODIMENT 
     The present invention is directed at the production of polyhydroxyalkanoates in recombinant organisms, through the engineering of a new metabolic pathway which produces R-(−)-3-OH-acyl-CoAs monomeric subunits of adequate length to serve as substrates for the activity of PHA synthases. 
     More specifically, the present invention is directed to a methodology that is used to produce transgenic organisms with a new metabolic pathway that partially deviates fatty acids from their normal synthetic pathways, towards the formation of R-(−)-3-OH-acyl-CoAs that serves as substrates for the synthesis of hydroxyalkanoate polymers in chloroplasts. The new synthetic pathway of the present invention is depicted in FIG.  3 . 
     In one embodiment of the present invention the transgenic organism is a plant or any organ of a plant where there is active plastid activity. 
     According to the present invention examples of suitable plants include but are not limited to Arabidopsis, tobacco, alfalfa and tuber plants such as potato, sweet potato, beet and cassava. 
     Prior to the present invention, there was no demonstration of a metabolic pathway that would supply monomeric subunits to the polymerization reaction in Pseudomonades, nor in any other organisms. Known degradation pathways starting with acyl-CoAs produce S-(−)3-OH-acyl-CoAs and synthetic pathways produce R-(−)-acyl-ACPs, none of which can serve as substrate for the PHA synthesis reaction. Thus, the present invention is directed to a synthetic pathway that will produce R-(−)-OH-acyl-CoAs from 3-keto acid-CoAs through the action of a dehydrogenase isoform from yeast. These R-(−)-OH-acyl-CoAs will then serve as a substrate for the PHA synthase reaction. 
     According to the present invention the term polyhydroxyalkanoate, is intended to include a polymer of R-(−)-3-hydoxyalkanoic acid monomers from about 3 to about 14 carbons in length. In one embodiment of the present invention the PHA synthase from  Pseudamonas aeruginosa  is used in the last step of the synthetic pathway. This enzyme prefers R-(−)-3-OH-acyl-CoAs of C6 to C 14 as a substrate. 
     The biosynthetic pathway of the present invention involves five enzymes: a thioesterase, a acyl-CoA synthetase, a thiolase, a D-3-hydoxyacyl-CoA dehydrogenase and a PHA synthase. 
     The first reaction is catalyzed by a thioesterase. In one embodiment of the present invention the enzyme has been cloned from a cDNA library from  Cuphea hookeriana , a Mexican bush plant which accumulates up to 75% of C8:0- and C10:0-fatty acids in seeds. This clone Cl FatB2 (GenBank accession # U39834) has been expressed in  E. coli  where it exhibited a high specificity for C8:0 and C10:0-ACPs as substrates. In the chloroplasts, this enzyme removes C8- and C10-acyl-ACPs from the fatty acid synthetic pathway and releases free medium-chain length fatty acids in the stroma much as endogenous thioesterases do with C 16- and C18-acyls-ACPs in the fatty acid synthetic pathway (Dehesh, K. et al., 1996, The Plant Journal 9(2): 167-172). 
     The second reaction is catalysed by an acyl-CoA synthetase. In one embodiment of the invention, the enzyme was isolated from  Pseudomonas oleovorans , a bacteria which accumulates PHAs mcl  (medium-chain length polyhydroxy alkanoates). The enzyme is encoded by gene K of operon alkBFGHJKL which is responsible for alkanoate synthesis. This acyl-CoA synthetase (GenBank accession # X65936) is specific to medium-chain length fatty acids (van Beilen, J. B. et al. (1992) DNA sequence determination and functional characterization of the OCT-plasmid-encoded alkJKL genes of  Pseudomonas oleovorans . Molecular Microbiology 6(21): 3121-3136). 
