This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/869,290, filed Dec. 8, 2006.
The present invention relates to plant genes involved in nitrate uptake and metabolism.
Nitrogen plays an important role in various plant functions, including metabolism, resource allocation, growth, and development (Crawford, N. M., “Nitrate: Nutrient and Signal for Plant Growth,”Plant Cell7:859-868 (1995); Marschner, M.,Mineral Nutrition of Higher Plants,2d ed., Academic Press Ltd.: London (1995); and Stiit et al., “The Molecular Physiological Basis for the Interaction Between Elevated Carbon Dioxide and Nutrients,”Plant Cell Environ.22:583-622 (1999)). Further, nitrogen is a major component of proteins and nucleic acids, as well as various secondary metabolites found in plants (Marschner, M.,Mineral Nutrition of Higher Plants,2d ed., Academic Press Ltd.: London (1995)). Therefore, nitrogen is one of the most important inorganic nutrients of plants. Inorganic nitrogen is added to many crop plants in the form of nitrogenous fertilizers (see Frink et al., “Nitrogen Fertilizer: Retrospect and Prospect,”Proc. Natl. Acad. Sci. USA96:1175-1180 (1999)). Nitrogen is principally added to the soil in the form of ammonia (NH4+) and nitrate (NO3−). However, estimates of nitrogen uptake efficency have shown that between 50 and 70 percent of the applied nitrogen is lost from the plant-soil system (Peoples et al., “Minimizing Gaseous Losses of Nitrogen,” InNitrogen Fertilizer in the Environment,Bacon, P. E., ed., Marcel Dekker, pp. 565-606 (1995)).
The application of inorganic nutrient fertilizers is one of the major expenses incurred by producers of high-yielding crop plants (see Good et al., “Can Less Yield More? Is Reducing Nutrient Input Into the Environment Compatible with Maintaining Crop Production?”Trends in Plant Science9(12):597-605 (2004)). Further, reports have indicated that nitrogen-based fertilizers may be associated with environmental damage (see Vitousek et al., “Human Alternation of the Global Nitrogen Cycle: Causes and Consequences,”Ecol. Appl.7:737-750 (1997)). Therefore, one important way of decreasing the amount of inorganic nitrogen that is applied to plant crops is to develop ways to improve nitrate use efficiency (“NUE”) in plants.
Traditional plant breeding and marker-assisted selection are techniques that have been investigated for developing and identifying plants with increased NUE (see Good et al., “Can Less Yield More? Is Reducing Nutrient Input Into the Environment Compatible with Maintaining Crop Production?”Trends in Plant Science9(12):597-605 (2004)). However, these approaches are often time-consuming and labor-intensive. An alternative approach is to use genetic engineering techniques to develop transgenic crop plants that have enhanced NUE. This approach requires the identification of genes that enhance NUE. Efforts have been reported regarding identifying genes that are regulated by nitrogen levels inArabidopsis(Scheible et al., “Genome-Wide Reprogramming of Primary and Secondary Metabolism, Protein Synthesis, Cellular Growth Processes, and the Regulatory Infrastructure ofArabidopsisin Response to Nitrogen,”Plant Physiol.136:2483-2499 (2004)). However, there is a need to identify genes that are involved in nitrate uptake and metabolism in economically important crop plants such as corn.
The present invention is directed to overcoming these and other deficiencies in the art.
The present invention relates to nucleic acid molecules from corn (maize) that are modulated by nitrogen (e.g., that up-regulated by nitrogen). The present invention also relates to isolated proteins or polypeptides encoded by the nucleic acid molecues. The present invention further relates to promoters of the nucleic acid molecules of the present invention.
The present invention further relates to a nucleic acid construct having a nucleic acid molecule of the present invention (i.e., a nucleic acid molecule that is modulated, e.g., up-regulated, by nitrogen in corn). The construct also includes a 5′ DNA promoter sequence and a 3′ terminator sequence. The nucleic acid molecule, the DNA promoter sequence, and the terminator sequence are operatively coupled to permit transcription of the nucleic acid molecule.
