Description: TITLE NOVEL GENE COMBINATIONS THAT ALTER THE QUALITY AND FUNCTIONALITY OF SOYBEAN OIL FIELD OF THE INVENTION This invention relates to novel gene combinations that result in novel lipid composition of soybean seeds and the oil extracted from such soybean seeds. These novel soybean gene combinations provide an alternative to the production of more expensive oils and to the chemical modification of oil to provide specific functional qualities and health attributes. BACKGROUND OF THE INVENTION Plant lipids have a variety of industrial and nutritional uses and are central to plant membrane function and climatic adaptation. These lipids represent a vast array of chemical structures, and these structures determine the physiological and industrial properties of the lipid. Many of these structures result either directly or indirectly from metabolic processes that alter the degree of unsaturation of the lipid. Different metabolic regimes in different plants produce these altered lipids. and either domestication of exotic plant species or modification of agronomically adapted species is usually required to economically produce large amounts of the desired lipid. Plant lipids find their major use as edible oils in the form of triacylglycerols. The specific performance and health attributes of edible oils are determined largely by their fatty acid composition. Most vegetable oils derived from commercial plant varieties are composed primarily of palmitic (16:0), stearic (18:0), oleic (18:1), linoleic (18:2) and linolenic (18:3) acids. Palmitic and stearic acids are, respectively, 16- and 18-carbon-long, saturated fatty acids. Oleic, linoleic. and linolenic acids are 18-carbon-long, unsaturated fatty acids containing one, two, and three double bonds, respectively. Oleic acid is referred to as a mono-unsaturated fatty acid, while linoleic and linolenic acids are referred to as poly- unsaturated fatty acids. The relative amounts of saturated and unsaturated fatty acids in commonly used, edible vegetable oils are summarized below (Table 1). TABLE 1 Percentages of Saturated and Unsaturated Fatty Acids in the Oils of Selected Oil Crops Saturated Mono-unsaturated Poly-unsaturated Canola 6% 58% 36% Soybean 15% 24% 61% Corn 13% 25% 62% Peanut 18% 48% 34% Safflower 9% 13% 78% Sunflower 9% 41% 51% Cotton 30% 19% 51% Many recent research efforts have examined the role that saturated and unsaturated fatty acids play in reducing the risk of coronary heart disease. In the past, it was believed that mono-unsaturates, in contrast to saturates and poly-unsaturates, had no effect on serum cholesterol and coronary heart disease risk. Several recent human clinical studies suggest that diets high in mono-unsaturated fat and low in saturated fat may reduce the "bad" (low- density lipoprotein) cholesterol while maintaining the "good" (high-density lipoprotein) cholesterol (Mattson et al. (1985) Journal of Lipid Research 26:194-202). A vegetable oil low in total saturates and high in mono-unsaturates would provide significant health benefits to consumers as well as economic benefits to oil processors. As an example, canola oil is considered a very healthy oil. However, in use, the high level of poly-unsaturated fatty acids in canola oil renders the oil unstable, easily oxidized, and susceptible to development of disagreeable odors and flavors (Gailliard (1980) in The Biochemistry of Plants Vol. 4, pp. 85-116, Stumpf, P. K.. ed., Academic Press, New York). The levels of poly-unsaturates may be reduced by hydrogenation, but the expense of this process and the concomitant production of nutritionally questionable trans isomers of the remaining unsaturated fatty acids reduces the overall desirability of the hydrogenated oil (Mensink et al. (1990) New England J. Medicine N323: 439-445). Similar problems exist with soybean oil and as noted in Table 1, commodity soybean oil typically contains over twice the saturated fat content of canola oil. Mutation-breeding programs have met with some success in altering the levels of poly-unsaturated fatty acid levels found in the edible oils of agronomic species. Examples of commercially grown varieties are high (85%) oleic sunflower and low (2%) linolenic flax (Knowles (1980) in World Conference on Biotechnology for the Fats and Oils Industry Proceedings. Applewhite, T. H., ed., American Oil Chemists' Society, pp. 35-38). Similar commercial progress with the other plants shown in Table 1 has been elusive, largely due to the difficult nature of the procedure and the pleiotropic effects of the mutational regime on plant hardiness, yield potential and the environmental instability of the low poly-unsaturate trait. Above all, the inability to consistently produce an oil of defined composition from season to season and in differing locations has made the commercial production of low poly- unsaturate soybean oil infeasible. The discovery of a method for altering the expression of the enzymes responsible for introduction of the second (international patent publication WO 94/11516) and third (international patent publication WO 93/11245) double bonds into soybean seed storage lipid in a directed manner has allowed the production of soybeans with a high mono- unsaturated, very low polyunsaturated fatty acid content and especially a very low linolenic acid content. The genetic combination of these two transgene profiles described in the instant invention leads to a soybean line with minimal poly-unsaturates and high mono- unsaturates and extreme environmental stability of the seed fatty acid profile. Soybeans with decreased levels of saturated fatty acids have been described resulting from mutation breeding (Erickson, E. A. et al., (1994) J. Hera . 79:465-468; Schnebly, S. R. et al. (1994) Crop Sci. 34:829-833; and Fehr, W. R. et al. (1991) Crop Sci. 31:88-89) and transgenic modification (U.S. Patent No. 5,530,186). The demonstration of the combination of these two traits in a single soybean line in this invention brings the health benefits of a high mono-unsaturate, low saturate oil to soybean production. While oils with low levels of saturated fatty acids are desirable from the standpoint of providing a healthy diet, fats that are solid at room temperature are required for their functional properties in some foods. Such applications include the production of non-dairy margarines and spreads, and various applications in confections and in baking. Many animal and dairy fats provide the necessary physical properties, but they also contain both cholesterol and the cholesterogenic medium chain fatty acids. An ideal triglyceride for solid fat applications should contain a predominance of the very high melting, long chain fatty acid stearic acid and a balance of mono-unsaturated fatty acid with very little polyunsaturated fat. Natural plant solid fat fractions typically have a triacylglyceride structure with saturated fatty acids occupying the sn-1 and sn-3 positions of the triglycerides and an unsaturated fatty acid at the sn-2 position. This overall fatty acid composition and triglyceride structure confers an optimal solid fat crystal structure and a maximum melting point with minimal saturated fatty acid content. The natural fat prototype for this high melting temperature vegetable fat is cocoa butter. The fatty acid composition of cocoa butter is 26% palmitic (16:0), 34% stearic (18:0), 35% oleic (18:1), and 3% linoleic(18:2) acids. This fatty acid profile gives cocoa butter a melting point range of from 25° to 36°C depending upon its precise crystal structure. The high price and fluctuating supply of cocoa butter has led to several processes for the production of cocoa butter substitutes and margarine stocks by fractionating other oils with relatively high 18:0 content or catalytic hydrogenation of high polyunsaturated oils followed by fractionation of the product. Oilseeds capable of producing directly high stearate, low polyunsaturate oils would be advantageous in that both the cost of hydrogenation and the undesirable side products of hydrogenation, trans monounsaturated fatty acids, could be avoided. In addition, the fractionation process could be made more cost effective or possibly eliminated if the melting temperature range of the vegetable fat produced were high enough. Oil biosynthesis in plants has been fairly well-studied [see Ηarwood (1989) in Critical Reviews in Plant Sciences. Vol. 8 (1): 1-43]. The biosyntheses of palmitic, stearic and oleic acids occur in the plastids by the interplay of three key enzymes of the "ACP track": palmitoyl-ACP elongase, stearoyl-ACP desaturase and the acyl-ACP thioesterases. Of these three enzyme types, the acyl-ACP thioesterases function to remove the acyl chain from the carrier protein (ACP) and thus away from the metabolic pathway. Oleoyl-ACP thioesterase catalyzes the hydrolysis of oleoyl-ACP thioesters at relatively high rates, although it also catalyzes the hydrolysis of palmitoyl-ACP and stearoyl-ACP at much lower rates. This multiple activity leads to substrate competition between enzymes, and it is the competitions of acyl-ACP thioesterase and palmitoyl-ACP elongase for the same substrate and of acyl-ACP thioesterase and stearoyl-ACP desaturase for the same substrate that contributes to the production of the palmitic and stearic acids found in the triacylglycerides of vegetable oils. Once removed from the ACP track, fatty acids are exported to the cytoplasm and there they are used to synthesize acyl-coenzyme A. These acyl-CoAs are the acyl donors for at least three different glycerol acylating enzymes (glycerol-3-P acyltransferase, 1-acyl- glycerol-3-P acyltransferase and diacylglycerol acyltransferase) which incorporate the acyl moieties into triacylglycerides during oil biosynthesis. These acyltransferases show a strong, but not absolute, preference for incorporating saturated fatty acids at sn-1 and sn-3 positions and monounsaturated fatty acids at the sn-2 position of the triglyceride. Thus, altering the fatty acid composition of the acyl pool will drive a corresponding change in the fatty acid composition of the oil. Furthermore, there is experimental evidence that because of this specificity, plants can produce cocoa butter substitutes or other specialty fats if there is the correct composition of fatty acids available in the substrate pool for the acyltransferases [Bafor et al, (1990) JAOCS 67:217-225]. Based on the above discussion, one approach to changing the levels of palmitic, stearic and oleic acids in vegetable oils is to alter their levels in the cytoplasmic acyl-CoA pool used for oil biosynthesis. Manipulation of stearate levels has been described (Knutzon, D.S. et al., (1992) Proc. NatlAcad. Sci. USA 89(7): 2624-2628). Seeds from both B. campestris and B. napus plants were produced by antisense expression of a cDNA encoding the B. campestris stearoyl-ACP desaturase, the enzyme responsible for introducing the first double bond into 18 carbon fatty acids in plants, using a seed specific promoter region. These seeds produced oils high in stearic acid, that also contained elevated levels of linolenic acid (18:3), when compared to seeds from unmodified plants from the same species. Elevated levels of stearic acid have been obtained in soybean by a similar underexpression of stearoyl-ACP desaturase (U.S. Patent No. 5,443,974) and in canola by over expression of an acyl-ACP thioesterase (U.S. Patent No. 5,530,186). Mutation breeding has also produced soybean lines with elevated levels of stearic acid in their seed oils (Graef, G. L. et al., (1985) JAOCS 62:773-775; Hammond, E. G. and W. R. Fehr, (1983) Crop Sci. 23:192-193). Poly-unsaturated fatty acids contribute to the low melting point of liquid vegetable oils. In high saturate oils their presence is a detriment in that they decrease the melting point, and therefore even higher levels of undesirable saturated fatty acid are required to achieve a plastic fat at room temperature. Additionally, when used in baking and confectionery applications high levels of poly-unsaturates leads to oxidative instability as described above for liquid oils. Thus for maximum utility a high saturate fat produced in soybean should contain saturated fatty acids, mono-unsaturated fatty acid and as little polyunsaturated fatty acid as possible. Gene combinations discovered in this invention provide novel fatty acid profiles in soybean which meet these criteria.

BIOLOGICAL DEPOSIT The following soybean seed has been deposited with the American Type Culture Collection (ATCC), 10801 University Boulevard, Manassas, VA 20110-2209, and bears the following designation, accession number and date of deposit. Soybean Accession Number Date of Deposit Soybean T1S ATCC 203033 May 14, 1998 Soybean L9216116-109 ATCC XXXXXX April ??, 1999 BRIEF DESCRIPTION OF THE FIGURES AND SEQUENCE DESCRIPTIONS The invention can be more fully understood from the following detailed description, a description of the four figures, and the Sequence Descriptions which form a part of this application. Figure 1 depicts the Solid Fat Content (SFC) profiles of a high stearic, and four different high stearic and high oleic acid soybean oils compared to a soft tub vegetable oil spread. Only the 22% high stearic and high oleic (HS HO A) performs as a spread product. The SFC profiles of the remaining oils indicated that these oils would not perform as a spread product. Figure 2 depicts the relative oxidative stabilities (OSI) of several unblended and blended oils. A high oleic acid content coupled with a low polyunsaturate content is necessary to achieve high oxidative stability. Blended oils such as soybean oil (SO) mixed with palm oil (PO), or high stearic (HS) oil mixed with palm oil or fully hydrogenated oil may perform well as margarine or spread products based upon SFC profile. Figure 3 shows that blending high stearic and high oleic acid oils (HS/HO C and HS/HO D), with hardstocks such as palm oil or fully hydrogenated soybean oils, improves their SFC profiles to conform with the characteristics of a vegetable oil spread. Figure 4 shows that very high stearic acid oils have SFC profiles consistent with butter and hardstock oils. The sequence descriptions summarize the Sequences Listing attached hereto. The Sequence Listing contains one letter codes for nucleotide sequence characters and the three letter codes for amino acids as defined in the IUPAC-IUB standards described in Nucleic Acids Research 73:3021-3030 (1985) and in the Biochemical Journal 219 (No. 2j:345-373 (1984), and the symbols and format used for all nucleotide and amino acid sequence data further comply with the rules governing nucleotide and/or amino acid sequence disclosures in patent applications as set forth in 37 C.F.R. §1.821-1.825 and WIPO Standard St.25.

