Abstract
A plant peptide transport gene and its nucleotide sequence are disclosed. The gene may be used to confer herbicide resistance to plants, and to render plants resistant to insect pests. The invention also relates to plants that possess non-naturally occurring alleles of peptide transport gene.
Claims24
A substantially purified polynucleotide which encodes a plant peptide transport protein, has a length greater than 10 nucleotide residues, and hybridizes under low stringency conditions to a nucleotide of SEQ ID NO:1 or SEQ ID NO:3.
A transformed plant cell which contains a substantially purified polynucleotide which encodes a plant peptide transport protein, which polynucleotide has a length greater than 10 nucleotide residues, and hybridizes under low stringency conditions to a nucleotide of SEQ ID NO:1 or SEQ ID NO:3.
A method for increasing the resistance of a plant to an herbicidal peptide which comprises providing a polynucleotide to cells of said plant, said polynucleotide hybridizing under low stringency conditions to a nucleotide of SEQ ID NO:
- 1 or SEQ ID NO:
- 3 and encoding a mutated plant peptide transport protein or a fragment of a plant peptide transport protein, wherein the presence of said polynucleotide and its recombination with the cells' endogenous peptide transport gene impairs the capacity of said cells to transport a plant herbicidal peptide, and thereby increases the resistance of said plant to said herbicidal peptide.
