     BACKGROUND OF THE INVENTION 
     Gamma-linolenic acid (GLA) is an essential fatty acid in the omega-6 family that is found primarily in plant-based oils. GLA is synthesized from linoleic acid (LA) via the action of the enzyme delta-six desaturase (Δ6-desaturase). The beneficial effects of GLA derive from the fact that GLA serves as the precursor to a number of other essential fatty acids such as arachidonic acid, which is a precursor of prostaglandins and other physiologically important molecules. 
     Unsaturated fatty acids such as linoleic (C 18 Δ 9, 12) and α-linolenic (C 18 Δ 9, 12, 15) acids are essential dietary constituents that cannot be synthesized by vertebrates because while vertebrate cells can introduce double bonds at the Δ 9 position of fatty acids, they cannot introduce additional double bonds between the Δ 9 double bond and the methyl-terminus of the fatty acid chain. Because they are required to synthesize other products, linoleic and α-linolenic acids are essential fatty acids, which are usually obtained from plant sources. LA can be converted by mammals into GLA (C 18 Δ 6, 9, 12) which can in turn be converted to arachidonic acid (20:4), a critically important fatty acid since it is an essential precursor of most prostaglandins. 
     The dietary provision of LA, by virtue of its enzymatic conversion to GLA and then into arachidonic acid, could satisfy the dietary need for GLA and arachidonic acid. However, the consumption of fats that are less highly unsaturated, such as LA, has been correlated with health risks such as hypercholesterolemia, atherosclerosis and other clinical disorders which increase susceptibility to coronary disease. In contrast, the consumption of fats that are more highly unsaturated has been associated with decreased blood cholesterol concentration and reduced risk of atherosclerosis. Consumption of the unsaturated fatty acid GLA has been shown to be particularly beneficial. Thus, the consumption of the more unsaturated GLA would be preferred over the consumption of LA. It would thus be desirable to generate additional sources rich in GLA for human consumption. 
     GLA acts as a precursor for the formation of eicosanoids including prostaglandins. Prostaglandins are vital hormone-like compounds that strengthen cell membranes and serve as cellular signaling molecules. Beneficial effects of GLA have been observed in humans and animals. GLA may help to regulate blood pressure, reduce inflammation and improve immune function. GLA supplementation may benefit a wide range of diseases and conditions including lupus, cancer, allergies, arthritis and ulcerative colitis. GLA may improve the efficacy of drugs used to treat cancer. GLA may help to reduce the symptoms of premenstrual syndrome and menopause; to improve skin health and to treat eczema, acne, rosacea, psoriasis and dandruff; to improve psychiatric and neurological disorders including Alzheimer&#39;s disease, Huntington&#39;s chorea, multiple sclerosis, attention deficit hyperactivity disorder, depression and Raynaud&#39;s phenomenon; to block diabetic neuropathy; to treat cirrhosis of the liver; to improve dry-eye conditions such as Sjögren&#39;s syndrome; and to treat cardiovascular disease, osteoporosis, hyperlipidemia and other symptoms associated with aging. Furthermore, GLA has been implicated as a stimulator for the body to burn brown fat. Brown fat is the inner body fat that surrounds vital organs and acts as a fat-burning factory, using calories for heat rather than storing them as white fat. The burning of brown fat is important for the maintenance of ideal body weight. Increased GLA consumption may thus help to stimulate the process of brown fat metabolism. 
     Existing GLA supplements are typically derived from plant sources that are naturally higher in GLA such as evening primrose oil, black currant oil and borage oil. However, GLA represents a relatively small fraction of the total fatty acids in these natural sources. Only approximately 7-10% (evening primrose), 14-19% (black currant oil) and 20-26% (borage oil) of the fatty acids from these sources are available as GLA. Despite GLA&#39;s broad health benefits, its use is currently limited by the high cost and low concentrations of existing GLA supplements. An average adult would need to consume 10 or more capsules of existing GLA supplements to receive its optimal health benefits. It would be useful to have a less expensive, readily available source of oil that was higher in GLA than the naturally occurring specialty oils currently used for GLA supplements. Such a source would allow consumers to receive the optimal health benefits of GLA, while spending less money on supplements and ingesting significantly less total oil and fewer calories. 
     Safflower is a commercially important agricultural crop. Safflower was first cultivated in the Near East thousands of years ago as a source of dye and other products that could be derived from the plant. Safflower in this century has been utilized as a source of edible oils. Safflower was first introduced to agriculture in the United States in the 1930s as a source of edible oils. Since then, varieties with improved oil content have been developed. Safflower oil primarily comprises the fatty acids palmitic, stearic, oleic and LA. Palmitic (C16:0) and stearic acids (C18:0) are saturated fatty acids; oleic (C18:1) and linoleic (C18:2) are unsaturated fatty acids. However, safflower plants naturally produce only negligible amounts of GLA. 