The present invention also relates to an expression system, host cells, plant cells, plants, and plant seeds having a nucleic acid construct that includes a nucleic acid molecule that is modulated by nitrogen in corn.
Another aspect of the present invention is a method of expressing a nucleic acid molecule that is modulated by nitrogen in a plant. This method involves providing a transgenic plant or plant seed transformed with a nucleic acid construct having a nucleic acid molecule that is modulated by nitrogen in corn, a 5′ DNA promoter sequence, and a 3′ terminator sequence. The method involves growing the transgenic plant or a transgenic plant grown from the transgenic plant seed under conditions effective to express the nucleic acid molecule in the transgenic plant or the plant grown from the transgenic plant seed.
Another aspect of the present invention relates to an isolated DNA promoter from corn suitable for inducing nitrogen-regulated expression of a protein encoded by an isolated DNA molecule operably associated with the DNA promoter. The present invention further relates to a nucleic acid construct including the isolated DNA promoter, as well as expression vectors, host cells, plants, and plant seeds containing the nucleic acid construct. The present invention also relates to a method of directing nitrogen-regulated expression of an isolated nucleic acid in plants. This method involves transforming a plant cell with the nucleic acid construct described in this paragraph and regenerating a plant from the transformed plant cell. By this method, expression of the nucleic acid molecule, under control of the DNA promoter, occurs in the plant and is upregulated by nitrogen.
Nitrate use efficiency affects both grower profitability and the ecological sustainability of intensive corn production. The present invention is effective in providing a means to improve the NUE by enhancing the nitrogen uptake of crop plants such as corn. In particular, the nucleic acid constructs of the present invention can be used to develop corn germplasm using marker-assisted selection and/or transgenic approaches. Thus, the present invention is useful in increasing the nitrate absorption and usage efficiency by crop plants and thus reduce the use of nitrate supplements. The nucleic acid constructs of the present invention include nucleic acid molecules corresponding to genes of corn plants and, hence, have the most direct bearing on nitrate metabolism in corn. Therefore, such genes may be more directly relevant to corn improvement than genes from non-crop plants such asArabidopsis.
The present invention relates to nucleic acid molecules (e.g., genes) from corn (maize) (e.g., from B73 seedlings) that are modulated (e.g., up-regulated) by nitrogen (e.g., in the form of nitrate, calcium nitrate, etc.). These genes and their promoters are natural targets for use in corn improvement. These genes can be used to improve corn germplasm with the use of marker-assisted selection and/or transgenic approaches. The present invention provides nucleotide sequences of the full-length cDNA clones of such genes. The present invention also provides the amino acid sequences of the isolated proteins or polypeptides encoded by these genes, as well as their putative promoters (upstream of transcription start site of the genes).
A suitable nucleic acid molecule of the present invention is a gene that is up-regulated by nitrogen and contained in a full-length cDNA clone having the nucleotide sequence of SEQ ID NO:1, as follows:

The present invention relates to a nucleic acid construct having a nucleic acid molecule that is modulated by nitrogen in corn. The construct also includes a 5′ DNA promoter sequence and a 3′ terminator sequence. The nucleic acid molecule, the DNA promoter sequence, and the terminator sequence are operatively coupled to permit transcription of the nucleic acid molecule.
The nucleic acid molecules of the present invention may be inserted into any of the many available expression vectors and cell systems using reagents that are well known in the art. Suitable vectors include, but are not limited to, the following viral vectors such as lambda vector system gt11, gt WES.tB, Charon 4, and plasmid vectors such as pG-Cha, p35S-Cha, pBR322, pBR325, pACYC177, pACYC1084, pUC8, pUC9, pUC18, pUC19, pLG339, pR290, pKC37, pKC101, SV40, pBluescript II SK± or KS± (see “Stratagene Cloning Systems” Catalog (1993) from Stratagene, La Jolla, Calif., which is hereby incorporated by reference in its entirety), pQE, pIH821, pGEX, pET series (see Studier et. al., “Use of T7 RNA Polymerase to Direct Expression of Cloned Genes,”Gene Expression Technologyvol. 185 (1990), which is hereby incorporated by reference in its entirety), and any derivatives thereof. Recombinant molecules can be introduced into cells via transformation, particularly transduction, conjugation, mobilization, or electroporation. The DNA sequences are cloned into the vector using standard cloning procedures in the art, as described by Sambrook et al.,Molecular Cloning: A Laboratory Manual,Second Edition, Cold Spring Harbor, N.Y.: Cold Spring Harbor Press (1989), and Ausubel et al.,Current Protocols in Molecular Biology,New York, N.Y.; John Wiley & Sons (1989), which are hereby incorporated by reference in their entirety.
