Description:
FIELD OF THE INVENTION 
     This invention relates to the plant enzyme ACC synthase which is essential for the production of ethylene in higher plants. More particularly, the invention relates to the DNA sequence of a Brassica oleracea ACC synthase, DNA constructs containing this sequence, plant cells containing the constructs and plants derived therefrom. 
     BACKGROUND OF THE INVENTION 
     The enzyme ACC synthase is essential to the production of ethylene in higher plants. It is well known that ethylene is related to various events in plant growth and development including fruit ripening, seed germination, abscission, and leaf and flower senescence. Ethylene production is strictly regulated by the plant and is induced by a variety of external factors known as ethylene-inducible events. These include the application of auxins, wounding, anaerobic conditions, viral infection, elicitor treatment, chilling, drought, and exposure to ions such as cadmium and lithium ions. In addition, it recently has been shown that ethylene production begins after harvest (Tian et al., J. Amer. Soc. Hort. Sci., 119:276-281 (1994)). 
     The pathway for ethylene synthesis in plants was first described by Adams and Yang, PNAS, U.S.A., 76:170-174 (1979) who identified 1-aminocyclopropane-1-carboxylic acid as an intermediate in the conversion of methionine to ethylene. The physiology and biochemistry of ethylene synthesis was extensively reviewed by Yang and Hoffman in Ann. Rev. Plant Physiol., 35:155-189 (1984). In the ethylene biosynthetic pathway, methionine is catalyzed by the enzyme S-adenosylmethionine synthetase to form S-adenosylmethionine (SAM). SAM is then converted to 1-aminocyclopropane-1-carboxylic acid (ACC) by the enzyme ACC synthase. This three-membered-ring amino acid is then metabolized to yield ethylene, a reaction catalyzed by the enzyme ACC oxidase. 
     The ethylene-forming enzyme genes in tomato were the first to be isolated. Smith et al., Planta, 168:94-100 (1986) reported the rapid appearance of an mRNA correlated with ethylene synthesis, which encodes a protein of molecular weight 35,000. This formed the basis for the development of a number of molecular strategies to inhibit ethylene formation in certain transgenic plants. One such method is based on antisense RNA. 
     As is well known, a cell manufactures protein by transcribing the DNA of the gene encoding that protein to produce RNA, which is then processed to messenger RNA (mRNA) (e.g., by the removal of introns) and finally translated by ribosomes into protein. This process may be inhibited by the presence in the cell of &#34;antisense RNA.&#34; The term antisense RNA means an RNA sequence which is complementary to a sequence of bases in the mRNA in question in the sense that each base (or the majority of bases) in the antisense sequence (read in the 3&#39; to 5&#39; sense) is capable of pairing with the corresponding base (G with C, A with U) in the mRNA sequence read in the 5&#39; to 3&#39; sense. It is believed that this inhibition takes place by formation of a complex between the two complementary strands of RNA, thus preventing the formation of protein. How this works is uncertain: the complex may interfere with further transcription, processing, transport or translation, or degrade the mRNA, or have more than one of these effects. This antisense RNA may be produced in the cell by transformation of the cell with an appropriate DNA construct arranged to transcribe the non-template strand (as opposed to the template strand) of the relevant gene (or of a DNA sequence showing substantial homology therewith). 
     The use of anti-sense RNA to downregulate the expression of specific plant genes is well known. Reduction of gene expression has led to a change in the phenotype of the plant: either at the level of gross visible phenotypic difference, e.g., lack of anthocyanin production in flower petals of petunia leading to colorless instead of colored petals (van der Krol et al., Nature, 333:866-869 (1988)); or at a more subtle biochemical level, e.g., change in the amount of polygalacturonase and reduction in depolymerization of pectin during tomato fruit ripening (Smith et al., Nature, 334:724-726 (1988)). 
     Another more recently described method of inhibiting gene expression in transgenic plants is the use of sense RNA transcribed from an exogenous template to downregulate the expression of specific plant genes (Jorgensen, Keystone Symposium &#34;Improved Crop and Plant Products through Biotechnology,&#34; Abstract X1-022 (1994)). Thus, both antisense and sense RNA have been proven to be useful in achieving downregulation of gene expression in plants. 
     SUMMARY OF THE INVENTION 
     The invention provides a DNA molecule in purified and isolated form comprising DNA encoding the ACC synthase of Brassica oleracea plant, such as broccoli, cabbage, cauliflower, brussel sprouts, kale, kohlrabi, etc. The invention also provides chimeric plant expression cassettes, i.e., constructs, comprising a DNA molecule encoding the ACC synthase of Brassica oleracea, a promoter and polyadenylation signal functional in plant cells wherein the DNA molecule encoding the ACC synthase of Brassica oleracea is operably linked to said promoter and polyadenylation signal, effective to transcribe sense and antisense RNA from the DNA encoding said ACC synthase when employed to transform the genome of a host cell, and to recombinant host cells transformed with this expression cassette. The host cells transformed with this expression cassette can include Agrobacterium tumefaciens and Agrobacterium rhizogenes cells. The invention also provides transformed B. oleracea and Cucumis melo plants and plant parts, such as seeds. The invention further provides a method to control ACC synthase production and, thus, the growth and development of Brassica oleracea and Cucumis melo plants, comprising transforming the plants with a chimeric expression cassette with a DNA molecule encoding B. oleracea ACC synthase operably linked to a promoter and polyadenylation signal functional in plants, effective to transcribe sense or antisense RNA from the DNA encoding said ACC synthase. The invention thus provides a method for controlling the maturation and aging of Brassica oleracea and Cucumis melo plants which allows one to influence, e.g., lengthen, the shelf-life of these plants and fresh vegetable products derived from these plants. 