     The third reaction is catalysed by a keto thiolase. This reaction is a condensation reaction which will add one acetyl-CoA moiety to the acyl-CoA, thus releasing one CoA molecule. This condensation reaction is reversible, and creates a 3-keto acyl CoA with two extra carbon. The products following this reaction will be therefore C10- and C12-3-OH-acyl CoAs and free CoA. The enzyme described in one example of the present invention has been isolated from Brassica napus, in which it is part of the oxidation pathway (Olesen, C. J. et al. (1997) The glyoxysomal 3-ketoacyl-CoA thiolase precursor from  Brassica napus  has enzymatic activity when synthesized in  E. coli  (FEBS Letters 6(21): 138-140; GenBank accession # X93015). 
     The fourth reaction, according to the present invention, is catalysed by a yeast 3-hydroxyacyl-CoA dehydrogenase which produces R-(−)-3-OH-acyl-CoAs (Hiltunen, J. K. et al. (1992) Peroxisomal multi functional β-oxidation protein of  Saccharomyces cerevisiae . J. Biol. Chem. 267:6646-6653; GenBank accession # M86456). Homologs of this 3-keto-acyl-CoA dehydrogenases usually produce S-(−)-3-OH-acyl-CoAs in the β-oxidation pathway. The 3-hydroxyacyl-CoA dehydrogenase domain of the multi functional protein (MFP) of yeasts exhibits this unique catalytic property. Thus the product of this reaction will be R-(−)-3-OH-decanoyl-CoA and R-(−)-3-OH-dodecanoyl-CoA. Both molecules can serve as substrate for the polymerization reaction catalyzed by PHA synthases. 
     The last reaction of this embodiment is catalysed by a PHA synthase from  Pseudomonas aeruginosa , which accumulates large amounts of PHA granules in nutrient stress conditions (Timm, A. and Steinbüchel, A., 1992) Cloning and molecular analysis of the poly(3-hydroxyalkanoic acid) gene locus of  Pseudomonas aeruginosa  PAO1. Eur. J. Appl. Microbiol. 209: 15-30; GenBank accession # X66592). Analysis of depolymerization products shows that this enzyme uses R-(−)-3-OH-acyl-CoAs of C6 to C14 in length as substrates, with an apparent preference for C10 and C12 R-(−)-3-OH-acyl-CoAs. 
     In one embodiment of the present invention, each of these genes is sub-cloned in an appropriate expression vector. In one embodiment of this invention the host is a plant cell and any know plant expression vector can be used according to the present invention. Said plant expression vector can contain a promoter sequence, a 5′UTR sequence, a chloroplast transit peptide sequence, the complete coding sequence of the gene, a stop codon, an a 3′UTR region containing a eukaryotic polyadenylation signal and a polyadenylation site. The polyadenylation signal is usually characterized by effecting the addition of polyadenylic acid tracks to the 3′ end of the mRNA precursor. Polyadenylation signals are commonly recognized by the presence of homology to the canonical form 5′ AATAAA-3′ although variations are not uncommon. 
     Examples of suitable 3′ regions are the 3′ transcribed non-translated regions containing a polyadenylation signal of Agrobacterium tumor inducing (Ti) plasmid genes, such as the nopaline synthase (Nos gene) and plant genes such as the soybean storage protein genes and the small subunit of the ribulose-1, 5-bisphosphate carboxylase (ssRUBISCO) gene. The 3′ untranslated region from the structural gene of the present construct can therefore be used to construct chimeric genes for expression in plants. 
     The chimeric gene construct of the present invention can also include further enhancers, either translation or transcription enhancers, as may be required. These enhancer regions are well known to persons skilled in the art, and can include the ATG initiation codon and adjacent sequences. The initiation codon must be in phase with the reading frame of the coding sequence to ensure translation of the entire sequence. The translation control signals and initiation codons can be from a variety of origins, both natural and synthetic. Translational initiation regions may be provided from the source of the transcriptional initiation region, or from the structural gene. The sequence can also be derived from the promoter selected to express the gene, and can be specifically modified so as to increase translation of the mRNA. 