     As such, transgenic safflower plants with seeds containing higher levels of GLA than occur naturally would have great utility.

     DETAILED DESCRIPTION OF THE INVENTION 
     In order to ensure a complete understanding of the invention, the following non-limiting definitions are provided. 
     Δ6-desaturase is an enzyme that introduces a double bond between carbons 6 and 7 from the carboxyl end of a fatty acid molecule. 
     Δ12-desaturase is an enzyme that introduces a double bond between carbons 12 and 13 from the carboxyl end of a fatty acid molecule. 
     As used herein, the abbreviation “GLA” is used to refer to gamma-linolenic acid. 
     Percentage by weight is meant to indicate the content of a particular fatty acid in a seed and/or oil from the seed based on weight. Thus, the percentage by weight of GLA or “by weight GLA” is calculated based on the weight of GLA divided by weight of total fatty acids multiplied by 100%. For example, “GLA levels at 5% by weight” or “5% by weight GLA” refers to seeds or oil from seeds that contains 5 grams of GLA and 100 grams of total fatty acid. 
     Introduction 
     As shown in  FIG. 1 , GLA is produced in a biochemical pathway wherein OA is converted to LA. LA in turn is converted into GLA through the action of fatty acid desaturases, enzymes that introduce double bonds at specific locations in the fatty acid carbon chain. When these enzymes are transferred into cells that produce OA or LA, GLA is produced. 
     Safflower is a commercially important crop plant and is a valuable source of vegetable oil. Because safflower plants do not naturally produce GLA in any significant quantity, it would not be an obvious candidate for the production of this fatty acid. For example, because safflower plants do not normally produce GLA, one might expect that the expression of high levels of this non-endogenous fatty acid might be detrimental to the plant because the exogenously introduced GLA would interfere with the function of endogenous fatty acids. It has been surprisingly found that GLA can be expressed in safflower seeds and that this expression occurs at unexpectedly high levels, even when compared with other plants that express transgenes that are free of the concerns discussed above. 
     Characteristics of Desaturase Enzymes 
     The reaction catalyzed by desaturases is:
 
R 1 —CH 2 —CH 2 —R 2 +O 2 +2 e   − +2H + →R 1 —CH═CH—R 2 +2 H 2 O.
 
     Many fatty acid desaturases are membrane bound metalloenzymes. Most are believed to contain two iron atoms at their active site. As shown in  FIGS. 2 ,  3 ,  5  and  6 , the Δ6- and Δ12-desaturases share a degree of sequence identity and similarity within each respective class of enzymes. As shown in  FIGS. 4 and 7  among the regions of conservation within the desaturase family are three strongly conserved histidine-rich sequences (His-boxes) with the general motifs HXXXH, HXXHH and HXXHH or QXXHH. These boxes are required for enzyme activity and are separated by membrane-spanning domains that are required for their correct orientation in the active site. Many enzymes including the Δ5- and Δ6-desaturases contain a cytochrome b5-like N-terminal extension. This is often accompanied by a change in the sequence of the third His box to QXXHH. Electrons acquired from NADH cytochrome b5 reductase are transferred to cytochrome b5 or the cytochrome b5 domain of the desaturase and then to the active site of the desaturase. The mixed oxidation/reduction reaction proceeds through two iron atoms that are stabilized by interaction with the conserved histidine boxes. As discussed below, these structural features and, in particular, the conserved residues that make up the metal binding site, are conserved across species and are responsible for the enzymatic function of this class of enzymes. 
     Sources of Desaturase Enzymes 
     For the production of GLA, one or more desaturase enzymes will be required depending upon the host cell and the availability of substrates. For instance, in a plant that naturally has abundant amounts of LA, Δ6-desaturase is required to catalyze the conversion of LA into GLA. In plants that naturally have abundant amounts of OA, but not LA, a combination of Δ12- and Δ6-desaturase enzymes are required to generate GLA. 