     As used herein, with respect to a DNA molecule or &#34;gene,&#34; the phrase &#34;isolated and purified&#34; means that the molecule is either extracted from its context in the plant genome by chemical means and purified and/or modified to the extent that it can be introduced into the present cassettes in the appropriate orientation, i.e., sense or antisense. As used herein, the term &#34;chimeric&#34; refers to two or more DNA molecules which are derived from different sources, strains, or species, which do not recombine under natural conditions, or to two or more DNA molecules from the same species, which are linked in a manner that does not occur in the native genome. Thus, the present constructs and vectors permit the augmentation of plant genomes with a limited number of preselected genes. As used herein, &#34;recombinant&#34; refers to a nucleic acid molecule which has been obtained by manipulation of genetic material using restriction enzymes, ligases, and similar recombinant techniques as described by, for example, Sambrook et al., Molecular Cloning: A Laboratory Manual, Second Edition (1989) Cold Spring Harbor Laboratory Press, Cold Spring Harbor. &#34;Recombinant,&#34; as used herein, does not refer to naturally occurring genetic recombinations. As used herein, the term &#34;express&#34; or &#34;expression&#34; is defined to mean transcription alone.

     DETAILED DESCRIPTION OF THE INVENTION 
     As stated above, the present invention provides a DNA molecule that encodes the ACC synthase of Brassica oleracea plants. To practice the present invention, the ACC synthase gene must be isolated from the genome and inserted into a vector. Thus, the present invention provides an isolated and purified DNA molecule that encodes ACC synthase. As used herein, a DNA molecule that encodes ACC synthase includes nucleotides of the coding strand, also referred to as the &#34;sense&#34; strand, as well as nucleotides of the noncoding strand, complementary strand, also referred to as the &#34;antisense&#34; strand, either alone or in their base-paired configuration. Thus, a DNA molecule that encodes ACC synthase, for example, includes the DNA molecule having the nucleotide sequence of FIG. 1 [SEQ ID NO:1], a DNA molecule complementary to the nucleotide sequence of FIG. 1 [SEQ ID NO:1], as well as a DNA molecule which also encodes ACC synthase and its complement which hybridizes with an ACC synthase-specific DNA probe in hybridization buffer with 6×SSC, 5× Denhardt&#39;s reagent, 0.5% SDS and 100 μg/ml denatured, fragmented salmon sperm DNA and remains bound when washed at 68° C. in 0.1×SSC and 0.5% SDS (Sambrook et al., Molecular Cloning: A Laboratory Manual, 2nd ed. (1989)). Moreover, the DNA molecules of the present invention can include other noncoding nucleotides that do not interfere with expression of the ACC synthase gene. Preferably, the isolated and purified DNA molecules of the present invention comprise a coding region for ACC synthase. Thus, preferably the DNA molecules of the present invention are those &#34;consisting essentially of&#34; DNA that encodes ACC synthase. 
     Once a Brassica oleracea ACC synthase gene is isolated and amplified, a ACC synthase fragment can be produced in a variety of recombinant systems. The gene is placed into an expression vector which can be transformed into plant cells. This can then be used in a method of inhibiting ethylene inducible events in a plant. Specifically, the method involves: providing a transgenic plant stably transformed with an exogenous chimeric DNA construct comprising DNA of Brassica oleracea ACC synthase placed in an orientation relative to a promoter in the chimeric DNA construct so that antisense RNA is transcribed; and culturing said transgenic plant under conditions so that said DNA is transcribed to antisense RNA. Alternatively, the method involves: providing a transgenic plant stably transformed with an exogenous chimeric DNA construct comprising DNA of Brassica oleracea ACC synthase placed in an orientation relative to a promoter in the chimeric DNA construct so that sense RNA is transcribed; and culturing said transgenic plant under conditions so that said DNA is transcribed to sense RNA. 
     The ACC synthase gene does not contain the signals necessary for its expression once transferred and integrated into a plant genome. Accordingly, a vector must be constructed to provide the regulatory sequences such that they will be functional upon inserting a desired gene. When the expression vector/insert construct is assembled, it is used to transform plant cells which are then used to regenerate plants. These transgenic plants carry the viral gene in the expression vector/insert construct. The gene is expressed in the plant. 
     Plants harboring an expression vector can be assayed to determine whether the transgenic plants produce elevated levels of sense or antisense RNA and if aspects of plant development which are ethylene sensitive have been affected, and in particular, if plant senescence has been delayed. Plants stably transformed with expression vectors containing either genomic- or cDNA-derived ACC synthase sequences can be assayed for expression of recombinant ACC synthase sequences and/or for ACC synthase levels in said plants by methods well known in the art. 
     Using methods well known in the art, a quantity of Brassica oleracea genomic DNA is isolated. Polymerase chain reactions can be used to amplify the DNA encoding the ACC synthase gene with the use of oligomer primers specific for the ACC synthase gene. These primers can include novel restriction sites used in subsequent cloning steps. PCR amplified fragments are inserted into cloning vectors, such as well-characterized plasmids, which are then used to transform E. coli and create a DNA library. 
     To isolate a cDNA clone of a ACC synthase of Brassica oleracea, Brassica oleracea polyA+ RNA is isolated, and a cDNA library is created using the RNA, by methods known to the art. The RNA is incubated with primers that hybridize to the RNA and reverse transcriptase, and a complementary DNA molecule is produced. A DNA complement of the complementary DNA molecule is produced and that sequence represents a DNA copy (cDNA) of the original RNA molecule. The DNA complement can be produced in a manner that results in a single double stranded cDNA or polymerase chain reactions can be used to amplify the DNA encoding the cDNA with the use of oligomer primers specific for the ACC synthase gene. These primers can include novel restriction sites used in subsequent cloning steps. Thus, a double stranded DNA molecule is generated which contains the sequence information of the ACC synthase RNA. The double stranded DNA molecules are inserted into cloning vectors, such as well-characterized plasmids, which are then used to transform E. coli and create a cDNA library. 