In preparing a nucleic acid vector for expression, the various nucleic acid molecule sequences may normally be inserted or substituted into a bacterial plasmid. Any convenient plasmid may be employed, which will be characterized by having a bacterial replication system, a marker which allows for selection in a bacterium, and generally one or more unique, conveniently located restriction sites. Numerous plasmids, referred to as transformation vectors, are available for plant transformation. The selection of a vector will depend on the preferred transformation technique and target species for transformation. A variety of vectors are available for stable transformation usingAgrobacterium tumefaciens,a soilborne bacterium that causes crown gall. Crown gall are characterized by tumors or galls that develop on the lower stem and main roots of the infected plant. These tumors are due to the transfer and incorporation of part of the bacterium plasmid DNA into the plant chromosomal DNA. This transfer DNA (T-DNA) is expressed along with the normal genes of the plant cell. The plasmid DNA, pTi, or Ti-DNA, for “tumor inducing plasmid,” contains the vir genes necessary for movement of the T-DNA into the plant. The T-DNA carries genes that encode proteins involved in the biosynthesis of plant regulatory factors, and bacterial nutrients (opines). The T-DNA is delimited by two 25 bp imperfect direct repeat sequences called the “border sequences.” By removing the oncogene and opine genes, and replacing them with a gene of interest, it is possible to transfer foreign DNA into the plant without the formation of tumors or the multiplication ofAgrobacterium tumefaciens(Fraley et al., “Expression of Bacterial Genes in Plant Cells,”Proc. Nat'l Acad. Sci.80:4803-4807 (1983), which is hereby incorporated by reference in its entirety).
Further improvement of this technique led to the development of the binary vector system (Bevan, “BinaryAgrobacteriumVectors for Plant Transformation,”Nucleic Acids Res.12:8711-8721 (1984), which is hereby incorporated by reference in its entirety). In this system, all the T-DNA sequences (including the borders) are removed from the pTi, and a second vector containing T-DNA is introduced intoAgrobacterium tumefaciens.This second vector has the advantage of being replicable inE. colias well asA. tumefaciens,and contains a multiclonal site that facilitates the cloning of a transgene. An example of a commonly-used vector is pBin19 (Frisch et al., “Complete Sequence of the Binary Vector Bin 19,” Plant Molec. Biol27:405-409 (1995), which is hereby incorporated by reference in its entirety). Any appropriate vectors now known or later described for genetic transformation are suitable for use with the present invention.
U.S. Pat. No. 4,237,224 to Cohen and Boyer, which is hereby incorporated by reference in its entirety, describes the production of expression systems in the form of recombinant plasmids using restriction enzyme cleavage and ligation with DNA ligase. These recombinant plasmids are then introduced by means of transformation and replicated in unicellular cultures including prokaryotic organisms and eukaryotic cells grown in tissue culture.
Certain “control elements” or “regulatory sequences” are also incorporated into the vector-construct. These include non-translated regions of the vector, promoters, and 5′ and 3′ untranslated regions which interact with host cellular proteins to carry out transcription and translation. Such elements may vary in their strength and specificity. Depending on the vector system and host utilized, any number of suitable transcription and translation elements, including constitutive and inducible promoters, may be used. Tissue-specific and organ-specific promoters can also be used.