A soybean plant having this fatty acid profile is produced by the following steps which comprise: (a) crossing a first parent soybean plant wherein the Cl 8: 1 content comprises at least 80% of the total seed fatty acid and the first parent further comprises at least one transgene copy of a soybean nucleic acid fragment encoding a delta- 12 desaturase enzyme with a second parent comprising either a mutation such as the fan allele for decreased seed linolenic acid content, or at least one transgene copy of a soybean nucleic acid fragment encoding a delta- 15 desaturase enzyme and further wherein the C 18:3 content comprises less than 4% of the total seed fatty acid; (b) obtaining hybrid seeds from the cross of step (a), germinating said seeds, growing and producing a segregating population of soybean plants through one or more cycles of self-pollination; and (c) selecting the plants from the segregating population of step (b) which produce seeds having said fatty acid profile. Also of interest are seeds obtained from such a plant, oil obtained from these seeds, products made from the hydrogenation, fractionation, interesterification or hydrolysis of such oil and by-products made during the production of this oil. The general method used to assemble the specific genotypes responsible for the novel seed fatty acid profiles described herein is as follows: 1) Parental lines chosen for their seed fatty acid profile were cross-pollinated by manual transfer of pollen from the flowers of one parent plant to the emasculated flowers of the second parent plant. 2) Mature seeds from the cross pollinated flowers were planted to produce F 1 plants which were allowed to self pollinate to produce an F2 population of seeds carrying varying doses of genes involved in producing the seed fatty acid phenotype of the two parents. 3) A small chip of the mature seed was removed from a portion of the cotyledon which is not in direct contact with the embryonic axis. The relative content of the five main fatty acids comprising the seed lipids was determined by gas liquid chromatography as described in WO 93/11245, and the remaining portions of seeds chosen on the basis of the fatty acid profile of the analyzed chip were planted. The chosen F2 plants were allowed to self pollinate and produce F3 seeds. The above analytical procedure was repeated on single seeds from this generation and on the bulk seed lot from this generation. As an alternative, the F2 seed population can be grown and self pollinated without prior selection and bulk seed from individual plants in the resulting F2 plants analyzed to select F2:3 families on the basis of single plant bulk seed fatty acid analysis. Once identified lines with desired fatty acid profiles can be advanced as self pollinated populations to maintain and test the seed fatty acid profile. To produce lines with concomitantly high levels of oleic acid and low levels of polyunsaturated fatty acids, a delta- 12 desaturase down-regulated transgenic line described in WO 97/40698 was chosen as one parent. To produce soybean lines low in poly-unsaturates but high in saturated fatty acids a soybean line that contained a mutation resulting in high levels of stearic acid was chosen as the second parent. An example of such a line can be found in U.S. Patent No. 5,557,037, the disclosure of which is hereby incorporated by reference. That patent discloses the soybean line A6 which carries a mutation at a locus designated as the fasa locus. To produce lines with concomitantly high levels of oleic acid and very low levels of saturated fatty acids, the delta- 12 desaturase down-regulated line was chosen as one parent, and a line with very low levels of palmitic acid was chosen as the second parent. One approach was to use a second parent containing a combination of genes, such a line can be found in U.S. Patent No. 5,585,535, the disclosure of which is hereby incorporated by reference. Another approach is to use the line disclosed in WO 96/06936 as the second parent wherein a palmitoyl-ACP thioesterase construct is disclosed that is in the sense orientation, the integration of which results in a reduction of activity. To further decrease the level of the poly-unsaturated fatty acid linolenic acid and to enhance the environmental stability of the low poly-unsaturated fatty acid phenotype the delta- 12 desaturase down regulated transgenic line was chosen as one parent and either a transgenic line with down regulated expression of the delta- 15 desaturase or a mutant line with a similar linolenic acid phenotype was chosen as the second parent. An example of a mutant line with a linolenic acid phenotype similar to that produced by down regulation of the delta-15 desaturase may be found in U.S. Patent No. 5,534,425, the disclosure of which is hereby incorporated by reference. Very high levels of saturated fatty acids in soybean seeds were produced by the combination of a mutant line producing seeds with high levels of stearic acid with a transgenic line carrying a chimeric gene for seed specific over-expression of a plant acyl-ACP thioesterase. Methods for the extraction and processing of soybean seeds to produce soybean oil and meal are well known throughout the soybean processing industry. In general, soybean oil is produced using a series of steps which accomplish the extraction and purification of an edible oil product from the oil bearing seed. Soybean oils and soybean byproducts are produced using the generalized steps shown in the diagram below. Process Impurities Removed/ Byproducts Obtained Soybean Seed 1 Oil Extraction Meal t Degumming Lecithin t Alkali or Physical Refining Gums, Free Fatty Acids, Pigments t Water Washing Soap t Bleaching Color, Soap, Metal t (Hydrogenation) t (Winterization) Stearine 1 Deodorization FFA, Tocopherols, Sterols, Volatiles t Oil Products Soybean seeds are cleaned, tempered, dehulled, and flaked which increases the efficiency of oil extraction. Oil extraction is usually accomplished by solvent (hexane) extraction but can also be achieved by a combination of physical pressure and/or solvent extraction. The resulting oil is called crude oil. The crude oil may be degummed by hydrating phospholipids and other polar and neutral lipid complexes that facilitate their separation from the nonhydrating, triglyceride fraction (soybean oil). The resulting lecithin gums may be further processed to make commercially important lecithin products used in a variety of food and industrial products as emulsification and release (antisticking) agents. Degummed oil may be further refined for the removal of impurities; primarily free fatty acids, pigments, and residual gums. Refining is accomplished by the addition of caustic which reacts with free fatty acid to form soap and hydrates phosphatides and proteins in the crude oil. Water is used to wash out traces of soap formed during refining. The soapstock byproduct may be used directly in animal feeds or acidulated to recover the free fatty acids. Color is removed through adsorption with a bleaching earth which removes most of the chlorophyll and carotenoid compounds. The refined oil can be hydrogenated resulting in fats with various melting properties and textures. Winterization (fractionation) may be used to remove stearine from the hydrogenated oil through crystallization under carefully controlled cooling conditions. Deodorization which is principally steam distillation under vacuum, is the last step and is designed to remove compounds which impart odor or flavor to the oil. Other valuable by products such as tocopherols and sterols may be removed during the deodorization process. Deodorized distillate containing these byproducts may be sold for production of natural vitamin E and other high value pharmaceutical products. Refined, bleached, (hydrogenated, fractionated) and deodorized oils and fats may be packaged and sold directly or further processed into more specialized products. A more detailed reference to soybean seed processing, soybean oil production and byproduct utilization can be found in Erickson, 1995, Practical Handbook of Soybean Processing and Utilization. The American Oil Chemists' Society and United Soybean Board. Hydrogenation is a chemical reaction in which hydrogen is added to the unsaturated fatty acid double bonds with the aid of a catalyst such as nickel. High oleic soybean oil contains unsaturated oleic, linoleic, and linolenic fatty acids and each of these can be hydrogenated. Hydrogenation has two primary effects. First, the oxidative stability of the oil is increased as a result of the reduction of the unsaturated fatty acid content. Second, the physical properties of the oil are changed because the fatty acid modifications increase the melting point resulting in a semi-liquid or solid fat at room temperature. There are many variables that affect the hydrogenation reaction which in turn alter the composition of the final product. Operating conditions including pressure, temperature, catalyst type and concentration, agitation and reactor design are among the more important parameters which can be controlled. Selective hydrogenation conditions can be used to hydrogenate the more unsaturated fatty acids in preference to the less unsaturated ones. Very light or brush hydrogenation is often employed to increase stability of liquid oils. Further hydrogenation converts a liquid oil to a physically solid fat. The degree of hydrogenation depends on the desired performance and melting characteristics designed for the particular end product. Liquid shortenings, used in the manufacture of baking products, solid fats and shortenings used for commercial frying and roasting operations, and