     Previously identified ACC synthase genes can be used as hybridization probes to screen the library to determine if any of the transformed bacteria contain DNA fragments with sequences coding for the ACC synthase. Alternatively, plasmids can be screened by restriction enzyme digests to determine if the desired sequences are present. The inserts in any bacterial colonies which contain this region can be sequenced. 
     Because neither genomic or cDNA clones contain transcription and translation signals necessary for expression once transferred and integrated into a plant genome, they must, therefore, be engineered to contain a plant expressible promoter, a translation initiation codon (ATG), and a plant functional poly(A) addition signal (AATAAA) 3&#39; of its translation termination codon. Thus, for expression in plants, the chimeric expression cassette will contain in addition to the ACC synthase-encoding DNA sequence, a plant promoter region, a transcription initiation site (if the coding sequence to be transcribed lacks one), and a transcription termination sequence. Unique restriction enzyme sites at the 5&#39; and 3&#39; ends of the cassette are typically included to allow for easy insertion into a pre-existing construct, such as a plasmid or phage. 
     Any of a number of transcription initiation regions (i.e., promoters) that direct transcription in plant cells is suitable. The promoter can be either constitutive or inducible. It can be of bacterial origin, viral origin, or eukaryotic origin, such as plant origin. 
     Promoters of bacterial origin include the octopine synthase promoter, the nopaline synthase promoter and other promoters derived from native Ti plasmids (Herrera-Estrella et al., Nature, 303:209-213 (1983)). The nopaline synthase (Nos) promoter has been shown to be active in at least the following monocot and dicot plants with edible parts: apple, Malus pumila; cauliflower, Brassica oleracea; celery, Apium graveolens; cucumber, Cucumis sativus; eggplant, Solanum melongena; lettuce, Lactuca sativa; potato, Solanum tuberosum; rye, Secale cereale; strawberry, Fragaria xananassa; tomato, Lycopersicon esculentum; and walnut, Juglans regia. 
     Viral promoters include the 35S and 19S RNA promoters of cauliflower mosaic virus (O&#39;Dell et al., Nature, 313:810-812 (1985)). The cauliflower mosaic virus (CaMV) 35S promoter has been shown to be highly active in many plant organs and during many stages of development when integrated into the genome of transgenic plants including tobacco and petunia, and has been shown to confer expression of foreign genes in protoplasts of both dicots and monocots. For example, the CaMV 35S promoter has been demonstrated to be active in at least the following monocot and dicot plants with edible parts: blackberry, Rubus; blackberry/raspberry hybrid, Rubus, and red raspberry; carrot, Daucus carota; maize; potato, Solanum tuberosum; rice, Oryza sativa; strawberry, Fragaria xananassa; and tomato, Lycopersicon esculentum. 
     In addition, plant promoters such as ribulose-1,3-diphosphate carboxylase, flower organ-specific promoters, heat shock promoters, seed-specific promoters, promoters that are transcriptionally active in associated vegetable tissue, etc. can also be used. Organ-specific promoters are also well known. For example, the E8 promoter is only transcriptionally activated during tomato fruit ripening, and can be used to target gene expression in ripening tomato fruit (Deikman and Fischer, EMBO J., 7:3315 (1988)). The activity of the E8 promoter is not limited to tomato fruit, but is thought to be compatible with any system wherein ethylene activates biological processes. Other organ-specific promoters appropriate for a desired target organ can be isolated using known procedures. These control sequences are generally associated with genes uniquely expressed in the desired organ. In a typical higher plant, each organ has thousands of mRNAs that are absent from other organ systems (reviewed in Goldberg, Trans. R. Soc. London, B314:343 (1986)). 
     DNA sequences controlling eukaryotic gene expression have been extensively studied. Promoter sequence elements include the TATA box consensus sequence (TATAAT), which is usually 20-30 base pairs (bp) upstream of the transcription start site. In most instances, the TATA box is required for accurate transcription initiation. By convention, the start site is called +1. Sequences extending in the 5&#39; (upstream) direction are given negative numbers and sequences extending in the 3&#39; (downstream) direction are given positive numbers. In plants, further upstream from the TATA box, at positions -80 to -100, there is typically a promoter element with a series of adenines surrounding the trinucleotide G (or T)NG (Messing, J. et al., in Genetic Engineering in Plants, Kosage, Meredith and Hollaender, eds. (1983) pp. 221-227). Other sequences conferring tissue specificity, response to environmental signals, or maximum efficiency of transcription may also be found in the promoter region. Such sequences are often found within 400 bp of transcription initiation site, but may extend as far as 2000 bp or more. 
     In the construction of chimeric promoter/structural gene cassettes, the promoter is preferably positioned about the same distance from the heterologous transcription start site as it is from the transcription start site in its natural setting. As is known in the art, however, some variation in this distance can be accommodated without loss of promoter function. 
     In addition to a promoter sequence, the expression cassette should also contain a transcription termination region downstream of the gene to provide for efficient termination. The termination region may be obtained from the same gene as the promoter sequence or may be obtained from different genes. 
     If the mRNA transcribed from the gene is to be efficiently processed, DNA sequences which direct polyadenylation of the RNA are also commonly added to the vector construct (Albert and Kawaski, Mol. and Appl. Genet., 1:419-434 (1982)). Polyadenylation is of importance for expression of the ACC synthase-encoding RNA in plant cells. Polyadenylation sequences include, but are not limited to, the Agrobacterium octopine synthase signal (Gielen et al., EMBO J., 3:835-846 (1984)), and the nopaline synthase signal (Depicker et al., Mol. and Appl. Genet., 1:561-573 (1982)). Replication sequences, of bacterial or viral origin, are generally also included to allow the cassette to be cloned in a bacterial or phage host. 