A constitutive promoter is a promoter that directs expression of a gene throughout the development and life of an organism. Examples of some constitutive promoters that are widely used for inducing expression of transgenes include the nopaline synthase (“NOS”) gene promoter fromAgrobacterium tumefaciens(U.S. Pat. No. 5,034,322 to Rogers et al., which is hereby incorporated by reference in its entirety), the cauliflower mosaic virus (“CaMY”) 35S and 19S promoters (U.S. Pat. No. 5,352,605 to Fraley et al., which is hereby incorporated by reference in its entirety), those derived from any of the several actin genes, which are known to be expressed in most cells types (U.S. Pat. No. 6,002,068 to Privalle et al., which is hereby incorporated by reference in its entirety), and the ubiquitin promoter, which is a gene product known to accumulate in many cell types.
An inducible promoter is a promoter that is capable of directly or indirectly activating transcription of one or more DNA sequences or genes in response to an inducer. In the absence of an inducer, the DNA sequences or genes will not be transcribed. The inducer can be a nutrient (e.g., nitrogen, including nitrogen in the form of nitrate), a chemical agent, such as a metabolite, growth regulator, herbicide, or phenolic compound, or a physiological stress directly imposed upon the plant such as cold, heat, salt, toxins, or through the action of a pathogen or disease agent such as a virus or fungus. A plant cell containing an inducible promoter may be exposed to an inducer by externally applying the inducer to the cell or plant such as by spraying, watering, heating, or by exposure to the operative pathogen. An example of an appropriate inducible promoter is a glucocorticoid-inducible promoter (Schena et al., “A Steroid-Inducible Gene Expression System for Plant Cells,”Proc. Natl. Acad. Sci.88:10421-5 (1991), which is hereby incorporated by reference in its entirety). Expression of the transgene-encoded protein is induced in the transformed plants when the transgenic plants are brought into contact with nanomolar concentrations of a glucocorticoid, or by contact with dexamethasone, a glucocorticoid analog (see Schena et al., “A Steroid-Inducible Gene Expression System for Plant Cells,”Proc. Natl. Acad. Sci. USA88:10421-5 (1991); Aoyama et al., “A Glucocorticoid-Mediated Transcriptional Induction System in Transgenic Plants,”Plant J.11:605-612 (1997); and McNellis et al., “Glucocorticoid-Inducible Expression of a Bacterial Avirulence Gene in Transgenic Arabidopsis Induces Hypersensitive Cell Death,Plant J.14(2):247-57 (1998), which are hereby incorporated by reference in their entirety). In addition, inducible promoters include promoters that function in a tissue specific manner to regulate the gene of interest within selected tissues of the plant. Examples of such tissue specific or developmentally regulated promoters include seed, flower, fruit, or root specific promoters as are well known in the field (U.S. Pat. No. 5,750,385 to Shewmaker et al., which is hereby incorporated by reference in its entirety).
A number of tissue- and organ-specific promoters have been developed for use in genetic engineering of plants (Potenza et al., “Targeting Transgene Expression in Research, Agricultural, and Environmental Applications: Promoters used in Plant Transformation,”In Vitro Cell. Dev. Biol. Plant40:1-22 (2004), which is hereby incorporated by reference in its entirety). Examples of such promoters include those that are floral-specific (Annadana et al., “Cloning of the Chrysanthemum UEP1 Promoter and Comparative Expression in Florets and Leaves ofDendranthema grandiflora,” Transgenic Res.11:437-445(2002), which is hereby incorporated by reference in its entirety), seed-specific (Kluth et al., “5′ Deletion of a gbss1 Promoter Region Leads to Changes in Tissue and Developmental Specificities,”Plant Mol. Biol.49:669-682 (2002), which is hereby incorporated by reference in its entirety), root-specific (Yamamoto et al., “Characterization of cis-acting Sequences Regulating Root-Specific Gene Expression in Tobacco,”Plant Cell3:371-382 (1991), which is hereby incorporated by reference in its entirety), fruit-specific (Fraser et al., “Evaluation of Transgenic Tomato Plants Expressing an Additional Phytoene Synthase in a Fruit-Specific Manner,”Proc. Natl Acad. Sci. USA99:1092-1097 (2002), which is hereby incorporated by reference in its entirety), and tuber/storage organ-specific (Visser et al., “Expression of a Chimaeric Granule-Bound Starch Synthase-GUS gene in transgenic Potato Plants,”Plant Mol Biol.17:691-699 (1991), which is hereby incorporated by reference in its entirety). Targeted expression of an introduced gene (transgene) is necessary when expression of the transgene could have detrimental effects if expressed throughout the plant. On the other hand, silencing a gene throughout a plant could also have negative effects. However, this problem could be avoided by localizing the silencing to a region by a tissue-specific promoter.