     To aid in identification of transformed plant cells, the constructs of this invention may be further manipulated to include plant selectable markers. Useful selectable markers include enzymes which provide for resistance to an antibiotic such as gentamycin, hygromycin, kanamycin, and the like. Similarly, enzymes providing for production of a compound identifiable by colour change such as GUS (β-glucuronidase), or luminescence, such as luciferase are useful. 
     This invention is directed at any means by which the genes of interest can be transfected in a plant providing it results in stable integration and expression. Preferred means are, Agrobacterium mediated DNA transfer which requires T-DNA borders, and selectable markers; DNA bombardment, which requires selectable markers, and electroporation which can in some cases be used without screenable markers. These various cloning and plant transformation methods are well know in the art. For reviews of such techniques see for example Weissbach and Weissbach,  Methods for Plant Molecular Biology , Academy Press, New York VIII, pp. 421-463 (1988); and Geierson and Corey, Plant  Molecular Biology,  2d Ed. (1988). 
     Also considered part of this invention are transgenic organisms containing the chimeric gene construct of the present invention. In one embodiment of this invention the transgenic organism is a plant. Methods of regenerating whole plants from plant cells are known in the art, and the method of obtaining transformed and regenerated plants is not critical to this invention. In general, transformed plant cells are cultured in an appropriate medium, which may contain selective agents such as antibiotics, where selectable markers are used to facilitate identification of transformed plant cells. Once callus forms, shoot formation can be encouraged by employing the appropriate plant hormones in accordance with known methods and the shoots transferred to rooting medium for regeneration of plants. The plants may then be used to establish repetitive generations, either from seeds or using vegetative propagation techniques. 
     When specific sequences are referred to in the present invention, it is understood that these sequences include within their scope sequences that are “substantially similar” to said specific sequences. Sequences are “substantially similar” when at least about 80%, preferably at least about 90% and most preferably at least about 95% of the nucleotides match over a defined length of the molecule. Sequences that are “substantially similar” include any substitution, deletion, or addition within the sequence. DNA sequences that are substantially similar can be identified in Southern hybridization experiments, for example under stringent hybridization conditions (see Maniatis et al., in Molecular Cloning (A Laboratory Manual), Cold Spring Harbor Laboratory (1982) p 387 to 389). 
     The specific sequences, referred to in the present invention, also include sequences which are “functionally equivalent” to said specific sequences. In the present invention functionally equivalent sequences refer to sequences which although not identical to the specific sequences provide the same or substantially the same function. DNA sequences that are functionally equivalent include any substitution, deletion or addition within the sequence. 
     Since the creation of the novel metabolic pathway requires the simultaneous expression of 5 different transgenes, 5 independent transformants can be produced, and genotypes containing the 5 transgenes are produced by repeated crossing of mono-transgenics and selection. Alternately, series of genes can be co-transfected on single constructs, thus reducing the need for extensive crossing. Other means of integrating the novel genes in chloroplasts also include the direct transfection of DNA on chloroplastic DNA by recombination using homologous or heterologous border sequences. Using this methodology, polycistronic constructs (multiple gene construct under the control of a single promoter) could be used to bring the 5 modifications. These methods are well known to persons of skill in the art. 
     While this invention is described in detail with particular reference to preferred embodiments thereof, said embodiments are offered to illustrate but not limit the invention, as shown in the following example. 