     Considerations for choosing a specific desaturase polypeptide to use include correct localization and functioning of the polypeptide in the microsomal/endoplasmic reticulum compartment of the cell (these enzymes are membrane bound and must function in conjunction with the existing triglyceride biosynthetic machinery of the cell), whether the polypeptide is a rate limiting enzyme or a component thereof, whether the desaturase used is essential for synthesis of a desired poly-unsaturated fatty acid and/or co-factors required by the polypeptide. The expressed polypeptide preferably has parameters compatible with the biochemical environment of its location in the host cell. For example, the polypeptide may have to compete for substrate with other enzymes in the host cell. Analyses of the K m  and specific activity of the polypeptide in question therefore are considered in determining the suitability of a given polypeptide for modifying GLA production in a given host cell. The polypeptide used in a particular situation therefore is one which can function under the conditions present in the intended host cell but otherwise can be any polypeptide having desaturase activity that has the desired characteristic of being capable of modifying the relative production of GLA. 
     A number of Δ6- and Δ12-desaturases are known including those described in U.S. Pat. No. 6,635,451, WO02/081668, U.S. Pat. No. 6,635,451, U.S. Patent App. No. 2003/0167525, U.S. Pat. Nos. 6,459,018, 5,972,644, 6,432,684, 5,968,809, 5,972,664, 6,051,754, 6,075,183, 6,136,574, 5,552,306, 5,614,393, 5,663,068, 5,689,050, 5,789,220, 6,355,861 and 6,492,108, which are hereby incorporated by reference in their entirety and for the specific sequences disclosed therein. Among the sources of Δ6- and Δ12-desaturases useful for the practice of this invention are those from plants and fungi. For example, Δ6- and Δ12-desaturases from the genera  Mucor, Saprolegnia diclina, Mortierella, Mortierella alpina, Conidiobolus, Pythium, Phytophthora, Penicillium, Porphyridium, Coidosporium, Mucor circinelloides, Fusarium, Aspergillus, Candida, Euphorbia, Dimorphoteca, Rhodotorula, Entomophthora, Thraustochytrium, Saprolegnia, Borago and Primula  are useful in practice of this invention. Desaturases from sunflower, canola, rice, moss, and  C. elegans  can also be used in the practice of this invention. Such sequences will include histidine-rich boxes. These sequences can be used as well as sequences that have at least 80%, 85%, 90% or 95% identity based on various alignment methods well known in the art. Also useful are sequences that hybridize to the above sequences under high to moderate stringency. Hybridization and washing conditions that allow identification of additional sequences that correspond to desaturase sequences are also well known in the art, some of which are described below. 
     Among the methods for sequence alignment that are well known in the art are the programs and alignment algorithms described in: Smith and Waterman, J Mol Biol 147:195, 1981; Needleman and Wunsch, J Mol Biol 48:443, 1970; Pearson and Lipman, PNAS 85:2444, 1988; Higgins and Sharp, Gene 73:237, 1988; Higgins and Sharp, Comput Appl Biosci 5:151, 1989; Corpet, Nucl Acids Res 16:10881, 1988; Huang, Genomics 14:18, 1992; and Pearson, Methods Mol Biol 24:307, 1994. Altschul et al., (Nature Genetics 6:119, 1994) present a detailed consideration of sequence alignment methods and homology calculations. 
     The NCBI Basic Local Alignment Search Tool (BLAST) (Altschul et al., J Mol Biol 215:403, 1990) is available from several sources, including the National Center for Biotechnology Information (NCBI, Bethesda, Md.) and on the Internet, for use in connection with the sequence analysis programs blastp, blastn, blastx, tblastn and tblastx. It can be accessed at the NCBI Website. A description of how to determine sequence identity using this program is available at the NCBI website. 
     The AlignX program from Vector NTI was used to generate  FIGS. 2 ,  3 ,  5  and  6 .  FIG. 2  shows an alignment of Δ6-desaturases from a number of different plant species.  FIG. 3  shows an alignment of desaturases from a number of fungal species.  FIGS. 5 and 6  show alignments of Δ12-desaturases from a number of plant and fungal species, respectively. These figures show the structural and functional relatedness of different Δ6- and Δ12-desaturases within their respective classes of enzymes. Any of the Δ6- or Δ12-desaturases shown in these figures can be used to practice the current invention as well as others that can be identified using the methods of this invention or otherwise available in the art as corresponding to Δ6- or Δ12-desaturases. Also encompassed by this invention are modifications of desaturases that still retain activity or possessed enhanced enzymatic activity that can be obtained through random or site directed mutagenesis. 
     It is well known to the skilled artisan that any of the sequences disclosed herein, as well as others known in the art, and previously unknown desaturases can be isolated using conventional cloning methods such as nucleic acid hybridization or PCR for use in the present invention. 
