Abstract
Provided herein is a non-Nicotiana transgenic plant comprising an exogenous polynucleotide encoding Nicotiana benthamiana Roq1 or a variant thereof. These plants have enhanced resistance to at least one species of Xanthomonas, Pseudomonas, Ralstonia, and/or another pathogen containing a homolog of XopQ whose recognition is mediated by Roq1.
Claims9
A transgenic plant comprising an exogenous polynucleotide encoding a polypeptide that is identical to SEQ ID NO:
- 1, wherein the plant is not a Nicotiana plant.
A method for enhancing the resistance of a non-Nicotiana plant to at least one species of Xanthomonas, Pseudomonas and/or Ralstonia, comprising:
- (a) introducing an exogenous polynucleotide encoding a polypeptide that is at least 90% identical to SEQ ID NO:
- 1 into a non-Nicotiana plant cell;
- (b) regenerating a transgenic non-Nicotiana plant from the non-Nicotiana plant cell;
- and
- (c) selecting said transgenic non-Nicotiana plant or a progeny of the same that contains the exogenous polynucleotide for resistance to Xanthomonas, Pseudomonas, and/or Ralstonia.