A suitable promoter can also be one that is gene-specific, in that it regulates transcription of a nucleic acid molecule of the present invention. A suitable gene-specific promoter gene-specific promoter (derived from MAGI93503) has a nucleotide sequence of SEQ ID NO:41 as follows:

This gene-specific promoter is a fragment of genomic DNA of maize that is likely to include promoter elements that allow the gene of SEQ ID NO:39 to exhibit nitrogen-regulated expression. Other suitable promoters include those having a nucleotide sequence of SEQ ID NO:3, SEQ ID NO:6, SEQ ID NO:9, SEQ ID NO:12, SEQ ID NO:15, SEQ ID NO:18, SEQ ID NO:21, SEQ ID NO:26, SEQ ID NO:29, SEQ ID NO:33, SEQ ID NO:38, SEQ ID NO:41, and/or SEQ ID NO:46.
The nucleic acid construct of the present invention also includes an operable 3′ regulatory region, selected from among those which are capable of providing correct transcription termination and polyadenylation of mRNA for expression in the host cell of choice, operably linked to a modified trait nucleic acid molecule of the present invention. A number of 3′ regulatory regions are known to be operable in plants. Exemplary 3′ regulatory regions include, without limitation, the nopaline synthase (NOS) 3′ regulatory region (Fraley et al., “Expression of Bacterial Genes in Plant Cells,”Proc. Nat'l Acad. Sci. USA80:4803-4807 (1983), which is hereby incorporated by reference in its entirety) and the cauliflower mosaic virus (CaMV) 3′ regulatory region (Odell et al., “Identification of DNA Sequences Required for Activity of the Cauliflower Mosaic Virus35S Promoter,”Nature313(6005):810-812 (1985), which is hereby incorporated by reference in its entirety). Virtually any 3′ regulatory region known to be operable in plants would be suitable for use in conjunction with the present invention.
The different components described above can be ligated together to produce expression systems which contain the nucleic acid constructs of the present invention, using well known molecular cloning techniques as described in Sambrook et al.,Molecular Cloning: A Laboratory Manual,Second Edition Cold Spring Harbor, N.Y.: Cold Spring Harbor Press (1989), and Ausubel et al.Current Protocols in Molecular Biology,New York, N.Y.: John Wiley & Sons (1989), which are hereby incorporated by reference in their entirety.
Once the nucleic acid construct of the present invention has been prepared, it is ready to be incorporated into a host cell. Accordingly, another aspect of the present invention relates to a recombinant host cell containing one or more of the nucleic acid constructs of the present invention. Basically, this method is carried out by transforming a host cell with a nucleic acid construct of the present invention under conditions effective to achieve transcription of the nucleic acid molecule in the host cell. This is achieved with standard cloning procedures known in the art, such as described by Sambrook et al.,Molecular Cloning: A Laboratory Manual,Second Edition, Cold Springs Laboratory, Cold Springs Harbor, N.Y. (1989), which is hereby incorporated by reference in its entirety. Suitable hosts include, but are not limited to, bacterial cells, viruses, yeast cells, mammalian cells, insect cells, plant cells, and the like. Preferably the host is either a bacterial cell or a plant cell. Methods of transformation may result in transient or stable expression of the nucleic acid under control of the promoter. Preferably, a nucleic acid construct of the present invention is stably inserted into the genome of the recombinant plant cell as a result of the transformation, although transient expression can serve an important purpose, particularly when the plant under investigation is slow-growing.