     Selectable marker genes can be incorporated into the present expression cassettes and used to select for those cells or plants which have become transformed. The marker gene employed may express resistance to an antibiotic, such as kanamycin, gentamycin, G418, hygromycin, streptomycin, spectinomycin, tetracyline, chloramphenicol, and the like. Other markers could be employed in addition to or in the alternative, such as, for example, a gene coding for herbicide tolerance such as tolerance to glyphosate, sulfonylurea, phosphinothricin, or bromoxynil. Additional means of selection could include resistance to methotrexate, heavy metals, complementation providing prototrophy to an auxotrophic host, and the like. 
     The particular marker employed will be one which will allow for the selection of transformed cells as opposed to those cells which are not transformed. Depending on the number of different host species one or more markers can be employed, where different conditions of selection would be useful to select the different host, and would be known to those of skill in the art. A screenable marker such as the β-glucuronidase gene can be used in place of, or with, a selectable marker. Cells transformed with this gene can be identified by the production of a blue product on treatment with 5-bromo-4-chloro-3-indoyl-β-D-glucuronide (X-Gluc). 
     In developing the present expression construct, i.e., expression cassette, the various components of the expression construct such as the DNA molecules, linkers, or fragments thereof will normally be inserted into a convenient cloning vector, such as a plasmid or phage, which is capable of replication in a bacterial host, such as E. coli. Numerous cloning vectors exist that have been described in the literature. After each cloning, the cloning vector can be isolated and subjected to further manipulation, such as restriction, insertion of new fragments, ligation, deletion, resection, insertion, in vitro mutagenesis, addition of polylinker fragments, and the like, in order to provide a vector which will meet a particular need. 
     A number of techniques are available for transformation of plants or plant cells. All types of plants are appropriate subjects for &#34;direct&#34; transformation. Most dicot species can be transformed in vitro by Agrobacterium as well as species which are a natural plant host for Agrobacterium. Monocotyledonous plants, and in particular, cereals, are not natural hosts to Agrobacterium. Attempts to transform them using Agrobacterium have been unsuccessful until recently (Hooykas-Van Slogteren et al., Nature (1984) 311:763-764). However, there is growing evidence now that certain monocots can be transformed by Agrobacterium. 
     In one form of direct transformation, the cassette is microinjected directly into plant cells by use of micropippettes to mechanically transfer the recombinant DNA (Crossway, Mol. Gen. Genetics, 202:179-185 (1985)). In another form, the genetic material is transferred into the plant cell using polyethylene glycol (Krens, et al., Nature, 296:72-74 (1982)). In yet another form of direct transformation, the genetic material is transferred using high velocity ballistic penetration by small particles with the nucleic acid either within the matrix of small beads or particles, or on the surface (Klein, et al., Nature, 327:70-73 (1987)). In still another method, protoplasts are fused with other entities which contain the DNA whose introduction is desired. These entities are minicells, cells, lysosomes or other fusible lipid-surfaced bodies (Fraley, et al., Proc. Natl. Acad. Sci. U.S.A., 79:1859-1863 (1982)). DNA may also be introduced into the plant cells by electroporation (Fromm et al., Proc. Natl. Acad. Sci. U.S.A., 82:824 (1985)). In this technique, plant protoplasts are electroporated in the presence of plasmids containing the expression cassette. Electrical impulses of high field strength reversibly permeabilize biomembranes allowing the introduction of the plasmids. Electroporated plant protoplasts reform the cell wall, divide and regenerate. 
     For transformation mediated by bacterial infection, a plant cell is infected with Agrobacterium tumefaciens or Agrobacterium rhizogenes previously transformed with the DNA to be introduced. Agrobacterium is a representative genus of the gram-negative family Rhizobiaceae. Its species are responsible for crown gall (A. tumefaciens) and hair root disease (A. rhizogenes). The plant cells in crown gall tumors and hairy roots are induced to produce amino acid derivatives known as opines, which are catabolized only by the bacteria. The bacterial genes responsible for expression of opines are a convenient source of control elements for chimeric expression cassettes. In addition, assaying for the presence of opines can be used to identify transformed tissue. 
     Heterologous genetic sequences can be introduced into appropriate plant cells, by means of the Ti plasmid of A. tumefaciens or the Ri plasmid of A. rhizogenes. The Ti or Ri plasmid is transmitted to plant cells on infection by Agrobacterium and is stably integrated into the plant genome (Schell, J., Science, 237:1176-1183 (1987)). Ti and Ri plasmids contain two regions essential for the production of transformed cells. One of these, named transferred DNA (T-DNA), is transferred to plant nuclei and induces tumor or root formation. The other, termed the virulence (vir) region, is essential for the transfer of the T-DNA but is not itself transferred. The T-DNA will be transferred into a plant cell even if the vir region is on a different plasmid (Hoekema, et al., Nature, 303:179-189 (1983)). The transferred DNA region can be increased in size by the insertion of heterologous DNA without its ability to be transferred being affected. Thus a modified Ti or Ri plasmid, in which the disease-causing genes have been deleted, can be used as a vector for the transfer of the gene constructs of this invention into an appropriate plant cell. Construction of recombinant Ti and Ri plasmids in general follows methods typically used to introduce additional DNA into the more common bacterial vectors, such as pBR322. Additional use can be made of accessory genetic elements sometimes found with the native plasmids and sometimes constructed from foreign sequences. These may include, but are not limited to, &#34;shuttle vectors&#34; (Ruvkum and Ausubel, Nature, 298:85-88 (1981)), promoters (Lawton et al., Plant Mol. Biol., 9:315-324 (1987)), and structural genes for antibiotic resistance as a selection factor (Fraley et al., Proc. Natl. Acad. Sci., 80:4803-4807 (1983)). 
