Abstract
Compositions and methods and for enhancing the resistance of plants to a plant disease caused by a Phytophthora species are provided. The compositions comprise nucleic acid molecules encoding resistance (R) gene products and variants thereof and plants, seeds, and plant cells comprising such nucleic acid molecules. The methods for enhancing the resistance of a plant to a plant disease caused by a Phytophthora species comprise introducing a nucleic acid molecule encoding an R gene product into a plant cell. Additionally provided are methods for using the plants in agriculture to limit plant disease.
Claims10
A transgenic solanaceous plant or plant cell comprising stably incorporated in its genome a heterologous polynucleotide comprising a nucleotide sequence selected from the group consisting of:
- (a) the nucleotide sequence set forth in SEQ ID NO:
- 1;
- (b) a nucleotide sequence encoding the amino acid sequence set forth in SEQ ID NO:
- 2;
- and
- (c) the nucleotide sequence set forth in SEQ ID NO:
- 3.
A method for making a transgenic solanaceous plant or plant cell comprising enhanced resistance to a plant disease caused by Phytophthora infestans, the method comprising introducing a heterologous polynucleotide into at least one solanaceous plant cell, the heterologous polynucleotide comprising a nucleotide sequence selected from the group consisting of:
- (a) the nucleotide sequence set forth in SEQ ID NO:
- 1;
- (b) a nucleotide sequence encoding the amino acid sequence set forth in SEQ ID NO:
- 2;
- and
- (c) the nucleotide sequence set forth in SEQ ID NO:
- 3.
A method of limiting a plant disease caused by at least one race of at least one Phytophthora sp. in agricultural crop production, the method comprising planting a solanaceous seedling, tuber, or seed and growing the solanaceous seedling, tuber, or seed under conditions favorable for the growth and development of a solanaceous plant resulting therefrom, wherein the solanaceous seedling, tuber, or seed comprising stably incorporated in its genome a heterologous polynucleotide comprising a nucleotide sequence selected from the group consisting of:
- (a) the nucleotide sequence set forth in SEQ ID NO:
- 1;
- (b) a nucleotide sequence encoding the amino acid sequence set forth in SEQ ID NO:
- 2;
- and
- (c) the nucleotide sequence set forth in SEQ ID NO:
- 3.