base stocks for margarine manufacture are among the myriad of possible oil and fat products achieved through hydrogenation. A more detailed description of hydrogenation and hydrogenated products can be found in Patterson, H. B. W., 1994, Hydrogenation of Fats and Oils: Theory and Practice. The American Oil Chemists' Society. Hydrogenated oils have also become controversial due to the presence of trans fatty acid isomers that result from the hydrogenation process. Ingestion of large amounts of trans isomers has been linked with detrimental health effects including increased ratios of low density to high density lipoproteins in the blood plasma and increased risk of coronary heart disease. It would be advantageous to produce foods that currently use hydrogenated oils in a form that would be free of trans fatty acids. The term " substantially free of trans fatty acids" as used herein means a non-health threatening level of trans fatty acids. For example, such a level can range from 0.1% (i.e., an amount which cannot be reliably detected by current methods for assessing trans fatty acid levels) to an upper limit which does not pose a health risk. In the near future, the Federal government is expected to place an upper limit on the levels of trans fatty acid isomers that can be present in foods and have the designation "trans fatty acid free" . It is believed that all of the oils, margarines and spread products of the invention are expected to conform to whatever limits are imposed by governmental authorities. The limit of detection for trans isomers of fatty acids in oils is around 0.1%. (The gas chromatography method for detecting trans fatty acids in oils is outlined in AOCS Ce 1C-89). Reports of " low trans isomer oils" produced by modifications of the hydrogenation method can achieve levels of 5-20% (w/w), but usually at the cost of high saturated fatty acid levels (Allen, D. A. (1998) Lipid Technology, 10(2), 29-33). It is believed that the oils, fat products, and blended fat products, that are wholly or partially non-hydrogenated and non- chemically modified, in the instant invention, should be substantially free of trans fatty acids, i.e., they should achieve trans fatty acid concentrations of below 20% (w/w), preferably below 10%, more preferably below 5%, even more preferably below 3%, and again more preferably below 1%, and most preferably below 0.5% of the oil. Interesterification refers to the exchange of the fatty acyl moiety between an ester and an acid (acidolysis), an ester and an alcohol (alcoholysis) or an ester and ester (transesteri- fication). Interesterification reactions are achieved using chemical or enzymatic processes. Random or directed transesterification processes rearrange the fatty acids on the triglyceride molecule without changing the fatty acid composition. The modified triglyceride structure may result in a fat with altered physical properties. Directed interesterfication reactions using lipases are becoming of increasing interest for high value specialty products like cocoa butter substitutes. Products being commercially produced using interesterification reactions include but are not limited to shortenings, margarines, cocoa butter substitutes and structured lipids containing medium chain fatty acids and polyunsaturated fatty acids. Interesteri- fication is further discussed in Hui, Y. H., 1996, Bailey " s Industrial Oil and Fat Products. Volume 4, John Wiley & Sons. Fatty acids and fatty acid methyl esters are two of the more important oleochemicals derived from vegetables oils. Fatty acids are used for the production of many products such as soaps, medium chain triglycerides, polyol esters, alkanolamides, etc. Vegetable oils can be hydrolyzed or split into their corresponding fatty acids and glycerine. Fatty acids produced from various fat splitting processes may be used crude or more often are purified into fractions or individual fatty acids by distillation and fractionation. Purified fatty acids and fractions thereof are converted into a wide variety of oleochemicals, such as dimer and trimer acids, diacids, alcohols, amines, amides, and esters. Fatty acid methyl esters are increasingly replacing fatty acids as starting materials for many oleochemicals such as fatty alcohols, alkanolamides, a-sulfonated methyl esters, diesel oil components, etc. Glycerine is also obtained by the cleavage of triglycerides using splitting or hydrolysis of vegetable oils. Further references on the commercial use of fatty acids and oleochemicals may be found in Erickson, D. R., 1995, Practical Handbook of Soybean Processing and Utilization, The American Oil Chemists' Society, and United Soybean Board; Pryde, E.H., 1979, Fatty Acids, The American Oil Chemists' Society; and Hui, Y.H., 1996, Bailey's Industrial Oil and Fat Products, Volume 4, John Wiley & Sons. Those skilled in the art will appreciate that products obtained from the hydrogenation, fractionation, interesterification or hydrolysis of the oils described in the instant invention can be used to make a margarine or spread product. Furthermore, blended products can be made as described below utilizing fractionated or unfractionated oils of the invention, either in their natural state or modified by hydrogenation. fractionation, interesterification and/or hydrolysis, in combination with other ingredients to produce a margarine or spread product. Margarine is a flavored food product, commonly used as a dairy butter substitute for table or cooking purposes such as frying, baking, etc. The composition of margarine is typically 80% fat, made by blending selected fats and oils with other ingredients and fortified with Vitamin A. Examples of ingredients that can be used to make a blended fat include, but are not limited to, at least one component selected from the group consisting of fully hydrogenated soybean oil, fully hydrogenated cottonseed oil. fully hydrogenated palm oil, partially hydrogenated soybean oil, partially hydrogenated cottonseed oil, partially hydrogenated palm oil, soybean oil, corn oil, palm oil, canola oil, sunflower oil, peanut oil, safflower oil or mixtures thereof. The process of blending, and the ultimate product, can be varied for different applications. All products containing less than 80% fat require labeling as "spreads". The terms "spread" or "spread products" are used interchangeably herein. Margarine and spreads may contain one or more aqueous-phase ingredients, as well as other optional ingredients with specific functions. There are over 10 different types of margarine and spreads produced today including regular, whipped, soft-tub, liquid, diet, spreads, no-fat, restaurant, bakers, and specialty types that are all packaged as different products. In the early 1950's almost all consumer margarine was a stick variety. Sales and per capita consumption rose and surpassed that of butter in 1957. Sales increases stimulated new technological progress and new product development. Spreadable margarine, polyunsaturated margarine, and low-fat products were developed to satisfy the desire for convenience and nutritional awareness, and weight consciousness of the consumer. The first major departure from the past was the introduction of soft margarine spreadable from the refrigerator and packaged in tubs. This soft, full-fat product captured one-fourth of the margarine market by 1973. In recent years, stick table spreads account for slightly less than half of the total table spread market. The most significant recent trend is away from margarine (80%) fat to spreads containing lower fat levels. Originally introduced at 60% fat, since 1980 spread containing from 75% to less than 5% fat have appeared in the marketplace. The products are sold in stick, liquid, and soft whipped forms. Low calorie, soft and stick spreads containing 40-75% fat are usually formulated from the same oil blends as those used for the manufacture of soft and stick margarines, respectively. A detailed description of margarine and spread manufacturing practices and product characteristics can be found in Bailey's Industrial Oil and Fat Products, Fifth Edition, Volume 3, Y.H. Hui, Ed., John Wiley & Sons, Inc, New York, 1996, pp 65-114; and Bailey's Industrial Oil and Fat Products, Fifth Edition, Volume 4. Y.H. Hui, Ed., John Wiley & Sons, Inc, New York, 1996, pp 491-568. Consumer margarines are formulated by blending two or more oil basestocks with different degrees of hardness. This permits the margarines to be spreadable directly out of the refrigerator and to maintain a solid consistency at room temperature. The properties of a good performing margarine can be profiled by measuring the Solid Fat Content (SFC, see below) of the fat blend. This profile can then be used to predict the performance of other oil blends as margarine products. A detailed description of margarine formulation can be found in: Fats and Oils, Formulation and Processing for Applications, ed. R. D. O'Brien, Technomic Publishing Co, Lancaster. PA, 1998, pp 437-457. The melting characteristics and plasticity of a fat can be measured by industry standard techniques. The most commonly used methods are Solid Fat Index (SFI, AOCS Cd 10-57-93) and Solid Fat Content (SFC, AOCS Cdl6b-93(97)). SFI determinations are based on dilatometry which measures the amount of solid or liquid in a fat based on volumetric changes resulting from a fat melting to the liquid state. This technique is gradually being replaced by SFC. This method is based on pulsed, low resolution nuclear magnetic resonance (NMR) to measure the relative amounts of solid and liquid in a sample based on the difference in the rates of relaxation of protons in the two phases after the