     There are two classes of recombinant Ti and Ri plasmid vector systems now in use. In one class, called &#34;cointegrate,&#34; the shuttle vector containing the gene of interest is inserted by genetic recombination into a non-oncogenic Ti plasmid that contains both the cis-acting and trans-acting elements required for plant transformation as, for example, in the PMLJ1 shuttle vector of DeBlock et al., EMBO J., 3:1681-1689 (1984) and the non-oncogenic Ti plasmid pGV2850 described by Zambryski et al., EMBO J., 2:2143-2150 (1983). In the second class or &#34;binary&#34; system, the gene of interest is inserted into a shuttle vector containing the cis-acting elements required for plant transformation. The other necessary functions are provided in trans by the non-oncogenic Ti plasmid as exemplified by the pBIN19 shuttle vector described by Bevan, Nucleic Acids Research, 12:8711-8721 (1984), and the non-oncogenic Ti plasmid PAL4404 described by Hoekema, et al., Nature, 303:179-180 (1983). Some of these vectors are commercially available. 
     There are two common ways to transform plant cells with Agrobacterium: co-cultivation of Agrobacterium with cultured isolated protoplasts, or transformation of intact cells or tissues with Agrobacterium. The first requires an established culture system that allows for culturing protoplasts and subsequent plant regeneration from cultured protoplasts. The second method requires (a) that the intact plant tissues, such as cotyledons, can be transformed by Agrobacterium and (b) that the transformed cells or tissues can be induced to regenerate into whole plants. 
     Plant cells that have been transformed can also be regenerated using known techniques. Plant regeneration from cultured protoplasts is described in Evans et al., Handbook of Plant Cell Cultures, Vol. 1:MacMillan Publishing Co. New York, 1983; and Vasil I. R. (ed.), Cell Culture and Somatic Cell Genetics of Plants, Acad. Press, Orlando, Vol. I, 1984, and Vol. II, 1986. It is known that practically all plants can be regenerated from cultured cells or tissues, including but not limited to, all major species of sugar cane, sugar beet, corn, cotton, fruit trees, and legumes. The regenerated plants are transferred to soil and cultivated in a conventional manner. 
     A large number of plants have been shown capable of regeneration from transformed individual cells to obtain transgenic whole plants. For example, regeneration has been shown for dicots as follows: apple, Malus pumila; blackberry, Rubus; Blackberry/raspberry hybrid, Rubus; red raspberry, Rubus; carrot, Daucus carota; cauliflower, Brassica oleracea; celery, Apium graveolens; cucumber, Cucumis sativus; eggplant, Solanum melongena; lettuce, Lactuca sativa; potato, Solanum tuberosum; rape, Brassica napus; soybean (wild), Glycine canescens; strawberry, Fragaria xananassa; tomato, Lycopersicon esculentum; walnut, Juglans regia; melon, Cucumis melo; grape, Vitis vinifera; mango, Mangifera indica; and for the following monocots: rice, Oryza sativa; rye, Secale cereale; and maize. 
     In addition, regeneration of whole plants from cells (not necessarily transformed) has been observed in: apricot, Prunus armeniaca; asparagus, Asparagus officinalis; banana, hybrid Musa; bean, Phaseolus vulgaris; cherry, hybrid Prunus; grape, Vitis vinifera; mango, Mangifera indica; melon, Cucumis melo; okra, Abelmoschus esculentus; onion, hybrid Allium; orange, Citrus sinensis; papaya, Carrica papaya; peach, Prunus persica and plum, Prunus domestica; pear, Pyrus communis; pineapple, Ananas comosus; watermelon, Citrullus vulgaris; and wheat, Triticuim aestivum. 
     Means for regeneration vary from species to species of plants, but generally a suspension of transformed protoplasts or a petri plate containing transformed explants is first provided. Callus tissue is formed and shoots may be induced from callus and subsequently rooted. Alternatively, somatic embryo formation can be induced in the callus tissue. These somatic embryos germinate as natural embryos to form plants. The culture media will generally contain various amino acids and plant hormones, such as auxin and cytokinins. It is also advantageous to add glutamic acid and proline to the medium, especially for such species as corn and alfalfa. Efficient regeneration will depend on the medium, on the genotype, and on the history of the culture. If these three variables are controlled, then regeneration is usually reproducible and repeatable. 
     After the expression cassette is stably incorporated into regenerated transgenic plants, it can be transferred to other plants by sexual crossing. Any of a number of standard breeding techniques can be used, depending upon the species to be crossed. The plants are grown and harvested using conventional procedures.

     EXAMPLE 1 
     A. Extraction of Total Cellular DNA From Broccoli by a CTAB Extraction Method 
     Three or four newly expanding leaves of broccoli (0.5-1 gm fresh weight) were placed into the bottom corner of a ZIPLOC brand bag. One mL of preheated CTAB extraction buffer was added to the leaf sample. CTAB extraction buffer (1% (w/v) CTAB Sigma H-5882; 1.4 M NaCl; 100 mM Tris HCl pH 8.0; 30 mM EDTA pH 8.0) was prepared and preheated to 65° C. 5-10 minutes prior to use. The following was added to each mL of CTAB extraction buffer just before using: 10 μL of 2-mercaptoethanol, 6 μL of Ribonuclease T 1  (5,000 U/ml) Sigma R-8251, and 25 μL of Ribonuclease A (10 mg/ml) Sigma R-4875. 
     The ZIPLOC brand bag was placed flat on a hard surface. A one-liter Corning media-bottle was firmly rolled across the surface of the bag repeatedly until the leaf tissue was disrupted and had the consistency of applesauce. The macerated sample was moved to a bottom corner of the ZIPLOC brand bag and the corner was cut with a scissors. The entire sample was squeezed into a sterile 15-mL Falcon tube and incubated at 70° C. for 30 minutes. The sample was cooled for 5 minutes at room temperature. One mL of chloroform-octanol (24:1, v/v) was added, and the sample was vortexed for 1 second to mix thoroughly. The samples were then centrifuged in a Beckman GH 3.7 rotor (Beckman GPR centrifuge) at 2500 rpm, 25° C. for 5 minutes to separate phases. The aqueous phase (approximately 1000 μl) was then transferred to a sterile 1.5-mL Eppendorf tube and 1.5 μL of RNAse T 1  (10 mg/mL) was added. An equal volume of 1% CTAB precipitation buffer was added to each sample. The tube was inverted a few times and incubated at room temperature for 30 minutes. 
