Pattern-triggered immunity (PTI) mediated strategies to deploy broad-spectrum pathogen resistance in crops: a conceptual representation. (A) Perception of MAMPs and/or DAMPs by PRRs activates the PTI response. Adapted, virulent pathogens deliver effectors to suppress PTI, rendering wild-type plants susceptible to infection. (B) Interfamily or interspecies transfer of foreign PRRs improves MAMPs recognition and further enhances PTI. Host co-evolved pathogens are unlikely to possess effectors targeting PRRs from other plant species. (C) Heterologous expression of PTI enhancers/positive regulators boosts PTI signaling. Effectors may thus not be sufficient anymore to efficiently repress PTI.