sample has been pulsed. Conversion of SFI to SFC data has not always been reliable. For a given sample, the percentage of solids is measured across temperatures generally ranging between 10° and 40°C. The entire SFC curve is required in order to understand the properties of the fat at different temperatures. The functionality of the fat is based on both the solids content and on the slope of the SFC curve at critical temperatures, for example, between room and body temperature. In this way, the plasticity of that fat can be predicted for temperatures critical to performance. For margarine or conventional oils and fats, SFC is determined using the direct, serial, non-stabilizing method. The SFC NMR direct method measures and compares signals from the solid and liquid phases. SFC is defined as the percent ratio between the NMR response obtained from the hydrogen nuclei in the solid phase versus the response from nuclei in both the solid and the liquid phases of the sample. The serial, non-stabilizing method utilizes a single set of samples that are tempered by melting and storage at 100°C for 15 minutes, holding at 60°C for 5 minutes, and at 0°C for 1 hour. The samples are then held at each recording temperature for 30 minutes and moved to the next higher temperature immediately after determination of SFC. It is believed that high stearic with high oleic oils presented here, as well as those oils with similar compositions, will be capable of producing fat products with SFC profiles of less than 20 at 25°C, preferably less than 15 at 25°C, more preferably less than 10 at 25°C, and most preferably less than 5 at 25°C, and greater than 20 at 10°C, preferably between 20 and 50 at 10°C, and most preferably between 20 and 35 at 10°C. The melting point of a fat is also an important measurement. Since fats are made up of a mixture of triglycerides which have different melting points, a sharp determination is not always possible. There are several methods common to the industry which measure melting point including capillary melting point (AOCS Cc 1-25-93), Wiley melting point (AOCS Cc2-38-91), slip point (AOCS Cc3-25-93), and dropping point (AOCS Ccl 8-80-95). Typical solid fat index values of US margarine oils are given in Table 3. The numbers are representative of commercial products. For a given type of margarine, however, specifications may vary considerably between manufacturers depending on: 1) the organoleptic characteristics desired, 2) compositional requirements to meet nutrient content claims or other information on the nutrition panel, 3) whether the product will be marketed using unrefrigerated display, and 4) the type of packaging equipment available. The solids values are indicative of finished product spreadability at refrigerator temperatures (10°C), resistance to oil-off at room temperature (21.1°C), and melt in the mouth qualities (33.3°C). TABLE 3 Typical Solid Fat Indices of U.S. Table Spreads Solid Fat Index 10° 21.1° 26.7° 33.3° 37.7° Stick 28 16 10 2 0 Soft stick 20 13 9 2.5 0 Soft tub 11 7 5 2 0.5 Liquid 3 2.5 2.5 2 1.5 Butter 32 12 7 2 0 The physical and functional aspects of a margarine product are primarily dependent upon the characteristics of its oil phase. A direct relationship exists between the fat solids content and the structure, consistency, and plasticity of the finished margarine. Margarine consistency, flavor and emulsion stability depends upon crystallized fat. In the United States, hydrogenation is the preferred process for changing the solids/liquid relationship of margarine basestocks. However, hydrogenated oils have become controversial due to the presence of trans fatty acid isomers that result from the hydrogenation process. Ingestion of large amounts of trans isomers has been linked with detrimental health effects including increased ratios of low density to high density lipoproteins in the blood plasma and increased risk of coronary heart disease. From an environmental standpoint, the use of metal catalysts in the hydrogenation process has raised issues regarding the reclamation and disposal of a toxic metal waste product. Increased public awareness of the negative aspects of hydrogenation will likely lead to significant changes in margarine formulation to reduce or eliminate the presence of industrially-modified oils. A number of methods are well known to those skilled in the art for determining oxidative stability. A standard method now commonly used to evaluate the stability of commercial cooking oils is the Oxidative Stability Index (OSI) which is measured automatically using a machine manufactured by Ominion, Inc. of Rockland, MA, USA. The OSI machine works by bubbling air through oil heated to 110°C. As the oil oxidizes, volatile organic acids, primarily formic acid, is formed which can be collected in distilled water in a cell. The machine constantly measures the conductivity of the distilled water and the induction period is determined as the time it takes for this conductivity to begin a rapid rise. It is believed that the high stearic with high oleic oils presented in the invention, in their unblended and blended forms, as well as those oils with similar compositions, will be capable of producing fat products with OSI(l 10) greater than 15, preferably greater than 25, and most preferably greater than 35. EXAMPLES The following Examples are intended to illustrate the present invention and do not constitute a limitation thereon. All temperatures are given in Celsius unless indicated otherwise. Solid Fat Content (SFC) profiles listed in these Examples report the percentage of the total fat moieties that were determined to be in the solid phase at the indicated temperature. EXAMPLE 1 Preparation of oils from soybeans and analyses of fatty acid compositions All of the oils used in these examples were prepared according to the following laboratory scale method. Harvested soybeans were heated in the microwave to 180°F, cooled to room temperature and cracked using a Roskamp TRC 650-6 Crack and Roll. Soybean hulls were removed using a Kice Aspirator and the remaining meats were heated to 180°F and flaked in a Roskamp TRC 912 Flake and Roll. Crude oil was extracted in a glass, water-jacketed extraction vessel heated to 60° for 45 minutes using a solvent to solids ratio of approximately 4:1. The hexane/oil miscella was collected and the extraction repeated. The miscella was desolventized using a rotary evaporator leaving crude oil. A volume of an 85% phosphoric acid solution equal to 0.1% (v/v) of the crude oil was added and the solution heated to 65°-70° for 10 minutes while stirring. Warm (60°) NaOH (8%) aqueous solution) was added dropwise to the oil to neutralize the free fatty acids and the H3PO 4 with an additional 0.2% wt wt excess. The solution was stirred for five minutes and the solids separated by centrifugation. The oil was water washed by adding hot water to 20% (v/v) as the sample was heated to 90° with rapid agitation. The oil and water were allowed to cool at room temperature for 10 minutes and then separated by centrifugation. The oil was dehydrated using very rapid agitation under vacuum at 85°-95° for 30 minutes or until all moisture (bubbles, condensation) had been removed. The vacuum was then broken with nitrogen. The oil was bleached by adding 2% (wt/wt) Activated Bleaching Earth (AOCS #Z1077) and the solution mixed under vacuum for 30 minutes at 85°-95° before cooling to 80°. The vacuum was broken with nitrogen and 1% (wt/wt) of diatomaceous earth was added and the mixture filtered through a prepared bed of diatomaceous earth. Citric acid was added to approximately 50 ppm, and the oil was deodorized at 240° with steam (4 mL water per 100 g oil) in a glass deodorizer for approximately 1 hour. The oil was cooled to 80° with sparging, and it was further cooled to 40° under nitrogen. The refined, bleached, and deodorized oil was stored frozen under a nitrogen atmosphere. All of the fatty acid composition analyses described in these examples were determined essentially by the methods described in AOCS Ce lc-89. Fatty acid methyl esters were prepared as follows. Ten μL oil or liquefied fat was mixed with 1 mL hexane and 0.25 mL of a 3% sodium methoxide solution for 30 minutes. Acetic acid (0.1 mL of a 10%) solution) was added, the sample was mixed and the layers separated by centrifugation. The resulting fatty acid methyl esters extracted in the hexane layer were resolved by gas chromatography (GC). Hewlett Packard 5890GC (Wilmington, DE) equipped with a SP2340 column (60 m, 0.25 mm ID, 0.20 micron film thickness) (Supelco, Bellefonte, PA). Column temperature was 150° at injection and the temperature programmed from 150° to 200° at 2°C/min over 40 minutes. Injector and detector temperatures were 215° and 230°, respectively. All compositional values reported are relative values calculated from the integrated areas measured by the GC detector. All of the SFC determinations were done essentially by the methods described in AOCS Cdl6b-93. All of the oxidative stability measurements were determined by OSI essentially by the methods described in AOCS Cdl2b-92(93). EXAMPLE 2 Solid Fat Content of Commercial Margarine Samples of commercial margarine with varying degrees of solidity were analyzed for SFC. Samples were prepared by melting the product at 100 degrees and removing the aqueous layer. The resulting fat fraction was analyzed for SFC as a function of temperature and the results are listed in Table 4. The table shows the range of solids which can be used to produce different types of margarine and spread products depending on the fat plasticity and the product form desired (e.g., soft tub, stick, low fat spread).