     The sample was centrifuged in an Eppendorf microfuge for 60 seconds to pelletize the precipitate. The supernatant was discarded, and the tube was inverted on a paper towel to drain. Following this, 500 μL of a high salt solution (10 mM Tris pH 8.0, 1 M Nal, 1 mM EDTA pH 8.0) was added, and the sample was incubated at 65° C. for 15 minutes to dissolve the DNA. One mL of 100% ethanol was added and the sample was placed at -20° C. for one hour, or overnight if desired, to precipitate DNA. DNA was hooked or spooled with a 1.5-mL capillary pipet and placed into a sterile 1.5-mL Eppendorf tube. The DNA pellet was washed by adding 1 mL of wash solution (80% ethanol, 15 mM ammonium acetate) and incubated at room temperature for 15 minutes. The washed DNA was dissolved in 300 μL of sterile water. 
     B. PCR Amplification of Target Genomic ACC Synthase 
     Polymerase chain reactions (PCRs) were carried out using reagents supplied with the Perkin Elmer Cetus Gene Amp PCR Kit under the following conditions: approximately 0.1 μg/mL total cellular DNA of Brassica oleracea, 1.5 mM MgCl.sub., 24 μg/mL of each oligomer primer, 200 μM each DNTP, kit reaction buffer, and AmpliTaq DNA polymerase supplied with the kit. Reaction tubes were subjected to 93C. for 1 minute, 55C. for 1 minute, then 72C. for 3 minutes for 30 cycles in a Perkin Elmer Thermocycler. Oligonucleotides used to prime the PCR were modeled after sequences of a cDNA clone of the ACC synthase gene found in Arabidopsis thaliana (Van der Straten et al., Proc. Nat&#39;l. Acad. Sci U.S.A., 89:9969-9973 (1992)). Oligomer primers RMM393 (5&#39;-CCATGGGATCATCCAAATGGGTCTTGCAGAG-3&#39; [SEQ ID NO:3], which is complementary to the 5&#39; end of the cDNA clone of Arabidopsis thaliana ACC synthase gene) and RMM394 (5&#39; -CCTACCAAATCCTAAACGAAACGGTGGTACC-3&#39; [SEQ ID NO:4], which is complementary to the 3&#39; end of the cDNA clone of Arabidopsis thaliana ACC synthase gene), were used to prime this reaction (FIG. 1). 
     C. Cloning Genomic ACC Synthase PCR Fragment into the pCRII Vector 
     The genomic ACC synthase PCR DNA fragment was cloned into the pCRII vector supplied with the TA Cloning Kit, purchased from Invitrogen Corporation, San Diego, Calif., to obtain a clone known as ACCA1 (FIG. 2). The sequence of the inserted gene in ACCA1 was determined by nucleotide DNA sequencing using a U.S. Biochemical (Cleveland, Ohio) dideoxy sequencing kit (FIG. 1) [SEQ ID NO:1]. In an effort to determine the intron/exon structure of the genomic ACC synthase DNA sequence, the deduced amino acid sequence of the Brassica oleracea genomic clone ACCA1 was compared with the published amino acid sequence of Arabidopsis thaliana ACC synthase. Three complete exons and two introns were identified in genomic clone ACCA1. 
     A Brassica juncea ACC synthase cDNA clone published by Wen et al., Plant Physiol., 103:1019-1020 (1993) was compared to the Brassica oleracea genomic clone ACCA1 (FIG. 1). The relatedness of conserved portions of these two sequences showed that the ACCA1 clone encoded an ACC synthase. The structure of Brassica oleracea ACC synthase is highly related to the intron/exon arrangement in the tomato genomic ACC synthase clone GTOMA (Holdsworth et. al., Nuc. Acids Res., 15:10600 (1987)). 
     D. Insertion of the ACC Synthase Coding Sequence into an Expression Cassette (cp Express) 
     To begin transfer of the genomic Brassica oleracea ACC synthase gene into a plant expression cassette, ACCA1 was digested with NcoI to produce a 1380 bp NcoI fragment encoding genomic Brassica oleracea ACC synthase. Using standard methods (see Slightom, Gene, 100:251-255 (1991)), this fragment was inserted into the expression cassette pUC18cp in an antisense orientation to obtain ACCA1CP8 and in the sense orientation to obtain ACCA1CP16 (FIG. 2). 
     E. Insertion of Genomic ACC Synthase DNA Cassettes into a Binary Vector 
     HindIII fragments harboring the full-length cDNA clone inserted in the antisense and sense cassettes were isolated. The antisense cassette ACCA1CP8 (FIG. 2) was inserted into the unique HindIII site of binary vector pGA482G to produce plasmid pEPG610 (FIG. 3, for further information regarding pGA482G, see Applicants&#39; Assignees copending patent application Ser. No. 08/366,991, entitled &#34;Transgenic Plants Expressing DNA Constructs Containing a Plurality of Genes to Impart Virus Resistance&#34; filed on Dec. 30, 1994, incorporated by reference herein). The sense cassette ACCA1CP16 (FIG. 2) was inserted into the unique HindIII site of binary vector pGA482G to produce plasmid pEPG611 (FIG. 3). The structures shown in FIG. 3 were verified by restriction analysis. 