     Examples of hybridization conditions that can be used to isolate desaturase sequences include the following. Stringent conditions are sequence dependent and vary according to the experimental parameters used. Generally, stringent conditions are selected to be about 5° C. to 20° C. lower than the thermal melting point (T m ) for the specific sequence at a defined ionic strength and pH. The T m  is the temperature (under defined ionic strength and pH) at which 50% of the target sequence hybridizes to a perfectly matched probe. Conditions for nucleic acid hybridization and calculation of stringencies can be found in Sambrook et al. (Molecular Cloning—A Laboratory Manual 2 nd  Edition, Cold Spring Harbor Laboratory Press, New York, 1989) and Tijssen (Hybridization with Nucleic Acid Probes, Elsevier Science Ltd., Amsterdam, 1993). Examples of factors that affect nucleic acid hybridization include: temperature, salt conditions, the presence of organic solvents in the hybridization mixtures, the lengths and base compositions of the sequences to be hybridized and the extent of base mismatching. An example of high stringency conditions for hybridizing a probe to a filter-bound DNA is 5×SSC, 2% sodium dodecyl sulfate (SDS), 100 μg/ml single stranded DNA at 55-65° C. for 20 minutes and washing in 0.1×SSC with 0.1% SDS at 60-65° C. for 20 minutes. 
     Alternatively, PCR primers can be designed to amplify particular desaturases of interest if the sequence of the desaturase cDNA is known. Further, PCR primers can be designed to conserved regions of the desaturases to isolate additional family members. Protocols for performing PCR reactions are well known in the art and are described in manuals such as PCR Protocols: A Guide to Methods and Applications by M. Innes et al., Academic Press, 1989. 
     Once sequences have been identified via sequence identity, hybridization, identification of conserved histidine boxes, or other suitable methods, desaturase activity can be tested using several different assays. By way of example is the use of yeast as described in U.S. Pat. No. 5,968,809 in Examples 5 to 7 and Knutzon, et al. J. Biol. Chem. 273 (45): 29360-29366 (1998), both which are hereby incorporated by reference. The yeast may be  Sacharomyces cerevisiae  or an oleaginous species. The sequence of interest is cloned into a yeast expression vector and transformed into yeast. The recombinant yeast strains are grown in media containing various substrates and the fatty acid content of the lipid fraction is analyzed to evaluate desaturase activity. Δ6-desaturase activity can be monitored by using linoleic acid as a substrate and detecting gamma-linolenic acid. Δ12-desaturase activity can be monitored by detecting conversion of endogenous oleic acid to linolenic acid. 
     Desaturase activity can also be tested using  Arabidopsis . Sequences of interest are cloned into appropriate vectors, transformed into  Arabidopsis , and activity detected by evaluating the phenotype of the transgenic plants. Alternatively, the vectors containing putative desaturase sequences can be expressed in leaves or used to generate transgenic crown galls. 
     The resulting desaturase sequences identified and isolated using methods such as those disclosed above are then cloned into plant expression and transformation vectors such as those disclosed below using well known methods in molecular biology such as those disclosed in Sambrook, Fritsch and Maniatis, Molecular Cloning: A Laboratory Manual, 2 nd  edition (1989) or Current Protocols in Molecular Biology, F. M. Ausubel et al., eds. (1987). 
     Expression of Desaturase Genes 
     For expression of a desaturase polypeptide, functional transcriptional and translational initiation and termination regions are operably linked to the DNA encoding the desaturase polypeptide. Transcriptional and translational initiation and termination regions are derived from a variety of sources, including the DNA to be expressed, genes known or suspected to be capable of expression in the desired system, expression vectors, chemical synthesis or from an endogenous locus in a host cell. Expression in a plant tissue and/or plant part provides certain advantages, particularly where the tissue or part is one that is easily harvested, such as seed, leaves, fruits, flowers, roots, etc. Expression can be targeted to that location within the plant by using specific regulatory sequences, such as those of U.S. Pat. Nos. 5,463,174, 4,943,674, 5,106,739, 5,175,095, 5,420,034, 5,188,958 and 5,589,379, which are hereby incorporated by reference in their entirety and for the specific sequences disclosed therein. One particularly useful localization of GLA produced by this invention is in the seed tissue of host plant cells. To direct expression in the seed, seed specific promoters may be used to direct expression of the appropriate desaturases. Examples of such seed specific promoters include those disclosed in U.S. Pat. Nos. 5,623,067, 6,342,657 and 6,642,437, which are hereby incorporated by reference in their entirety and for the specific sequences disclosed therein. 