The seeds produced have a higher stearic acid content and lower linolenic acid content than conventional soybeans. The parents HSTl, H02, and H04 (see Table 2) are mutant lines selected by the mutagenesis protocols outlined in U.S. Patent No. 5,710,365, except different soybean lines were used as starting materials for the mutagenesis, and selection was based on variation in fatty acid content instead of carbohydrate content. HSTl is a mutant of line N85-2176 which is a high oleic, low linolenic line developed at North Carolina State University by J. W. Burton (Kuhr et al, March 26, 1987 Release Notice for N85-2124, N85-2131, and N85-2176. USDA Agric Res. Services). HSTl differs from its parent N85-2176 by virtue of its abnormally high stearic acid content (HST=high stearic), while retaining the lower linolenic acid content of N85-2176. The high stearic mutation in HSTl suppresses (is epistatic to) the high oleic gene(s) that are present in the genetic background from N85-2176. Therefore, HSTl is not high in oleic acid like N85-2176. The stearic mutation in HSTl is allelic to fasa (see Table 2) in line A6 (W. Fehr from Iowa State) and results in a similar phenotype when crossed into similar backgrounds as the fasa allele. Crosses between N85-2176 and A5 (W. Fehr from Iowa State) confirm that N85-2176 contains an allele of the fan gene (see Table 2) present in A5 that confers a similar low linolenic phenotype. Therefore, HSTl contains both a high stearic mutation (allelic to fasa) and a low linolenic mutation (allelic to fan). H02 is a DuPont proprietary mutant line selected from mutagenesis of the line N85-2176. The mutagenesis protocol was essentially the same as the one described in U.S. Patent No. 5,710,365, except that N85-2176 was used as the starting material for mutagenesis, and selection was based upon variation in fatty acid content instead of carbohydrate content. H02 differs from N85-2176 (fan) in that it has a slightly higher oleic acid content (HO=high oleic), but retains the low linolenic acid content of N85-2176. Therefore, H02 contains an unnamed mutation that confers higher oleic acid content than N85-2176 in addition to the fan gene. H04 is a DuPont proprietary mutant line selected from mutagenesis of the line A5. The mutagenesis protocol was essentially the same as the one described in U.S. Patent No. 5,710,365, except that A5 was used as the starting material for the mutagenesis, and selection was based upon variation in fatty acid content instead of carbohydrate content. H04 differs from A5 (fan) in that it has a higher oleic acid content (HO=high oleic), but retains the low linolenic acid content of A5. Therefore, H04 contains an unnamed mutation that confers higher oleic acid content than A5 in addition to the fan gene. It is believed that a derivative of A6 (fasa), or similar plant yielding seeds with an oil composition comprising a high stearic and low linolenic acid phenotype similar to that disclosed in the instant invention, would be useful for the methods described herein. High stearic and high oleic acid soybeans were developed as outlined in Example 5. All soybean oils were prepared as described in Example 1 and analyzed for fatty acid composition and solid fat content at a variety of temperatures. Tables 5 and 6 show the compositional and functional characteristics of high stearic soybean oils ranging from 15% to 22% stearic acid. In addition, four of the oils have elevated levels of oleic acid. The oil containing 22% stearic acid and a normal oleic content did not have enough solidity to meet the specifications required for a soft tub margarine (see Figure 1). However, the SFC profile of the 22% stearic acid, high oleic acid combination fell within the ranges published for commercial soft tub margarine. It is believed that high stearic combined with high oleic oils presented here, as well as those oils with similar compositions, will be capable of producing fat products with SFC profiles of less than 20 at 25°C, preferably less than 15 at 25°C, more preferably less than 10 at 25°C, and most preferably less than 5 at 25°C, and greater than 20 at 10°C, preferably between 20 and 50 at 10°C, and most preferably between 20 and 35 at 10°C. Oils with less than 22% stearic acid did not have an SFC profile consistent with margarine and spread products. Therefore, SFC profiles consistent with margarine and spread products could be obtained from unblended oils with high oleic acid concentrations combined with stearic acid concentrations of at least 22%.

The resulting blends were analyzed for fatty acid composition, solid fat content at a variety of temperatures, and oxidative stability. Table 7 shows the fatty acid compositions and OSI values of each of these blends. A graphical representation is shown in Figure 2. Blends made from high stearic/high oleic oils show oxidative stability values 4-7 fold greater than blends made from high stearic oils with normal oleic levels. It is believed that the high stearic with high oleic oils presented here, in their unblended and blended forms, as well as those oils with similar compositions, will be capable of producing fat products with OSI(l 10) greater than 15, preferably greater than 25, and most preferably greater than 35. Table 8 shows the solid fat content for each of these blends. The blended forms of high stearic/ high oleic oils demonstrating high oxidative stability (HSHO C + palm oil, and HSHO D + fully hydrogenated soybean oil) have also improved their SFC profiles as shown in Figure 3, and now conform with the curve for soft-tub margarine. It is believed that high stearic with high oleic oils presented here, in their unblended and blended forms, as well as those oils with similar compositions, will be capable of producing fat products with SFC profiles of less than 20 at 25°C, preferably less than 15 at 25°C, more preferably less than 10 at 25°C, and most preferably less than 5 at 25°C, and greater than 20 at 10°C. preferably between 20 and 50 at 10°C, and most preferably between 20 and 35 at 10°C.

