Stress-inducible plant promoters
The present invention discloses and claims stress-inducible plant promoters, DNA constructs with such promoters, transgenic plants containing such promoters and DNA constructs, isolated DNAs encoding such promoters, and methods of making and using such promoters, DNA constructs, transgenic plants, and isolated DNAs.
1. A transgenic plant having in its genome an exogenous DNA construct comprising a promoter operably linked to a heterologous DNA, wherein said promoter comprises SEQ ID NO:5.
2. The transgenic plant according to claim 1 , wherein said promoter is operably linked to a heterologous DNA which encodes a molecule imparting at least one characteristic selected from the group consisting of insect resistance or tolerance; viral, bacterial, fungal, or nematode disease resistance or tolerance; herbicide resistance or tolerance; enhanced grain composition or quality; enhanced nutrient transporter functions; enhanced nutrient utilization; enhanced environmental stress tolerance or resistance; reduced mycotoxin contamination; male sterility; female sterility; a selectable marker phenotype; a screenable marker phenotype; a negative selectable marker phenotype; a stress-responsive transcription factor; altered plant agronomic characteristics; enhanced kernel development; enhanced embryo development; enhanced general production or protection of next-generation tissues; enhanced grain agronomic characteristics; enhanced grain processing characteristics; and a combination thereof.
3. The transgenic plant according to claim 1 , wherein said heterologous DNA transcribes to RNA imparting gene suppression of at least one gene in said transgenic plant.
4. The transgenic plant according to claim 3 , wherein said heterologous DNA transcribes to double-stranded RNA for suppressing at least one gene in said transgenic plant during stress conditions.
5. The transgenic plant according to claim 1 , selected from the group consisting of crop plants, wood- or pulp-producing trees, vegetable plants, fruit plants, and ornamental plants.
6. The transgenic plant according to claim 1 , selected from the group consisting of wheat, oat, barley, maize, rye, triticale, rice, ornamental and forage grasses, sorghum, millet, sugarcane, coconut, oil palm, date palm, olive, tree nuts, canola, cotton, safflower, soybean, sugarbeet, buckwheat, sunflower, tea, and coffee; wood- or pulp-producing trees; legumes, lettuce, asparagus, artichoke, celery, carrot, radish, amaranth, the brassicas, edible curcubits, edible alliums, edible members of the Solanaceae, and edible members of the Chenopodiaceae; apple, pear, citrus fruit, apricot, peach, plum, nectarine, banana, pineapple, grape, kiwifruit, papaya, avocado, and berries; and ornamental plants.
7. Seed from a transgenic plant of claim 1 , wherein said seed contains said exogenous DNA construct.
8. A DNA construct comprising a promoter operably linked to a heterologous DNA wherein said promoter comprises SEQ ID NO:5.
9. The DNA construct according to claim 8 , wherein said promoter is operably linked to a heterologous DNA which encodes a molecule imparting at least one characteristic selected from the group consisting of insect resistance or tolerance; viral, bacterial, fungal, or nematode disease resistance or tolerance; herbicide resistance or tolerance; enhanced grain composition or quality; enhanced nutrient transporter functions; enhanced nutrient utilization; enhanced environmental stress tolerance or resistance; reduced mycotoxin contamination; male sterility; female sterility; a selectable marker phenotype; a screenable marker phenotype; a negative selectable marker phenotype; a stress-responsive transcription factor; altered plant agronomic characteristics; enhanced kernel development; enhanced embryo development; enhanced general production or protection of next-generation tissues; enhanced grain agronomic characteristics; enhanced grain processing characteristics; and a combination thereof.
10. An isolated DNA comprising the nucleotide sequence of SEQ ID NO:5.