Plant tissue suitable for transformation includes leaf tissue, root tissue, meristems, zygotic and somatic embryos, callus, protoplasts, tassels, pollen, embryos, anthers, and the like. The means of transformation chosen is that most suited to the tissue to be transformed.
Transient expression in plant tissue can be achieved by particle bombardment (Klein et al., “High-Velocity Microprojectiles for Delivering Nucleic Acids Into Living Cells,”Nature327:70-73 (1987), which is hereby incorporated by reference in its entirety), also known as biolistic transformation of the host cell, as disclosed in U.S. Pat. Nos. 4,945,050, 5,036,006, and 5,100,792, all to Sanford et al., and in Emerschad et al., “Somatic Embryogenesis and Plant Development from Immature Zygotic Embryos of Seedless Grapes (Vitis vinifera),”Plant Cell Reports14:6-12 (1995), which are hereby incorporated by reference in their entirety.
In particle bombardment, tungsten or gold microparticles (1 to 2 μm in diameter) are coated with the DNA of interest and then bombarded at the tissue using high pressure gas. In this way, it is possible to deliver foreign DNA into the nucleus and obtain a temporal expression of the gene under the current conditions of the tissue. Biologically active particles (e.g., dried bacterial cells containing the vector and heterologous DNA) can also be propelled into plant cells. Other variations of particle bombardment, now known or hereafter developed, can also be used. Further, particle bombardment transformation can be used to stably introduce the nucleic acid construct into plant cells.
Another appropriate method of stably introducing the nucleic acid construct into plant cells is to infect a plant cell withAgrobacterium tumefaciensorAgrobacterium rhizogenespreviously transformed with the nucleic acid construct. As described above, the Ti (or RI) plasmid of Agrobacterium enables the highly successful transfer of a foreign nucleic acid molecule into plant cells. A variation ofAgrobacterium transformationuses vacuum infiltration in which whole plants are used (Senior, “Uses of Plant Gene Silencing,”Biotechnology and Genetic Engineering Reviews15:79-119 (1998), which is hereby incorporated by reference in its entirety).
Yet another method of introduction is fusion of protoplasts with other entities, either minicells, cells, lysosomes, or other fusible lipid-surfaced bodies (Fraley et al.,Proc. Natl. Acad. Sci. USA79:1859-63 (1982), which is hereby incorporated by reference in its entirety). The nucleic acid molecule may also be introduced into the plant cells by electroporation (Fromm et al.,Proc. Natl Acad. Sci. USA82:5824 (1985), which is hereby incorporated by reference in its entirety). 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. Other methods of transformation include polyethylene-mediated plant transformation, micro-injection, physical abrasives, and laser beams (Senior, “Uses of Plant Gene Silencing,”Biotechnology and Genetic Engineering Reviews15:79-119 (1998), which is hereby incorporated by reference in its entirety). The precise method of transformation is not critical to the practice of the present invention. Any method that results in efficient transformation of the host cell of choice is appropriate for practicing the present invention. Transfromation can also be achieved using the “whisker” method, as is well known in the art.
After transformation, the transformed plant cells must be regenerated. Plant regeneration from cultured protoplasts is described in Evans et al.,Handbook of Plant Cell Cultures,Vol 1, New York, N.Y.: MacMillan Publishing Co. (1983); Vasil, ed.,Cell Culture and Somatic Cell Genetics of Plants,Vol. I (1984) and Vol. III (1986), Orlando: Acad. Press, which are hereby incorporated by reference in their entirety.
Means for regeneration vary from species to species of plants, but generally a suspension of transformed protoplasts or a petri plate containing explants is first provided. Callus tissue is formed and shoots may be induced from callus and subsequently rooted. Alternatively, embryo formation can be induced in the callus tissue. These embryos germinate as natural embryos to form plants. The culture media will generally contain various amino acids and hormones, such as auxin and cytokinins. 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.