     Expression in a host cell can be accomplished in a transient or stable fashion. Transient expression can occur from introduced constructs that contain expression signals functional in the host cell, but where the constructs do not replicate and rarely integrate in the host cell or where the host cell is not proliferating. Transient expression also can be accomplished by inducing the activity of a regulatable promoter operably linked to the gene of interest, although such inducible systems frequently exhibit a low basal level of expression. Stable expression can be achieved by introduction of a construct that can integrate into the host genome or that autonomously replicates in the host cell. Suitable selection markers include resistance to the herbicide Basta provided by the pat (phosphothricin acetyl transferase) gene and resistance to kanamycin provided by the nptII (neomycin phosphotransferase) gene, among other genes known in the art. Stable expression of the gene of interest can be selected for through the use of a selectable marker located on or transfected with the expression construct, followed by selection for cells expressing the marker. When stable expression results from integration, integration of constructs can occur randomly within the host genome or can be targeted through the use of constructs containing regions of homology with the host genome sufficient to target recombination with the host locus. Where constructs are targeted to an endogenous locus, all or some of the transcriptional and translational regulatory regions can be provided by the endogenous locus. 
     For expression of the desaturase polypeptide in seeds a seed-specific promoter can be employed. Examples of such promoters include the oleosin or linin promoters. The oleosin promoter is disclosed in U.S. Pat. No. 5,792,922 and the linin promoter is disclosed in U.S. Pat. No. 6,777,591. 
     When it is desirable to express more than one distinct gene, the genes can be contained within a single construct or the genes can be on separate vectors. In either case, one of skill in the art would exercise judicious choice in choosing regulatory regions, selection means and methods of propagation of the introduced construct(s) to provide for optimal expression levels of all enzymes required for the synthesis of the desired products. 
     Constructs comprising the gene of interest may be introduced into a host cell by standard techniques. These techniques include transfection, infection, biolistic impact, electroporation, microinjection, scraping or any other method that introduces the gene of interest into the host cell (see U.S. Pat. Nos. 4,743,548, 4,795,855, 5,068,193, 5,188,958, 5,463,174, 5,565,346 and 5,565,347). For convenience, a host cell that has been manipulated by any method to take up a DNA sequence or construct will be referred to as “transformed” or “recombinant” herein. The subject host will have at least have one copy of the expression construct and may have two or more, depending upon whether the gene is integrated into more than one site in the genome, with multiple copies at one loci, is amplified and/or is present on an extrachromosomal element having multiple copy numbers. 
     A variety of plant transformation methods are known. The Δ6- and Δ12-desaturase genes can be introduced into plants through  Agrobacterium  co-cultivation by a leaf disk transformation-regeneration procedure as described by Horsch et al., Science 227: 1229, 1985. Other methods of  Agrobacterium -mediated transformation, such as co-cultivation of protoplast (Horsch et al., Science 223:496, 1984; DeBlock et al., EMBO J. 2:2143, 1984), suspension culture of transformed cells (Barton et al., Cell 32:1033, 1983) or vacuum infiltration of flowers (Bechtold et al., CR Acad Scie III, Sci Vie 316:1194, 1993; Wang et al., Plant Cell Rep 22:274, 2003), can also be used and are within the scope of this invention. In a preferred aspect, plants are transformed with  Agrobacterium -derived or  Agrobacterium -immobilized vectors such as those described in Klee et al., Annu Rev Plant Physiol 38: 467, 1987. However, other methods are available to insert the Δ6- and Δ12-desaturase genes of the present invention into plant cells. Such alternative methods include, but not limited to, biolistic approaches (Klein et al., Nature 327:70, 1987), protoplast approaches (Shillito and Potrykus, Recombinant DNA Methodology 687, 1989; Davey et al., Plant Mol Biol 13:273, 1989) chemically-induced DNA uptake (Töpfer et al., Plant Cell 1:133, 1989) and use of viruses or pollen (Ohta, PNAS 83:715, 1986) as vectors. 
     When necessary for the transformation method, the Δ6- and Δ12-desaturase genes of the present invention can be inserted into a plant transformation vector, e.g., the binary vector described by Bevan (1984) Nucleic Acids Res. 12, 8111. Plant transformation vectors can be derived by modifying the natural gene transfer system of  Agrobacterium tumefacians . The natural system comprises large Ti (tumor-inducing)-plasmids containing a large segment, known as T-DNA, which is transferred to transformed plants. Another segment of the Ti plasmid, the vir region, is responsible for T-DNA transfer. The T-DNA region is bordered by terminal repeats. In the modified binary vectors the tumor-inducing genes have been deleted and the functions of the vir region are utilized to transfer foreign DNA bordered by the T-DNA border sequences. The T-region also contains a selectable marker for antibiotic resistance and a multiple cloning site for inserting sequences for transfer. Such engineered strains are known as “disarmed” A. tumefaciens  strains and allow the efficient transformation of sequences bordered by the T-region into the nuclear genomes of plants. 