     EXAMPLES 
     PHA synthase 
     Cloning of the PHA synthase gene PhaC1 (X66592, Timm, 1992) was performed by PCR amplification of genomic DNA from  Pseudomonas aeruginosa  strain PAO1 with the “Expand” system from Boehringer Mannheim. Template DNA was extracted and purified. The primer at the 5′ terminus was 5′GATC  GCATGC   GAAGGATTTC  T ATG AGTCAG3′ (SEQ ID NO:4); it contains the SphI and XmnI restriction sites upstream from the ATG. The primer at the 3′terminus was 5′GATC  GAATTCTCA TCGTTCATGCACGTAGG3′ (SEQ ID NO:5); a EcoRI site had been introduced downstream of the stop codon. Conditions for the PCR were: 94° C.-2′

     The PCR products formed were separated on agarose gels and the band corresponding to the expected size was removed from the gel. Purified DNA was then digested with SphI/EcoRI, and the 1692 pb fragments were cloned in pUC1 8. Complete homology of the selected clone was verified by sequencing. The synthase gene was then cloned at the SphI/EcoRI sites of pGEM-7Zf (Promega) containing the 3′non coding region (3′nc) of SSU-rubisco gene RbcsK (Khoudi et al 1997) previously cloned at the EcoRI/SmaI site. The SphI/SacI fragment (2138 pb) containing PhaC1+3′nc was then sub-cloned into Litmus28 (NE Biolabs) containing the complete 5′ region of RbcsK with the promoter and transit peptide (5′ RbcsK), previously cloned at the SalI/SphI site. Finally, a fragment of 4112 bp containing the 5′RbcsK+PhaC1+3′nc was cloned into the SalI/SacI site of pBI 101.2 (Clontech), removing then the GUS gene. This construct was then transfected to  Agrobacterium tumefaciens  strain LBA4404, and incorporated in the genome of selected plant cells cells through co-cultivation with transgenic  A. tumefaciens , as described by Desgagnés et al (1995) Plants were regenerated from transgenic cells, and leaf tissue is used for the selection of the best transgenic lines by Northern analysis. PHA synthase activity of the selected lines was then measured in clarified leaf extracts as described in the prior art. 
     Hydroxyacyl-CoA Dehydrogenase 
     The domain of the multi functional b-oxidation protein (MFP) (M86456) (Hiltunen, 1992) which encodes for R-3-hydroxyacyl-CoA dehydrogenase was amplified by PCR from  Saccharomyces cerevisiae . It has been shown that the protein contains two activities: a 2-enoyl-CoA hydratase 2, converting trans-2-enoyl-CoA to R-3-hydroxyacyl-CoA, and a R-3-hydroxyacyl-CoA dehydrogenase, converting R-3-hydroxyacyl-CoA to 3-ketoacyl-CoA. A truncated version of MFP lacking 271 carboxyl-terminal amino acids was also overexpressed and purified and it was shown that it has only the R-3-hydroxyacyl-CoA dehydrogenase activity. These results clearly demonstrate that the b-oxidation of fatty acids in the yeast follows a previously unknown stereochemical course, namely it occurs via a R-3-hydroxyacyl- CoA intermediates. 
     The expression of the truncated version in chloroplasts of plants with a medium-chain length- specific thioesterase, an acyl-CoA synthetase and a thiolase will allow the production of R-3-hydrozyacyl-CoAs, the substrate of the PHA synthase. 
     Template genomic DNA was extracted and purified from  S. cerevisiae  as described in Current Protocols in Molecular Biology, 1997, section 13.11.1-13.11.4. The 5′ primer used contains the SphI site upstream of the ATG (GATC GCATGC TA ATG CCTGGAAATTTATCCTTC) (SEQ ID NO:6) and the 3′ primer has an ApaI site downstream a newly introduced stop codon (GATC GGGCCCTTA CGGGTTGATAGTGTTGCGACT) (SEQ ID NO:7). The PCR conditions are described above, except that the annealing temperature used was 50° C. The PCR fragment was purified, digested SphI/ApaI and the 1799 bp fragment was cloned in pKitmus/RbscK-3′nc. This vector is a pLitmus28 derivative that contains a cassette for chloroplasts expression. This cassette has in 5′ the promoter of the small subunit of the ribulose 1,5-biphosphate carboxylase (rubisco) of alfalfa, its 5′ non-translated region and the targeting signal to chloroplasts, followed by a multiple cloning site (MCS), and in 3′, the 3′ non coding region of rubisco (Khoudi, et al., 1997). The region in 5′ is a 1978 bp SalI/SphI fragment that has at its 3′ end the sequence that codes for the 58 amino acids of the transit peptide, followed by the ATG of the mature protein. This ATG is found to be the one in the SphI site. The dehydrogenase clone in the MCS is then in frame with the targeting signal, having a leucine in between the ATG of the mature rubisco protein and the one of the gene. 