The high oleic line contains a transgene copy of the soybean fatty acid desaturase gene, gmFAD2-l (Heppard, E.P. et al. (1996) Plant Physiol 110:311-319), that results in co- suppression and therefore down regulation of the gmFAD2-l message level and is described in WO 97/40698. Decreased expression of the FAD2-1 function leads to a decrease in activity of delta- 12 desaturase, and a decrease in the accumulation of poly-unsaturated fatty acids. The high oleic line is designated D2T and the typical fatty acid profile of its seed lipid is given in Table 2. The high stearate parent is a fatty acid synthesis mutant isolated from a mutagenized soybean seed population (U.S. Patent No. 5,557,037), designated A6, and containing a fatty acid mutant fasa allele. Its typical seed lipid fatty acid profile is given in Table 2. FI seeds obtained from the crosses were planted to obtain FI plants. The FI plants were then self-pollinated to obtain F2 seeds that were segregating for both of the loci affecting the seed fatty acid profile. These F2 seeds were planted and the plants were self- pollinated as in the previous generation. The relative content of the five main fatty acids in bulked seed samples from individual F2 plants was determined by gas liquid chromatography as described in WO 94/11516. Remaining seed from F2 plants containing maximum stearic and oleic acid content were selected, planted and allowed to self pollinate in order to obtain F3:4 seed. A sample of F4 seed from each F3 plant (F3:4 seed) was then submitted for GC analysis so that individual F3:4 phenotypes could be determined. F3:4 plant phenotypes tracing back to a common F2 plant ancestor were then averaged to obtain mean phenotypes for F2-derived families (F2:4 family means). Single plants and family means that were highest in oleic and stearic acid are shown in Table 9. The individual plant lines and the family means are presented in order of decreasing stearic acid in the seed fatty acids.

The increased level of stearic acid in the selected progeny from the cross relative to the D2T parent causes a decrease in the oleic acid content. EXAMPLE 6 Soybeans with High Oleic Acid and High Palmitic Acid and High Stearic Acid Content Crosses were made between soybean lines containing the D2T gene (for high oleic acid content) and soybean lines containing both afap2 allele (for high palmitic acid content) and a fasa allele (for high stearic acid content) to obtain FI progeny. FI progeny were then selfed in subsequent generations to obtain F2 seeds and F2:3 families. F2:3 families containing maximum palmitic + stearic + oleic acid content were selected and planted and allowed to self pollinate in order to obtain F3:4 seed. A sample of F4 seed from each F3 plant (F3:4 seed) was then submitted for GC analysis so that individual F3:4 phenotypes could be determined. F3:4 plant phenotypes tracing back to a common F2 plant ancestor were then averaged to obtain mean phenotypes for F2-derived families (F2:4 family means). Single plants and family means that were highest in palmitic + stearic + oleic acid content are shown in Table 10, and are presented in order of decreasing total seed saturated fatty acids.

FI progeny were then selfed in subsequent generations to obtain F2 seeds and F2:3 families. F2:3 families containing both minimum palmitic acid content and maximum oleic acid content were then selected and planted and allowed to self pollinate in order to obtain F3:4 progenies. A sample of F4 seed from each F3 plant (F3:4 seed) was then submitted for GC analysis so that individual F3:4 phenotypes could be determined. F3:4 plant phenotypes tracing back to a common F2 plant ancestor were then averaged to obtain mean phenotypes for F2-derived families (F2:4 family means). Single plants and family means that were both lowest in palmitic acid content and highest in oleic acid content are shown in Table 11 , and are presented in order of increasing palmitic acid in total seed fatty acids. Since selection for low palmitic acid content requires precision to a tenth of a percent, palmitic values in Table 11 are shown to that level of precision while values for the other fatty acids are rounded to the nearest whole percent.

F2:3 families containing both minimum linolenic acid content and maximum oleic acid content were then selected and planted and allowed to self pollinate in order to obtain F3:4 progenies.

Total RNA was extracted and mRNA purified by oligo dT chromatography. The library was made by the technique described by Ray and Ray (1991, Nucleic Acids Research 19: 4559) using reagents purchased from Pharmacia, with some modifications. The resulting cDNA was cloned into the Lambda ZAP vector (Stratagene, La Jolla, CA) as per the manufacturer's instructions. The primary library contained approximately lxlO 6 individuals and was amplified once. Cloning techniques used were from Sambrook et al. [(1989) Molecular Cloning: A Laboratory Manual, 2 nd Edition, Cold Spring Harbor Laboratory Press]. Approximately 3x10 5 plaques from the amplified library were developed by infection of E. coli plated on a total of six plates and duplicate nitrocellulose lifts were taken from each developed plate. The duplicate nitrocellulose lifts were probed with the 32 P labeled (random primer labeling kit, Life Technologies, Gaithersburg, MD) sequence from the Brassica genomic clone (SEQ ID NO:20 in WO 92/1 1373) and annealed at 63° in hybridization buffer (6 X SSC [0.9 M NaCl, 0.09 M sodium citrate, pH 7], 5X Denhardts's solution [0.5 g Ficoll (type 400. Pharmacia), 0.5 g polyvinylpyrrolidone, 0.5 g bovine serum albumin (fraction V, Sigma), 1 mM EDTA, 1% SDS and 100 micrograms denatured salmon sperm DNA/ml (Sigma). The lifts were annealed for 18 hr, then washed at 63° in 0.2 X SSC and placed on photographic film. Sixteen plaques were scored as hybridizing to the probe, and of these seven were purified and excised according to directions in the Lambda ZAP Cloning Instruction Kit Manual (Stratagene). The resulting phagemids were used to infect E. coli XL-1 Blue cells, and resulted in double stranded plasmids containing the selected cDNA inserts. Two classes of clones were indicated by restriction analysis of the purified plasmids. One class was represented by a clone designated p5C. The insert in p5C was sequenced by dideoxy sequencing and was confirmed as encoding the Brassica napus oleoyl-ACP thioesterase. The sequence of this cDNA in shown in SEQ ID NO: 1. The sequence of the encoded protein is shown in SEQ ID NO:2. The predicted translation product is 98.6%> identical to the protein encoded by another cDNA reported by Jones et al. (1995, Plant Cell 7:359-371) and submitted to GenBank with accession number U 17098. The sequences of this second thioesterase clone and the protein are presented in SEQ ID NO:3 and 4, respectively. EXAMPLE 10 Expression of the Oleoyl-ACP Thioesterase from Brassica napus in Soybean Seeds The entire cDNA insert in p5C was released from pBluescript as an Xmn I fragment and cloned into a soybean seed expression vector for use in biolistic transformation of elite soybean cultivar A2396. A plasmid was constructed in which the acyl-ACP (oleoyl-ACP) thioesterase from Brassica napus cDNA sequence was placed under the control of the soybean beta-conglycinin promoter (Beachy R. N. et al. (1985) EMBO J. 4:3047-3053). The construction of this vector was facilitated by the use of plasmid pCW109, described in WO 94/11516. Vector pCW109 contains an 830 base DNA segment which includes the promoter sequences for the alpha subunit of the soybean seed storage protein beta conglycinin, a region with multiple restriction sites, and 1080 bases of 3' regulatory sequence from the common bean seed storage protein, phaseolin. Vector pCW109 was modified to contain a Sma I site in the multiple cloning region as well. The cDNA insert of p5C was removed by digestion with Xmn I, isolated, and ligated into the modified pCW109 which had been digested with Smal and an event in which the cDNA insert from p5C was oriented in the sense direction was chosen and designated pST14. A plasmid designated pKS 18HH was constructed to allow conferred