Abstract
A transgenic plant engineered to have increased desiccation tolerance, increased drought tolerance or increased water use efficiency, the plant transformed with an artificial DNA construct comprising a transcribable nucleic acid molecule encoding a polypeptide requiring both ABA and ABI3 to influence desiccation tolerance. Also provided are DNA constructs and methods of producing a transgenic plant engineered to have increased desiccation tolerance, increased drought tolerance or increased water use efficiency.
Claims16
A transgenic plant engineered to have increased desiccation tolerance, increased drought tolerance or increased water use efficiency, the plant transformed with an artificial DNA construct comprising, as operably associated components in the 5′ to 3′ direction of transcription:
- a promoter that functions in a plant;
- a polynucleotide selected from the group consisting of SEQ ID NO:
- 1, SEQ ID NO:
- 2, SEQ ID NO:
- 3, SEQ ID NO:
- 4, SEQ ID NO:
- 5, SEQ ID NO:
- 6, SEQ ID NO:
- 7, or SEQ ID NO:
- 8, or a sequence at least 95% identical thereto;
- and
- a transcriptional termination sequence;
- wherein the transgenic plant has an increased desiccation tolerance, increased drought tolerance or increased water use efficiency compared to a plant without the DNA construct.

A method of increasing desiccation tolerance, drought tolerance, or water use efficiency of a plant comprising:
- transforming a plant with an artificial DNA construct comprising, as operably associated components in the 5′ to 3′ direction of transcription:
- a promoter that functions in a plant;
- a polynucleotide selected from the group consisting of SEQ ID NO:
- 1, SEQ ID NO:

- 3, SEQ ID NO:
- 4, SEQ ID NO:
- 5, SEQ ID NO:
- 6, SEQ ID NO:
- 7, or SEQ ID NO:
- 8, or a sequence at least 95% identical thereto;
- and
- a transcriptional termination sequence;
- wherein the transgenic plant has an increased desiccation tolerance, increased drought tolerance, or increased water use efficiency compared to a plant without the DNA construct.
