Abstract
A transgenic plant transformed with an SLSRP coding nucleic acid, wherein expression of the nucleic acid sequence in the plant results in increased growth under water-limited conditions and/or increased tolerance to an environmental stress as compared to a wild type variety of the plant. Also provided are agricultural products, including seeds, produced by the transgenic plants. Also provided are isolated SLSRPs, and isolated SLSRP coding nucleic acids, and vectors and host cells containing the latter.
Claims18
A transgenic plant transformed with a polynucleotide selected from the group consisting of:
- a) a polynucleotide sequence encoding a polypeptide comprising amino acids 1 to 657 of SEQ ID NO:6;
- b) a polynucleotide sequence comprising nucleotides 1 to 2281 of SEQ ID NO:5;
- and
- c) a polynucleotide sequence comprising nucleotides 218 to 2191 of SEQ ID NO:5;
- wherein expression of the polynucleotide in the plant results in increased tolerance to drought stress, as compared to a wild type variety of the plant.
A transgenic seed which is true breeding for a polynucleotide selected from the group consisting of:
- a) a polynucleotide sequence encoding a polypeptide comprising amino acids 1 to 657 of SEQ ID NO:6;
- b) a polynucleotide sequence comprising nucleotides 1 to 2281 of SEQ ID NO:5;
- and
- c) a polynucleotide sequence comprising nucleotides 218 to 2191 of SEQ ID NO:5;
- wherein a transgenic plant grown from said seed has increased tolerance to drought stress, as compared to a wild type variety of the plant.
An isolated polynucleotide selected from the group consisting of:
- a) a polynucleotide sequence encoding a polypeptide comprising amino acids 1 to 657 of SEQ ID NO:6;
- b) a polynucleotide sequence comprising nucleotides 1 to 2281 of SEQ ID NO:5;
- and
- c) a polynucleotide sequence comprising nucleotides 218 to 2191 of SEQ ID NO:5.
A recombinant expression vector comprising a polynucleotide selected from the group consisting of:
- a) a polynucleotide sequence encoding a polypeptide comprising amino acids 1 to 657 of SEQ ID NO:6;
- b) a polynucleotide sequence comprising nucleotides 1 to 2281 of SEQ ID NO:5;
- and
- c) a polynucleotide sequence comprising nucleotides 218 to 2191 of SEQ ID NO:5.
A method of producing a drought-tolerant transgenic plant comprising the steps of:
- a) transforming a plant cell with an expression vector comprising a polynucleotide selected from the group consisting of:
- i) a polynucleotide sequence encoding a polypeptide comprising amino acids 1 to 657 of SEQ ID NO:6;
- ii) a polynucleotide sequence comprising nucleotides 1 to 2281 of SEQ ID NO:5;
- and
- iii) a polynucleotide sequence comprising nucleotides 218 to 2191 of SEQ ID NO:5;
- and
- b) generating a transgenic plant from the transformed plant cell, wherein the transgenic plant expressing the polynucleotide is drought tolerant.
