Another interesting work included in this topic focuses on the activation of the plant immunity by a pathogen detection system known as pattern-triggered immunity (PTI) response (Huang and Zimmerli, 2014). This system relies on the accurate detection of pathogen-or microbe-associated molecular patterns by pattern-recognition receptors (PRRs). Resistance is the rule in the majority of plants. Huang and Zimmerli suggest that the reinforcement of PTI through genetic engineering may generate crops with broad-spectrum field resistance (Huang and Zimmerli, 2014).
