摘要：
In tomato, resistance to Pseudomonas syringae pv. tomato (Pst) strains expressing the avirulence gene avrPto requires the presence of at least two host genes, designated Pto and Prf. Here we report that Prf encodes a protein with leucine-zipper, nucleotide-binding, and leucine-rich repeat motifs, as are found in a number of resistance gene products from other plants. prf mutant alleles (4) were found to carry alterations within the Prf coding sequence. A genomic fragment containing Prf complemented a prf mutant tomato line both for resistance to Pst strains expressing avrPto and for sensitivity to the insecticide Fenthion. Prf resides in the middle of the Pto gene cluster, 24 kb from the Pto gene and 500 bp from the Fen gene.