     F. Transformation of the Binary Vectors into Brassica oleracea Plants by Agrobacteria-Mediated Transformation 
     The binary plasmids pEPG610 and pEPG611 are transformed into strains of Agrobacterium tumefaciens, e.g., strain C58Z707 and Agrobacterium rhizogenes, e.g., strain A4RC in preparation for Brassica oleracea transformation procedures. Strain C58Z707 was obtained from Augus Hepburn at Indiana University, Bloomington, Ind. (Hepburn et al., J. Gen. Micro., 131:2961-2969 (1985)). Strain A 4  RC was obtained from Jerry Slightom, The Upjohn Company, Kalamazoo, Mich. Evidence of the origin of the strain A 4  is presented by Slightom et al., J. Biol. Chem., 261(1):108-121 (1986). The resulting Acrobacterium strain is used to perform Brassica oleracea plant transformation procedures. Agrobacterium-mediated transfer of the plant expressible Brassica oleracea ACC synthase is done using procedures known to those skilled in the art (For example see David et al., Plant Cell Reports, 7:88-91 (1988) and Damgaard et al., Plant Molecular Biology, 17:1-8 (1991)). Specifically, aseptically grown hypocotyls with or without an intact root system are inoculated with engineered A. tumefaciens or A. rhizogenes. Hypocotyls are then transferred to MS medium (Murashige et al., Physiol Plantarum, 15:473-497 (1962)) containing 200 micromolar acetosyringone. Two to three days later, hypocotyls are transferred to MS medium containing 50 mg/L kanamycin sulfate, 500 mg/L carbenicillin and 200 mg/L cefotaxime (MS-O). Hypocotyls are continuously subcultured every 21 days on MS-O medium until shoots form. Shoots are then removed from agar and potted in soil. Transgenic plants (R 0 ) are grown to sexual maturity in a greenhouse and R 1  transgenic seed is produced. 
     G. Evaluation of Transgenic Plants for Inhibition of Ethylene Biosynthesis 
     The transformation of R 0  plants and their segregating progeny is verified by routine methods. These include ELISA assays for NPTII protein detection and DNA assays such as PCR amplification (detection) and Southern blot hybridization for detection of the foreign DNA. 
     For example, protein in leaf tissue samples taken from R 1  transgenic broccoli seedlings is extracted and analyzed for NPTII protein by enzyme-linked immunosorbant assay (ELISA). The procedure and kit supplied by 5 Prime→3 Prime, Inc., Boulder, Colo., is used to assay NPTII expression in R 1  transgenic broccoli seedlings. In an initial screen of R 1  transgenic seedlings for NPTII protein by ELISA, all independent transgenic proprietary Brassica oleracea lines express NPTII. The data indicate that these initial lines are segregating for the NPTII marker gene. 
     Evaluation of transgenic plants for inhibition of ethylene biosynthesis can be accomplished by assaying transgenic Brassica oleracea materials for expression of ACC synthase sense or antisense RNA using Northern blotting or a RNase protection assay. In a Northern blot of transgenic materials, RNA extracted from transgenic Brassica oleracea is subjected to agarose electrophoresis and blotted onto a Nylon membrane. Radioactive  32  P-labelled antisense RNA or  32  P-labelled sense RNA probes were synthesized in vitro and used to hybridize the blot. Only antisense RNA of the ACC synthase transgene in the plant will bind to the  32  P-labelled sense RNA probe; thus antisense ACC synthase RNA will be detected by autoradiography. Parallel hybridization of replicate blots with antisense ACC synthase RNA probe serves as a check on the hybridization with the sense RNA probe. Likewise, only sense RNA of the ACC synthase transgene in the plant will bind to the  32  P-labelled antisense RNA probe; thus sense ACC synthase RNA will be detected by autoradiography. Parallel hybridization of replicate blots with sense ACC synthase RNA probe serves as a check on the hybridization with the antisense RNA probe. 
     The RNase protection assay involves hybridizing a labelled RNA molecule (pure sequence synthesized in vitro) with total tissue RNA in solution in a tube. Only complementary RNA will hybridize with the pure RNA labelled and synthesized in vitro. The total pool of RNA is subjected to RNase A and RNase T 1  digestion; protected mRNAs are resistant to RNase digestion. Protected mRNAs are evaluated quantitatively and qualitatively on an acrylamide gel. 
     Following the determination of whether Brassica oleracea ACC synthase antisense or sense RNA is expressed, the transgenic materials or tissues are assayed for ACC synthase activity. The biochemical detection of ACC synthase can be performed as described by Sato et al., J. Biol. Chem., 266:3752-3759 (1991). The enzyme sample is incubated with 200 μM AdoMet (S-adenosylmethionine), 10 μM pyridoxal phosphate, 40 μg BSA (bovine serum albumin) in 200 mM Hepes buffer pH 8.5, in a total volume of 600 μL in a 12×75 mm test tube at 30° C. for 30 minutes. The amount of ACC formed is assayed according to Lisada et al., Anal. Biochem., 100:140-150 (1979). The protein concentration is determined according to Bradford, Anal. Biochem., 72:248-254 (1976) using bovine gamma-globulin IgG as a standard. Hall et al. (Plant Growth Regulation, 13:225-230 (1993)) report an alternative method of measuring ACC levels in plant materials. Very briefly, the method involves the following steps: 1) homogenization of plant materials in appropriate extraction medium containing 80% (v/v) methanol and butylated hydroxytoluene (as an antioxidant); 2) addition of  14  C ACC to the extracts; 3) preliminary purification using a small, strongly acidic, ion exchange column (Bondelute SCX 3CC); 4) esterification with acidified n-propanol, and benzoylation with benzoic anhydride in pyridine at 110° C.; 5) pyridine evaporation, followed by HPLC purification; and 6) measurement for recovery by radioactive scintillation counting. 
     In addition, it is possible to employ immunological methods (for example, ELISA or Western blots) to assay transgenic materials for levels of ACC synthase protein. It is expected that transgenic materials would exhibit reduced levels of ACC synthase protein compared with non-transgenic materials. Tian et al., J. Amer. Soc. Hort. Sci., 119:276-281 (1994) outline in some detail their procedures for evaluating &#34;degreening&#34; in response to ethylene in harvested broccoli. They measured chlorophyll content in the florets after harvest. 