Preferably, transformed cells are first identified using a selection marker simultaneously introduced into the host cells along with the nucleic acid construct of the present invention. Suitable selection markers include, without limitation, markers encoding for antibiotic resistance, such as the neomycin phosphotransferae II (“nptII”) gene which confers kanamycin resistance (Fraley et al.,Proc. Natl. Acad. Sci. USA80:4803-4807 (1983), which is hereby incorporated by reference in its entirety), and the genes which confer resistance to gentamycin, G418, hygromycin, streptomycin, spectinomycin, tetracycline, chloramphenicol, and the like. Cells or tissues are grown on a selection medium containing the appropriate antibiotic, whereby generally only those transformants expressing the antibiotic resistance marker continue to grow. Other types of markers are also suitable for inclusion in the expression cassette of the present invention. For example, a gene encoding for herbicide tolerance, such as tolerance to sulfonylurea is useful, or the dhfr gene, which confers resistance to methotrexate (Bourouis et al.,EMBO J.2:1099-1104 (1983), which is hereby incorporated by reference in its entirety). Similarly, “reporter genes,” which encode for enzymes providing for production of an identifiable compound are suitable. The most widely used reporter gene for gene fusion experiments has been uidA, a gene fromEscherichia colithat encodes the β-glucuronidase protein, also known as GUS (Jefferson et al., “GUS Fusions: β Glucuronidase as a Sensitive and Versatile Gene Fusion Marker in Higher Plants,”EMBO J6:3901-3907 (1987), which is hereby incorporated by reference in its entirety). Similarly, enzymes providing for production of a compound identifiable by luminescence, such as luciferase, are useful. The selection marker employed will depend on the target species; for certain target species, different antibiotics, herbicide, or biosynthesis selection markers are preferred.
Plant cells and tissues selected by means of an inhibitory agent or other selection marker are then tested for the acquisition of the transgene (Sambrook et al.,Molecular Cloning: A Laboratory Manual,Cold Spring Harbor, N.Y.: Cold Spring Harbor Press (1989), which is hereby incorporated by reference in its entirety).
After the fusion gene containing a nucleic acid construct of the present invention is stably incorporated in transgenic plants, the transgene can be transferred to other plants by sexual crossing. Any of a number of standard breeding techniques10 can be used, depending upon the species to be crossed. Once transgenic plants of this type are produced, the plants themselves can be cultivated in accordance with conventional procedure so that the nucleic acid construct is present in the resulting plants. Alternatively, transgenic seeds are recovered from the transgenic plants. These seeds can then be planted in the soil and cultivated using conventional procedures to produce transgenic plants. The component parts and fruit of such plants are encompassed by the present invention.
The present invention can be utilized in conjunction with a wide variety of plants or their seeds. Suitable plants can include dicots and monocots. More particular, suitable plants can include the following: rice, corn, soybean, canola, potato, wheat, mung bean, alfalfa, barley, rye, cotton, sunflower, peanut, sweet potato, bean, pea, chicory, lettuce, endive, cabbage, brussel sprout, beet, parsnip, turnip, cauliflower, broccoli, radish, spinach, onion, garlic, eggplant, pepper, celery, carrot, squash, pumpkin, zucchini, cucumber, apple, pear, melon, citrus, strawberry, grape, raspberry, pineapple, tobacco, tomato, sorghum, sugarcane, banana,Arabidopsis thaliana, Saintpaulia,petunia, pelargonium, poinsettia, chrysanthemum, carnation, crocus, marigold, daffodil, pine,Medicago truncatula, Sandersonlia aurantiaca,and zinnia.