     Surface-sterilized leaf disks are inoculated with the “disarmed” foreign DNA-containing  A. tumefaciens , cultured for two days and then transferred to antibiotic-containing medium. Transformed shoots are elected after rooting in medium containing the appropriate antibiotic, transferred to soil and regenerated. 
     A transformed host cell can be identified by selection for a marker contained on the introduced construct. Alternatively, a separate marker construct may be introduced with the desired construct, as many transformation techniques introduce many DNA molecules into host cells. Typically, transformed hosts are selected for their ability to grow on selective media. Selective media may incorporate an antibiotic or lack a factor necessary for growth of the untransformed host, such as a nutrient or growth factor. An introduced marker gene therefore may confer antibiotic resistance or encode an essential growth factor or enzyme and permit growth on selective media when expressed in the transformed host cell. Desirably, resistance to kanamycin and the amino glycoside G418 are of interest (see U.S. Pat. No. 5,034,322). Selection of a transformed host can also occur when the expressed marker protein can be detected, either directly or indirectly. The marker protein may be expressed alone or as a fusion to another protein. The marker protein can be detected by its enzymatic activity; for example, β-galactosidase can convert the substrate X-gal to a colored product and luciferase can convert luciferin to a light-emitting product. The marker protein can be detected by its light-producing or modifying characteristics, for example, the green fluorescent protein of  Aequorea victoria  fluoresces when illuminated with blue light. Antibodies can be used to detect the marker protein or a molecular tag on, for example, a protein of interest. Cells expressing the marker protein or tag can be selected, for example, visually or by techniques such as FACS or panning using antibodies. 
     Transformation of Safflower 
     At least two basic distinct methods exist for the transformation of safflower plants: (1) shoot regeneration from a callus, which is induced from co-cultivated cotyledons and (2) multiple shoot regeneration directly from co-cultivated excised meristems. 
     Method 1 involves induction of a callus from cotyledonary explants subsequent to co-cultivation with  Agrobacterium  (Ying et al., Plant Cell Rep 11:581, 1992); Orlikowska et al., PCTOC 40:85, 1995). The method consists of co-cultivating excised cotyledons during 3 days on callus induction medium (MS salts with B5 vitamins). Explants are transferred to shoot formation medium (MS salts, B5 vitamins and carbenicillin) and cultured for 2 days and then transferred to the same medium containing kanamycin. After 2 to 3 weeks, regenerating leafy structures are transferred together with underlying explant tissue to shoot elongation medium (½MS salts and MS vitamins) containing Geneticin®. After an additional 2 to 3 weeks, elongating shoots are detached from the original explant tissue and transferred to the same medium, at which point the cut ends of non-transformed or chimeric shoots rapidly turn brown while transgenic shoots remain healthy. Healthy shoots are transferred to rooting medium (½MS salts and MS vitamins) when at least 10 mm in length. An average of 2-3 shoots regenerate from one explant. 
     With method 2, multiple shoots are briefly induced from excised meristems prior to cocultivation with  Agrobacterium  (Rao and Rohini, Plant Biotechnol 16:201, 1999); Rohini and Rao, Annals Bot 86:1043, 2000). It involves using a needle to prick the embryo axis of germinating seeds that have had one of the cotyledons removed at the cotyledonary node. The embryo is then immersed and gently agitated at 28-30° C. in a suspension of  Agrobacterium  in Winans&#39;s AB medium for 10 minutes. Following co-cultivation on semi-solid MS basal medium for 24 hours, embryo axes are washed thoroughly with 500 μg/ml of cefotaxime in liquid MS basal medium with gentle agitation (80 rpm) for 1 hour and placed on autoclaved Soilrite (vermiculite equivalent) (Chowgule Industries Ltd. Bangalore, India) moistened with water for germination under aseptic conditions in a growth room. After 5 to 6 days, the germlings are transferred to Soilrite in pots and allowed to grow under growth room conditions for at least 10 days before they are transferred to the greenhouse. The pots are initially covered with polythene bags to maintain humidity. The growth chamber is maintained at 26-28° C. under a 14-hour photoperiod with a fluorescent light. In contrast to method 1, the majority of shoots produced with this method generally do not show vitrification. The developing plantlets might be chimeric and, in that case, successful transformation depends on whether T-DNA is integrated in the meristematic cell layer that generates the future reproductive organs. This method requires substantially more starting material (mature seed) and growth chamber space than method 1. 
