Innate immunity in plants: an arms race between pattern recognition receptors in plants and effectors in microbial pathogens.
For many years, research on a suite of plant defense responses that begin when plants are exposed to general microbial elicitors was underappreciated, for a good reason: There has been no critical experimental demonstration of their importance in mediating plant resistance during pathogen infection. Today, these microbial elicitors are named pathogen- or microbe-associated molecular patterns (P...
متن کاملPlants versus pathogens: an evolutionary arms race.
The analysis of plant-pathogen interactions is a rapidly moving research field and one that is very important for productive agricultural systems. The focus of this review is on the evolution of plant defence responses and the coevolution of their pathogens, primarily from a molecular-genetic perspective. It explores the evolution of the major types of plant defence responses including pathogen...
متن کاملPattern-recognition receptors in plant innate immunity.
Perception of pathogen-associated molecular patterns (PAMPs) constitutes the first layer of plant innate immunity and is referred to as PAMP-triggered immunity (PTI). For a long time, part of the plant community was sceptical about the importance of PAMP perception in plants. Genetic and biochemical studies have recently identified pattern-recognition receptors (PRRs) involved in the perception...
متن کاملPattern recognition receptors in innate immunity, host defense, and immunopathology.
Infection by pathogenic microbes initiates a set of complex interactions between the pathogen and the host mediated by pattern recognition receptors. Innate immune responses play direct roles in host defense during the early stages of infection, and they also exert a profound influence on the generation of the adaptive immune responses that ensue. An improved understanding of the pattern recogn...
متن کاملImmune Receptors and Co-receptors in Antiviral Innate Immunity in Plants
Plants respond to pathogens using an innate immune system that is broadly divided into PTI (pathogen-associated molecular pattern- or PAMP-triggered immunity) and ETI (effector-triggered immunity). PTI is activated upon perception of PAMPs, conserved motifs derived from pathogens, by surface membrane-anchored pattern recognition receptors (PRRs). To overcome this first line of defense, pathogen...
