Abstract
Water deficit-inducible promoter sequences were identified that may be used to produce transgenic plants that are more tolerant to water deficit and related hyperosmotic stresses than control plants, and yet are wild-type or nearly wild type in appearance. Any of these water deficit-inducible promoters may be incorporated into an expression vector that comprises a polynucleotide regulated by one such promoter and which encodes a polypeptide that, when ectopically expressed, improves water deficit tolerance in plants that are similar to control plants in their morphology and development.
Claims19
A plant cell comprising a recombinant polynucleotide comprising a nucleotide sequence and a promoter that has water deficit-inducible promoter activity, wherein the promoter is operably linked to the nucleotide sequence to which it is not operably linked in nature, wherein said promoter has at least 98% identity to the polynucleotide sequence of SEQ ID NO:
- 6.
A transgenic plant comprising a recombinant polynucleotide comprising a nucleotide sequence and a promoter that has a water deficit-inducible promoter activity, wherein the promoter is operably linked to the nucleotide sequence to which it is not operably linked in nature,
- wherein said promoter has at least 98% identity to the sequence of SEQ ID NO:
- 6.
A transgenic plant comprising a recombinant polynucleotide comprising a nucleotide sequence and a promoter that has a water deficit-inducible promoter activity, wherein the promoter is operably linked to the nucleotide sequence to which it is not operably linked in nature, wherein said promoter has at least 98% identity to the polynucleotide sequence of SEQ ID NO:
- 6.
A transgenic plant comprising SEQ ID NO:
- 15.