Another aspect of the present invention is a method of expressing a nucleic acid molecule that is modulated by nitrogen in a plant. This method involves providing a transgenic plant or plant seed transformed with a nucleic acid construct having a nucleic acid molecule that is modulated by nitrogen in corn, a 5′ DNA promoter sequence, and a 3′ terminator sequence. The nucleic acid molecule, the DNA promoter sequence, and the terminator sequence are operatively coupled to permit transcription of the nucleic acid molecule. The method also involves growing the transgenic plant or a transgenic plant grown from the transgenic plant seed under conditions effective to express the nucleic acid molecule in the transgenic plant or the plant grown from the transgenic plant seed. In one embodiment, the transgenic plant or plant seed is provided by transforming a non-transgenic plant or a non-transgenic plant seed with the nucleic acid construct of the present invention to yield said transgenic plant or plant seed. In one aspect, the growing step is effective in reducing nitrogen uptake of the transgenic plant or the plant grown from the transgenic plant seed. In another aspect, the growing step is effective in increasing nitrogen uptake of the transgenic plant or the plant grown from the transgenic plant seed. In yet another aspect, the growing step is effective in increasing efficiency of nitrogen utilization of the transgenic plant or the plant grown from the transgenic plant seed. Transformation of the transgenic plant or plant seed can be achieved usingAgrobacterium-mediated transformation, the whisker method, vacuum infiltration, biolistic transformation, electroporation, micro-injection, polyethylene-mediated transformation, or laser-beam transformation.
The present invention also relates to an isolated DNA promoter from corn suitable for inducing nitrogen-regulated expression of a protein encoded by an isolated DNA molecule operably associated with the DNA promoter. A suitable DNA promoter for use in this method can be any one of the promoters described herein, including, for example, the promoters having a nucleotide sequence of SEQ ID NO:3, SEQ ID NO:6, SEQ ID NO:9, SEQ ID NO:12, SEQ ID NO:15, SEQ ID NO:18, SEQ ID NO:21, SEQ ID NO:26, SEQ ID NO:29, SEQ ID NO:33, SEQ ID NO:38, SEQ ID NO:41, and/or SEQ ID NO:46. The isolated DNA promoter can be used to prepare nucleic acid constructs as previously described. In a particular nucleic acid construct, the isolated DNA promoter can be operably linked to an isolated nucleic acid that either has a nucleotide sequence (or encoding portion thereof) of SEQ ID NO:1, SEQ ID NO:4, SEQ ID NO:7, SEQ ID NO:10, SEQ ID NO:13, SEQ ID NO:16, SEQ ID NO:19, SEQ ID NO:22, SEQ ID NO:24, SEQ ID NO:27, SEQ ID NO:30, SEQ ID NO:34, SEQ ID NO:36, SEQ ID NO:39, SEQ ID NO:42, and/or SEQ ID NO:44, or encodes a polypeptide having an amino acid sequence of SEQ ID NO:2, SEQ ID NO:5, SEQ ID NO:8, SEQ ID NO:11, SEQ ID NO:14, SEQ ID NO:17, SEQ ID NO:20, SEQ ID NO:23, SEQ ID NO:25, SEQ ID NO:28, SEQ ID NO:31, SEQ ID NO:32, SEQ ID NO:35, SEQ ID NO:37, SEQ ID NO:40, SEQ ID NO:43, and/or SEQ ID NO:45. Other suitable genes from corn that can be regulated by the DNA promoter of the present invention include, for example, nitrate reductase, nitrite reductase, Uroporphyrin-III methyl transferase. Expression vectors can be prepared by inserting the nucleic acid construct in an appropriate vector (as described in more detail supra), and transgenic host cells and plants (including their component parts such as fruits and seeds) can be produced by transforming them with the nucleic acid construct containing the DNA promoter.
The present invention also relates to a method of directing nitrogen-regulated expression of an isolated nucleic acid in plants. This methods involves transforming a plant cell with the nucleic acid construct that includes an isolated DNA promoter suitable for inducing nitrogenregulated expression of a protein encoded by an isolated DNA molecule operably associated with the DNA promoter. This method also involves regenerating a plant from the transformed plant cell. By this method, expression of the nucleic acid molecule, under control of the DNA promoter, occurs in the plant and is upregulated by nitrogen. A suitable DNA promoter for use in this method can be any one of the promoters described herein, including, for example, the promoters having a nucleotide sequence of SEQ ID NO:3, SEQ ID NO:6, SEQ ID NO:9, SEQ ID NO:12, SEQ ID NO:15, SEQ ID NO:18, SEQ ID NO:21, SEQ ID NO:26, SEQ ID NO:29, SEQ ID NO:33, SEQ ID NO:38, SEQ ID NO:41, and/or SEQ ID NO:46.