     The 3′ non coding region is a 441 bp EcoRI/SmaI fragment that has the two PolyA signals of the small subunit of rubisco. 
     A potential clone has been sequenced with these primers: 
     Jonc. Rub. 5′ AAGTCCATGGCTGGCTTCCCA (SEQ ID NO:8) 
     Junc. Rub 1023r 5′ AGATAGTAAATTCTCAAATGAATTC (SEQ ID NO:9) 
     DHSc125c 5′ TTGACAGGTGGCTATAAG (SEQ ID NO:10) 
     DHSc498r 5′ CGTTTCTGCATGAGGAGC (SEQ ID NO: 11) 
     And a wild type clone, pKitmus/RbscK-DH-3′nc #9, has been conserved for further manipulations (FIGS.  5 A- 5 C). 
     The gene was put in a cassette for transient expression. Plasmid 35SC4PPDK-sGFP-TYG-nos was obtained from Jen Sheen at the Department of Molecular Biology at Massachusetts General Hospital and contains the following: the 35S-C4PPDK promoter flanked by XhoI and BamHI sites; a gene encoding GFP flanked by BamHI and PstI sites that contains an amino acid change at position 65 for increased fluorescence and whose codon usage is optimized for plant expression; and a polyadenylation sequence flanked by PstI and EcoRI sites. The BamHI site after the promoter was changed for a SphI site by a treatment of the vector digested BamHI with the Klenow and its ligation with a SphI linker. The vector produced was then digested EcoRI, treated with the Klenow and digested SphI to yield a SphI/blunt vector fragment of 3290 bp that has lost the gene GFP and the NOS. pKitmus/RbscK-DH-3′nc was digested SphI-SmaI and the 2198 bp fragment containing the dehydrogenase and the 3 ′non coding region of alfalfa rubisco was ligated in the vector to produce pUC/35S.C4PPDK.DH.3′nc, a 5488 bp clone used in the transient expression experiment (FIGS.  5 D- 5 E). 
     For plant expression, the cassette containing the alfalfa rubisco promoter, the dehydrogenase and the 3′ non coding region of alfalfa rubisco was obtained by a SalI/SmaI digestion of pKitmus/RbscK-DH-3′nc #9 and cloned in pCambia 2300. The clone formed is called pCambia/RbscK-DH-3′nc (FIGS.  5 F- 5 J). 
     Diagrams of the constructs are shown in FIG. 4, and the sequences files are found in FIGS. 5A-5J. 
     For the enzymatic activity of the (D)-3-hydroxyacyl-CoA dehydrogenase in  E. coli , a 2XYT.Ap liquid culture (5 mL) is innoculated with a single colony of DH5α: pTRCN/FOX2 and the culture is placed under agitation at 30° C. for 16 hours. This overnight culture is used to innoculate (1%) 50 mL of 2XYT.Ap media. The cultures are put at 30° C. under agitation until the OD600 nm reach 0.6. IPTG (0.4 mM) is added and the culture is incubated for another 4 hours. The cells are collected by centrifugation (15 min./5000 g/4° C.) and stored at −80° C. The cells are resuspended in 20 mM KH 2 PO 4  buffer (pH 7.0), 0.5 mM DTT, 0.1 mM PMSF and are disrupted by sonication with pulses of 0.2 sec for a total period of 20 sec. The cells are returned to ice for cooling purposes and the sonication procedure is repeated two more times to ensure lysis. The extract is clarified by centrifugation in a microfuge (12000 g/15 min./4° C.) prior to activity measurements. 
