Transcriptional profile of AvrRpt2_EA-mediated resistance and susceptibility response to Erwinia amylovora in apple.

ABSTRACT: Most of the commercial apple cultivars are highly susceptible to fire blight, which is the most devastating bacterial disease affecting pome fruits. Resistance to fire blight is described especially in wild Malus accessions such as M. × robusta 5 (Mr5), but the molecular basis of host resistance response to the pathogen Erwinia amylovora is still largely unknown. The bacterial effector protein AvrRpt2_EA was found to be the key determinant of resistance response in Mr5. A wild type E. amylovora strain and the corresponding avrRpt2_EA deletion mutant were used for inoculation of Mr5 to induce resistance or susceptible response, respectively. By comparison of the transcriptome of both responses, 211 differentially expressed genes (DEGs) were identified. We found that heat