resistance to hygromycin B to either plants or bacteria transformed with the plasmid. The plasmid was constructed using the following genetic elements: 1) plasmid vector pSP72 (Promega, Madison, WI), which was modified by removal of the β-lactamase coding region, 2) a plant selectable marker cassette consisting of the 35S promoter from cauliflower mosaic virus (CaMV) linked to the hygromycin B phosphotransferase (HPT) and the nopaline synthase 3' regulatory sequence from Agrobacterium tumefaciens, and 3) a bacterial selectable marker cassette consisting of the promoter from bacteriophage T7, a Shine-Dalgarno sequence upstream of the HPT coding sequence, and the T7 transcription terminator sequence. The hygromycin B phosphotransferase gene was obtained from E. coli strain W677 which contained a Klebsiella-derive plasmid (pJR225, Gritz, L. and Davies, J. (1983) GENE 25:179-188). The T7 promoter:HPT:T7 terminator cassette for expression of the HPT enzyme in certain strains of E. coli, such as NovaBlue (Novagen, Madison, WI) was obtained from a derivative of a pET vector. The origin of the 35S:HPT:Nopaline synthase 3' end cassette for expression of HPT in plant is described in detail WO 94/11516. One skilled in the art can incorporate these elements into a single plasmid using the usual protocols of molecular cloning. To allow use of the vector in the transformation protocol described by Christou et al. (1990, Trends Biotech 8:145) the HPT encoding sequence in the 35S:HPT:Nopaline synthase cassette was removed by restriction endonuclease digestion and replaced by the correctly oriented coding region for the bacterial β-glucuronidase gene (Jefferson et al. (1987) EMBO J. 6:3901-3907). The resulting plasmid was designated pKSl 8. The β-conglycinin:p5C:phaseolin-3' expression cassette in pST14 was removed by a partial Hindlll digestion, isolated and ligated into pKS18 that had also been digested with Hindlll to give the final transformation vector designated pRB19. The transformation technique gives plants which set seeds that may be segregating for the introduced transgene. The bulked seed from the plants may also be chimeric for the transgene. Three fertile plants were recovered from the transformation and the seeds were analyzed for their fatty acid phenotype by a partial seed analysis technique. A small chip of cotyledon oriented away from the embryonic axis was cut from the seed with a razor blade. The chip was digested in methanoi containing 1% sodium methoxide and the resulting fatty acid methyl esters were extracted into hexane prior to separation and quantification by gas liquid chromatography. Seeds with altered fatty acid profiles were thus identified for subsequent germination and growth. Of the three soybean plants transformed with the seed expression vector containing the Brassica acyl-ACP thioesterase, one had no alteration in seed fatty acid phenotype (32 seeds analyzed with a mean of 3.9% stearic acid and an observed range of 3.2% to 4.6%). The two remaining plants had an increased stearic acid content in their seeds. Twenty-nine seeds were analyzed from the second plant, and were determined to have a mean stearic acid content of 5.4% with an observed range from 3.8% to 7.5%, while forty seeds were analyzed from the third plant and were determined to have a mean stearic acid content of 4.85 and an observed range from 3.5 to 6.7%. In seeds selected from the initial transformant on the basis of elevated levels of 16:0 and 18:0, progeny were selected in subsequent generations that had consistently elevated levels of the saturated fatty acids stearic acid and palmitic acid. Stearic acid level was increased by about two- to three-fold while the palmitic acid level increased by about 25 to 40% over typical, non-transformed elite lines. The stable line that was obtained from this transformation was designated T1S. It has been deposited with the American Type Culture Collection, Manassas, VA. EXAMPLE 11 Soybean with Very High Stearic Acid Content Resulting from Combined Alterations of Stearoyl-ACP Desaturase and Oleoyl-ACP Thioesterase Crosses were made between soybean lines containing a fasa allele and soybean lines containing the T1S gene (increasing oleoyl ACP thioesterase) to obtain FI progeny. The intent is to accumulate stearoyl-ACP which is subsequently cleaved by the thioesterase resulting in the accumulation of stearic acid in the seed. F 1 progeny were then selfed in subsequent generations to obtain F2 seeds and F2:3 families. F2:3 families containing elevated levels of both palmitic and stearic acid were then selected and planted and allowed to self pollinate in order to obtain F3:4 progenies. A sample of F4 seed from each F3 plant (F3:4 seed) was then submitted for GC analysis so that individual F3:4 phenotypes could be determined. Single plant fatty acid profiles are shown in Table 13, and are presented in order of increasing total seed saturated fatty acids.

Oils were prepared from the seeds, as described in Example 1 , and analyzed for fatty acid composition and solid fat content at a variety of temperatures. Tables 14 and 15 show the compositional and functional characteristics of very high stearic soybean oils ranging from 33% to 38% stearic acid. All of the oils met the solidity requirements for a margarine (for comparison see curves in Figure 1). The SFC profiles for these high stearic oils are consistent with those obtained from stick margarines or butter (see Figure 4). It is believed that the oils derived from Example 11, as well as oils with similar compositions, will be capable of producing fat products with SFC profiles of less than 20 at 25°C, preferably less than 15 at 25°C, more preferably less than 10 at 25°C, and most preferably less than 5 at 25°C, and greater than 20 at 10°C, preferably between 20 and 50 at 10°C, and most preferably between 35 and 50 at 10°C. Therefore, these oils could be useful for producing stick margarines that are substantially free of trans fatty acids, or as a hardstock additive in blends to produce margarines or oil-based spreads.

The fatty acid profile of seed chips removed from mature cotyledons of the seed born on the transgenic plants was determined. A small fraction of the plants had seeds that appeared to be segregating for a very low saturated fatty acid phenotype. Three such plants were identified; the low saturate class for all three transgenic events averaged a combined 16:0+18:0 content of 5.6% of the total fatty acids while the normal saturated fatty acid classes averaged 14.9%. The total fatty acid profile averaged from 228 seed chips from the low saturated fatty acid class of seeds from three plants combined from the best event is given in Table 16. TABLE 16 Fattv Acid Profiles for Three Palmitoyl-ACP Thioesterase Co-Suppressed Soybean Plants Useful as One of the Parents in the Production of High Oleic and Low Saturated Fattv Acid Soybeans To produce a high oleic, low saturated fatty acid seed phenotype using the above described plants as the low saturate parent, seed remaining from the seed chip analysis is planted and taken to flowering. Reciprocal crosses are made between the palmitoyl-ACP thioesterase co-suppression plants and the fatty acid delta- 12 desaturase co-suppression plants. Since, at planting, the low saturate seed could have been from either, a seed homozygous for the transgene, or heterozygous for the transgene, remaining flowers on the parental plants are allowed to self-pollinate. The segregation pattern in the self-pollination produced seed is determined to identify plants that are homozygous for the low saturated fatty acid transgene as indicated by the absence of normal saturated fatty acid seeds. Seed from crosses, that are made to plants homozygous for the low saturated fatty acid transgene, are planted. The flowers are allowed to self pollinate and the seed, segregating for both the high oleic and low saturated fatty acid phenotypes is analyzed by the seed chip method. Remaining seed from seed chips showing the desired phenotype is planted, the plants are self-pollinated and bulked seed from individual plants is analyzed to confirm the desired phenotype.
