The @entity523 Mi-1 gene confers resistance to three species of root-knot @entity2199 and @entity415 aphid. We studied changes in expression of @entity7214 (JA)- and @entity3785 (SA)-dependent defense genes in response to @entity415 and green @entity2486 aphids. We determined changes in three PR proteins, @entity56604 and @entity70498 transcripts, locally and systemically in both compatible and incompatible interactions in @entity523 . Transcripts for PR-1 were detected earlier and accumulated to higher levels in the incompatible than in the compatible @entity415 aphid/ @entity523 interactions. The transcript profiles of the other genes were similar in compatible compared with incompatible interactions. @entity45424 and @entity45425 RNAs were detected early and transiently in both compatible and incompatible interactions. In @entity523 plants containing Mi-1, systemic expression of PR-1 and GluB was detected in both compatible and incompatible interactions at 48 h after infestations with either aphid. These results suggest that aphid feeding involves both SA and JA/ @entity1786 plant defense signaling pathways and that Mi-1-mediated resistance might involve a SA-dependent signaling pathway. @entity415 aphid feeding generated reactive @entity26 species in both compatible and incompatible interactions. However, a hypersensitive response was absent in the Mi-1-mediated resistance response to @entity415 aphids. Reciprocal grafting experiments revealed that resistance is cell autonomous, and local expression of Mi-1 is required for Mi-1-mediated resistance against the @entity415 aphid.
