Interpretive Summary: Pattern triggered immunity (PTI) is a basic defense response found in all higher plants. It is generally regarded as highly conserved across species. While this is generally true, there are important differences within and across species in how PTI is induced and in the strength and quality of the response. We discuss the research in this area and its potential implications.

Technical Abstract: The pattern-triggered immunity (PTI) response is triggered at the plant cell surface by the recognition of microbe-derived molecules known as microbe-or pathogen-associated molecular patterns or molecules derived from compromised host cells called damage-associated molecular patterns. Membrane-localized receptor proteins, known as pattern recognition receptors, are responsible for this recognition. Although much of the machinery of PTI is conserved, natural variation for the PTI response exists within and across species with respect to the components responsible for pattern recognition, activation of the response, and the strength of the response induced. This review describes what is known about this variation. We discuss how variation in the PTI response can be measured and how this knowledge might be utilized in the control of plant disease and in developing plant varieties with enhanced disease resistance.