     A preferred aspect of the present disclosure provides transgenic safflower plants or progeny of these plants expressing DNA encoding desaturases that overproduce GLA. Safflower is an advantageous host plant because it is widely used as a source of vegetable oils. Safflower plant cells are transformed with the isolated DNA encoding Δ6-desaturase or Δ6-desaturase and Δ12-desaturases by any of the plant transformation methods described above. The transformed safflower plant cell, usually in a callus culture or leaf disk, is regenerated into a complete transgenic plant by methods well known to one of ordinary skill in the art (e.g., Horsch et al., Science 227:1129, 1985). Since progeny of transformed safflower plants inherit the DNA encoding desaturase genes, seeds or cuttings from transformed plants are used to maintain the transgenic plant line. 
     In one specific aspect, the method comprises introducing DNA encoding Δ6-desaturase into safflower plants that lack GLA or have low levels of GLA but produce LA. In another aspect, the method comprises introducing one or more expression vectors that comprise DNA encoding Δ12-desaturase and Δ6-desaturase safflower plants that are deficient in both GLA and LA. Accordingly, safflower plants deficient in both LA and GLA are induced to produce LA by the expression of Δ12-desaturase and GLA is then generated due to the expression of Δ6-desaturase. Expression vectors comprising DNA encoding Δ12-desaturase or Δ12-desaturase and Δ6-desaturase can be constructed by methods of recombinant technology known to one of ordinary skill in the art (Sambrook et al., 1989) and the published sequence of Δ12-desaturase (Wada et al., Nature (London) 347:200, 1990). Examples of such vectors are disclosed herein. 
     Oil Containing GLA 
     The resulting GLA in safflower plants can be extracted from various safflower plant parts, particularly seeds, utilizing methods well known in the art as described above. In particular, seeds are harvested and the oil from the safflower seed can be extracted, typically by crushing the seed, and then refined using any conventional method. Methods for extracting oil from safflower seeds are well known in the art and are presented in sources such as Smith, J. R., Safflower, AOCS Press, pp. 185-212 (1996). 
     The GLA produced using the subject methods and compositions may be found in the host plant tissue and/or plant part as free fatty acids or in esterified forms, such as acylglycerols, phospholipids, sulfolipids or glycolipids, and may be extracted from the host cell through a variety of means well known in the art. Such means may include extraction with organic solvents, sonication, supercritical fluid extraction using for example carbon dioxide and physical means such as presses or combinations thereof. Of particular interest is extraction with hexane, propane, acetone or ethanol. 
     The GLA described herein can be included in nutritional and personal care compositions. Examples of nutritional compositions invention include but are not limited to infant formulas, dietary supplements, dietary substitutes and rehydration compositions. For example, the composition may be added to food of any type including but not limited to margarines, modified butters, cheeses, milk, yogurt, chocolate, candy, snacks, salad oils, cooking oils, cooking fats, meats, fish and beverages. Examples of personal care compositions include skin creams, balms and lotions, moisturizers, tanning and after tanning products, shampoos, hair conditioners and lipsticks. Examples of uses to which the GLA of this invention can be applied are described, for example, in U.S. Pat. Nos. 6,635,451 and 5,709,888, which are hereby incorporated by reference in their entirety and for the specific uses disclosed therein. 
     The patents cited herein are incorporated by reference in their entirety. The following Examples are provided by way of illustration and are not intended to limit the scope of the invention.

Transgenic plants were grown and seed were harvested. 
     Measurement of fatty acid levels was performed in seeds derived from transgenic plants. Seeds were collected from transgenic plants and fatty acid composition was determined by gas chromatography using a modification of a method described in “Official Methods and Recommended Practices of the AOCS”, 5 th  Ed., Method Ce 1-62, American Oil Chemists Society: Champaign, Ill. (1997). In this method, oil is hexane extracted from the seed, hydrolyzed with hydrochloric acid and reacted with methanol to form methyl esters. The methyl esters are then quantified against an internal standard by gas chromatography. 
     The fatty acid composition in 10 seed pools of T1 seed of transgenic plants expressing the pSBS4766 construct are shown in Table 1 below. The activity of the Δ6-desaturase gene is clearly evidenced by the presence of GLA in the transgenic lines. While GLA ranges from 0.03% to 0.04% in the S317 controls in Table 1, it ranges form 0.5% to 30.8% in the T1 pooled seeds. This is over a fifty-fold increase in the concentration of GLA. Small but significant increases in the 18:4 are seen in the lines with the highest GLA. This is expected, as the Δ6-desaturase gene can act both on 18:2 to produce GLA and 18:3 (ALA) to produce 18:3. The activity of the Δ12-desaturase is evidenced by the decrease in 18:1 fatty acids. In the S317 controls in Table 1, the OA ranges from 73.76% to 75.8% while in the transgenic lines in ranges from 3.68% to 73.51%. Overall, the data show a wide range of GLA concentrations that can be achieved in safflower via this invention.

