Abstract
Pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI) describes the first events after pathogen invasion, whereby the plant identifies the presence of an invader and mounts a response. A race ensues in which the pathogen deploys its array of virulence molecules that act in opposition to host defence mechanisms and promote establishment of a pathogenic niche. Since the seminal work identifying the first pathogen receptor, FLAGELLIN-SENSING 2 (FLS2), the field has worked to define receptor complexes and downstream signalling pathways. This article describes recent progress in this area. In addition, many pathogen effectors target the PTI machinery. Thus, identifying PTI components as effector targets helps to validate those molecules as components of the defence machinery. As such, early molecular interactions are key to the outcome of infection. Indeed it is thought that nonhost resistance, in which most plants species are resistant to most pathogens, is likely to be a result of the PTI system
