Abstract
A transgenic plant transformed by an Ion Transporter Stress-Related Polypeptide (ITSRP) coding nucleic acid, wherein expression of the nucleic acid sequence in the plant results in increased tolerance to 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 ITSRPs, and isolated nucleic acid coding ITSRPs, and vectors and host cells containing the latter.
Claims30
An isolated nucleic acid, wherein the nucleic acid comprises a polynucleotide selected from the group consisting of:
- a) a polynucleotide as defined in SEQ ID NO:
- 5;
- b) a polynucleotide encoding a polypeptide as defined in SEQ ID NO:
- 6;
- c) a polynucleotide having at least 90% sequence identity to SEQ ID NO:
- 5;
- and d) a polynucleotide encoding a polypeptide having at least 95% sequence identity to SEQ ID NO:
- 6;
- wherein a polypeptide encoded by the polynucleotide, of a)–d) when expressed in a plant confers increased tolerance to the plant against high salinity, drought and low temperature.
A method of producing a transgenic plant containing a nucleic acid wherein the plant has an increased tolerance to an environmental stress of high salinity, drought or low temperature as compared to a wild type variety of the plant comprising, transforming a plant cell with an expression vector comprising the nucleic acid and regenerating from the plant cell the transgenic plant, wherein the nucleic acid encodes a polypeptide that functions to increase a plant's stress response, and wherein the nucleic acid is selected from the group consisting of:
- a) a polynucleotide as defined in SEQ ID NO:
- 5;
- b) a polynucleotide encoding a polypeptide as defined in SEQ ID NO:
- 6;
- c) a polynucleotide encoding a polypeptide having at least 95% sequence identity with the polypeptide as defined in SEQ ID NO:
- 6;
- and d) a polynucleotide having at least 90% sequence identity to SEQ ID NO:
- 5;
- wherein a polypeptide encoded by the polynucleotide, of a)–d) when expressed in a plant confers increased tolerance to the plant against high salinity, drought and low temperature.