     H. Brassica oleracea ACC Synthase cDNA Gene Constructions 
     cDNA fragments of ACC synthase were obtained by PCR amplification of ACC fragments from total cDNA. Briefly, the process involved the following steps: 1) isolation of total RNA from broccoli heads (florets); 2) enrichment for polyA+ RNA; 3) synthesis of single-stranded cDNA; 4) polymerase chain reaction amplification of target ACC synthase sequences; 5) cloning an ACC synthase PCR fragment into the PCRII vector; 6) insertion of the ACC synthase coding sequence into an expression cassette (cp express) in sense or antisense orientation; 7) insertion of an ACC synthase cassette into a binary vector; 8) transformation of the binary vector into Agrobacterium; 9) transfer of the construct into Brassica oleracea plants by Agrobacteria-mediated transformation; and 10) evaluation of transgenic plants for inhibition of ethylene biosynthesis. 
     First, total RNA was isolated from broccoli florets (heads) by the use of Tri-Reagent and the instructions provided with the reagent (Molecular Research Center, Inc). Second, polyA+ RNA was enriched by oligo dT cellulose chromatography. Briefly, the procedure involves mixing total broccoli floret RNA (this includes messenger RNA or polyA+ RNA) with oligo dT-cellulose in 20 mM NaCl and Tris buffer. The oligo-dT cellulose is washed to eliminate non-polyadenylated RNAs from the cellulose. Subsequently, RNA enriched for polyA+ RNA is eluted from the cellulose by elution in Tris buffer that includes no NaCl. 
     Third, single-stranded cDNA was synthesized using polyA+ RNA template. The reaction included 1×First Strand cDNA Synthesis Buffer (GIBCO-BRL), 1 mM dNTP&#39;s (USB), 1 μg oligo dT, 1 μL RNasin (Promega), 3.3 uM dithiothreitol, 5 μL  32  PdCTP (3000 Ci-mmol, NENDuPont NEGo13H), and 1 μL RTase Superscript (GIBCO-BRL). Single-stranded B. oleracea cDNA was purified by the use of columns (Quiaquick-spin PCR column) obtained from Qiagen. The first strand cDNA reaction was characterized by hydroxide agarose gel electrophoresis; based on electrophoretic mobility it was estimated that the size distribution of first strand cDNA centered near 1 kilobase. 
     Fourth, an ACC synthase cDNA fragment (approximately 1 kb in length) was PCR amplified with the use of the cDNA template obtained as above. The polymerase chain reaction (PCR) was carried out using reagents supplied with the Perkin Elmer Cetus Gene Amp PCR Kit under the following conditions: ˜50 ng (estimated) total cDNA of Brassica oleracea, 2.0 mM MgCl 2 , 12 μg/mL of each oligomer primer, 800 μM each dNTP, kit reaction buffer, and AmpliTaq DNA polymerase supplied with the kit. Reaction mixtures were first subjected to 98° C. for 1 minute, then 93° C. for 45 seconds, 55° C. for 45 seconds, and 72° C. for 1.5 minutes for five cycles, then 93° C. for 45 seconds, 52° C. for 45 seconds, and 72° C. for 1.5 minutes for 33 cycles, and finally 72° C. for five minutes in a Perkin Elmer Thermocycler. Oligomer primers RMM491 and RMM494 were used to prime this reaction (FIG. 4). 
     The reaction yielded a 1-kb fragment which was subsequently gel-purified and cloned into the cloning vector PCRII (Invitrogen Corporation) by methods well known to those skilled in the art. By restriction analysis two ACC synthase cDNA clone candidates were identified. Nucleotide sequence analysis of clone ACCcDNA TA13 confirmed that the insert encodes ACC synthase (FIG. 5). The ACC synthase cDNA sequences from clone ACCcDNA TA13 are then placed into pUC18cpexpress for antisense RNA or for sense RNA expression in transgenic plants. 
     Melons were made transgenic for B. oleracea ACC oxidase and ACC synthase antisense constructs to inhibit ethylene production in climacteric fruit and extend shelf-life. Brassica oleracea ACC synthase antisense constructs were transferred to melon (Cucumis melo) plants via Agrobacteria-mediated transformation using procedures published by Fang and Grumet (1990 and 1993). The following constructs were transformed into melon: pEPG610 and pEPG612. 
     After shoots were regenerated on kanamycin-containing solid tissue culture media, they were rooted and tested for transformation status. Transformation status was verified either by testing regenerated organized shoots for ability to form callus on kanamycin-containing solid media (only transformed materials expressing NPTII can grow on this media) or by NPTII expression detected by ELISA. 
     Inbred cantaloupe line 10 was used to produce 29 experimental transgenic plant lines containing the pEPG610 plasmid contract, 27 of which are viable potted plants. Inbred cantaloupe line CA96 was used to produce 32 experimental transgenic plant lines containing the pEPG612 plasmid construct, all of which are viable potted plants. Inbred cantaloupe line 1077 was used to produce 7 experimental transgenic plant lines, containing the pEPG612 plasmid construct, all of which are viable potted plants. 
     The complete disclosures of all patents, patent documents, and publications are incorporated herein by reference, as if individually incorporated by reference. While specific embodiments of the invention have been described, it should be apparent to those skilled in the art that various modifications thereof can be made without departing from the true spirit and scope of the invention. Accordingly, it is intended that the following claims cover all such modifications within the full inventive concept. 
     In addition to the transgenic melons obtained with the use of ACC synthase constructs (eg., pEPG610 and 612), transgenic red cabbage plants are also being produced with the use of ACC synthase constructs.

Currently, shoots are being recovered from transformation procedures; these will be rooted shortly and evaluated for ACC synthase RNA production.