     The single seed data follow the trend seen in the pooled seed data. Since T1 lines are still segregating, some variability can be present in single seed samples due to null, heterozygous and homozygous insertions. Observed are GLA concentrations ranging from 1.4% (Table 3: seed 1 in line 1, S1-1) to 50.8% (Table 7: seed 2 line 27, S27-2). Lines with seed oil profiles similar to those from either the single seed data or pooled seed data may be obtained. Certain lines did not set seed. Those that set seed were selected for the study. 
     Fatty acid composition of seed from T1 and T2 generations of lines expressing the pSBS4766 construct is shown below in Table 8.

     Fatty acid composition of T2 seed is consistent with that measured in T1 seed. These data show that the transgene is stable and heritable, producing consistent elevations in GLA across generations. 
     Example 2 
     Plasmid pSBS4119 and Transgenic Plants Expressing this Plasmid 
       FIG. 9  shows the map of a construct used to express the Δ6-desaturase from  Saprolegnia Diclina . The plant selectable marker used in this construct was pat which corresponds to the phosphinothricin acetyl transferase gene from  Streptomyces viridochromogenes . The bacterial marker used in this construct was SpecR. The base binary vector used to construct this vector is a derivative of pPZP200. See Hajdukiewicz et al., Plant Mol Biol 25: 989, 1994. The sequence of the insert contained within the borders of the pPZP200 plasmid is shown below.

     Transformation of safflower with this construct was performed by SemBioSys Genetics Inc. (Calgary, Canada). Techniques utilized by SemBioSys Genetics Inc. include those described in WO 2004/111244, which is hereby incorporated by reference in its entirety. Transgenic plants will be grown and seed will be harvested. 
     Seeds were collected from transgenic plants and fatty acid composition was performed using a modification of a gas chromatographic method described in “Official Methods and Recommended Practices of the AOCS”, 5 th  Ed., Method Ce 1-62, American Oil Chemists Society: Champaign, Ill. (1997). 
     As shown below in Table 9, GLA levels ranged from 11.41% (line 4119-23-1) to 72.89% (line 4119-21-3) in T1 seed from transgenic lines expressing Δ6-desaturase from  S. diclina  in the pSBS4119 construct. GLA levels over 60% were obtained in several transgenic lines. Since T1 lines are still segregating, measurements of single seed samples can vary due to null, heterozygous or homozygous insertions. GLA levels in Centennial controls and Null control lines were not detectable. The Centennial variety is naturally high in LA and transgenic expression of Δ6-desaturase alone is sufficient to increase GLA levels.

     Example 3 
     Plasmid pSBS4763 and Transgenic Plants Expressing this Plasmid 
       FIG. 10  shows the map of a construct used to express the Δ6-desaturase from  Mortierella alpina . The plant selectable marker used in this construct was pat which corresponds to the phosphinothricin acetyl transferase gene from  Streptomyces viridochromogenes . The bacterial marker used in this construct was SpecR. The base binary vector used to construct this vector is a derivative of pPZP200. See Hajdukiewicz et al., Plant Mol Biol 25: 989 (1994). The sequence of the insert contained within the borders of the pPZP200 plasmid is shown below.

     Transformation of safflower with this construct was performed by SemBioSys Genetics Inc. (Calgary, Canada). Techniques utilized by SemBioSys Genetics Inc. include those described in WO 2004/111244, which is hereby incorporated by reference in its entirety. Transgenic plants will be grown and seed will be harvested. 
     Seeds were collected from transgenic plants and fatty acid composition was performed using a modification of a gas chromatographic method described in “Official Methods and Recommended Practices of the AOCS”, 5 th  Ed., Method Ce 1-62, American Oil Chemists Society: Champaign, Ill. (1997). 
     As shown below in Table 10, GLA levels ranged from 7.8% (line 4763-13-2) to 50.19% (line 4763-28-1) in T1 seed from transgenic lines expressing Δ6-desaturase from  M. alpina  in the pSBS4763 construct. Since T1 lines are still segregating, measurements of single seed samples can vary due to null, heterozygous or homozygous insertions. GLA levels in Centennial controls and Null control lines were 0.05 or below. LA levels in Centennial are naturally high and GLA levels in Centennial can be increased with the expression of Δ6-desaturase only.