     The dehydrogenase reaction measured the oxidation of a 3-hydroxyacyl-CoA in a 3-ketoacyl-CoA and is followed by monitoring the formation of the Mg 2+  complex of 3-ketoacyl-CoA at 303 nm. The incubation mixture consisted of 50 μmol Tris-Ci (pH 9.0), 50 μg bovine serum albumin, 50 μmol KCl, 1 μmol NAD + , 25 μmol MgCl 2 , 1 μmol pyruvate and 10 μg lactate dehydrogenase in a total volume of 1 mL. The lactate dehydrogenase allows the regeneration of NAD +  using the pyruvate as substrate. The reaction is monitored at room temperature with all the components of the incubation mixture and then 10 μg of L-3-hydroxyacyl-CoA dehydrogenase is added. After about 1 minute, 50 nmol of the substrate DL-3-hydroxyoctanoyl-CoA is added. When the OD 303nm  is stabilized, meaning that the L-3-hydroxyoctanoyl-CoA is completely oxidized, then the extract (1%) is added. The reaction is monitored for another 5 minutes. 
     The R-3-hydroxyacyl-CoA dehydrogenase activity was measured in DH5α overexpression the MFP Fox2 gene of  Saccharomyces cerevisiae . The extinction coefficient used for the 3-ketooctanoyl-CoA is 14.5×10 3  cm −1  M −1 . The monitoring activity is shown on FIG.  6 A and the linear part of the graph that represents the R-3-hydroxyacyl-CoA dehydrogenase activity is shown in FIG.  6 B. The specific activity is 0.81 Units/mg protein. 
     Transient expression of the 3-hydroxyacyl-CoA dehydrogenase in plant cells was done by transformation of  Arabidopsis thaliana  protoplasts with pUC/35S.C4PPDK.DH.3′nc (Sheen, J., et al., 1995). For the enzymatic activity of the (D)-3-hydroxyacyl-CoA dehydrogenase in plant cells,  Arabidopsis thaliana  protoplasts are harvested by centrifugation (115 g) and the supernatant is removed. An aliquot (14 μL) of 7×stock of protease inhibitor stock is added to the sample and the sample is brought to a final volume of 100 μL with a solution containing 20 mM KH 2 PO 4  buffer (pH 7.0), 0.5 mM DTT, 0.1 mM PMSF. The  7×stock of protease inhibitors is prepared by dissolving one “Complete Mini Protease Inhibitor Tablet” (Boehringer Manneheim) in  1.5 mL 20 mM KH 2 PO 4  buffer (pH 7.0), 0.5 mM DTT, 0.1 mM PMSF. The protoplasts are disrupted in a 1.5 mL centrifuge tube using a pellet pestle mixer (Kontes) for 30 seconds. Soluble proteins are separated from insoluble proteins by centrifugation at maximum speed in a microcentrifuge (10 min, 4° C.). Dehydrogenase activity was measured as described above. The R-3-hydroxyacyl-CoA dehydrogenase activity was measured in protoplasts of  Arabidopsis thaliana  transformed with pUC/35S.C4PPDK.DH.3′nc. The extinction coefficient used for the 3-ketooctanoyl-CoA is 14.5×10 3  cm −1  M −1 . 
       Arabidopsis thaliana  plants were transformed with pCambia/RbscK-DH-3′nc following a floral dip protocol (Clough, S. J., et al. 1998) and using the  Agrobacterium tumefasciens  strain GV3101/pMP90 (Koncz, C., et al., 1986). For the enzymatic activity of the (D)-3-hydroxyacyl-CoA dehydrogenase in plants, leaves of  Arabidopsis thaliana  expressing the enzyme are collected and grinded in 5 volumes of extraction buffer containing 50 mM Tris-Cl buffer (pH 8.0), 0.4% β-mercaptoethanol, 2 mM PMSF. The extract is clarified on Miracloth and centrifuged (12 000g/15 min./4° C.). The supernatant is desalted on a Sephadex G-25 PD-10 column (Pharmacia) eluting in a buffer containing 20 mM KH 2 PO 4  buffer (pH 7.0), 0.5 mM DTT, 0.1 mM PMSF. Dehydrogenase activity was determined as described above. The R-3-hydroxyacyl-CoA dehydrogenase activity was measured in plants of  Arabidopsis thaliana  transformed with pCambia/RbscK-DH-3′nc. The extinction coefficient used for the 3-ketooctanoyl-CoA is 14.5×10 3  cm −1  M −1 . 
