Prf protein and nucleic acid sequences: compositions and methods for plant pathogen resistance

摘要

The Prf gene of tomato has been cloned and analyzed. Prf encodes a protein with leucine-rich repeat, nucleotide binding, and leucine zipper motifs, identifying it as a member of the resistance gene class that includes RPS2, RPM1, N and L6. When expressed in transgenic plants, Prf confers Fenthion sensitivity and resistance to a wide variety of phytopathogens, including not only Pseudomonas syringae but also unrelated pathogens such as Xanthomonas campestris.
