Technical Abstract: Systemic acquired resistance (SAR) is a natural plant defense mechanism shown to be effective against a broad range of pathogens and has been best characterized in tobacco and Arabidopsis. As a step towards evaluating the potential to use SAR for disease control in potato, the effectiveness of different inducers of SAR, including salicylic acid, BTH and harpin was examined. The timing and magnitude of defense gene activation in response to these compounds was monitored in roots, stems and leaves. The ability of SAR inducers to give resistance against various potato pathogens was evaluated and correlated with the efficacy of denfense gene induction.