     Keto-acyl CoA thiolase 
     Cloning of the thiolase gene (X93015) (Olesen, 1997) was performed by PCR amplification of genomic DNA from  Brassica napus  as described above, except that the annealing temperature used was 50° C. Template DNA was prepared from  B. napus  leaves as described by Rogers &amp; Bendich, Plant Mol. Biol., 1988, A6:1-10. The primer at the 5′ end was 5′GATC GCATGC TAGCTGGGGACAGTGCTGCGTATC-3′ (SEQ ID NO:12) with an added SphI site, and at the 3′ end 5′-GATC GAATTCCTA ACGAGCGTCCTTGGACAAAAG-3′ (SEQ ID NO:13) with an EcoRI site downstream of the stop codon. Primers were selected so that amplification would be initiated at position 106 of the cDNA and therefore eliminate the N-terminal targeting signal for glyoxysomes. The gel-purified PCR products were digested with SphI/EcoRI and cloned in a derivative of pLitmus 28 modified as described above for cloning of yeast dehydrogenase. Suitable clones are fully sequenced. Sequence was compared with the published cDNA (1389 pb), although amplicons were produced from genomic DNA template. Homologous amplicons with introns and without the targeting signal are 2568-bp in size. The whole construct with the homologous gene was sub-cloned at the SalI/SmaI site in pBI 101.2. Transformation of  A. tumefaciens , transformation of selected plants, and regeneration of transgenic lines was performed as described above. Selection of best transgenic lines was performed with Northern hybridization. 
     Acyl-ACP Thioesterase 
     A gene encoding for a thioesterase with specificity for 8:0 and 10:0-ACP substrates (U39834) (Dehesh, 1996) was amplified by PCR from  Cuphea hookeriana  as described above, except that the annealing temperature used was 60° C. Template genomic DNA was prepared with the Qiagen Genomic Tip Protocol as described by the manufacturer. The primer at the 5′ end was 5′-GATC TCTAGAATG GTGGCTGCTGCAGCAAGTTCCG-3′ (SEQ ID NO:14) with a XbaI site upstream of the ATG; the primer at the 3′ end was 5′-GATC GGGCCCCTA AGAGACCGAGTTTCCATTTGAAG-3′ (SEQ ID NO:15) with an ApaI site downstream of the stop codon. The PCR product was cloned at the XbaI/ApaI site in the plant vector pCambia 2300, modified to harbor the RbscK promotor (SalI/SphI) with the transit peptide, a multiple cloning site between SphI and EcoRI and the 3′ non coding region of RbscK (EcoRI/SmaI). Transformation of  A. tumefaciens , transformation of selected plants, and regeneration of transgenic lines was performed as described above. Selection of best transgenic lines was performed with Northern hybridization. 
     Acyl-CoA Synthetase 
     Cloning of the acyl-CoA synthetase gene (X65936) (van Beilen, 1992) was performed by PCR amplification of genomic DNA from  Pseudomonas oleovorans . Template DNA was prepared as described in Current Protocols in Molecular Biology, 1997, 2.4.1-2.4.2. The primer at the 5′-end was GATC GGATCCATG TTAGGTCAGATGATGCGT-3′ (SEQ ID NO:16) with a BamHI site upstream of the ATG; the primer at the 3′ end was 5′-GATC GAATTCTTA TTCACAGACAGAAGAACT-3′ (SEQ ID NO:17) with an EcoRI site downstream of the stop codon. The PCR product was cloned in the BamHI/EcoRI site of pLitmus 28 modified as described above for cloning of yeast dehydrogenase. Suitable clones were fully sequenced. Wjole constructs were then sub-cloned into pBI.101.2. Transformation of  A. tumefaciens , transformation of alfalfa and tobacco plants, and regeneration of transgenic lines was performed as described above. Selection of best transgenic lines was performed with Northern hybridization.
