R, resistant; S, susceptible.

  • a The localities of these accessions are indicated on the map in Figure 1.

  • b The recognition specificity of the alleles isolated from these ecotypes to these three P. parasitica strains was tested by allelic complementation using stable transgenics as described in Bittner-Eddy et al. (2000).

  • c Although these ecotypes were resistant to the corresponding pathogen isolate, the RPP13 allele isolated from these individuals did not confer this pathogen recognition. Other loci in these plants are implicated for conferring resistance to these isolates.
