To distinguish between “self” and “nonself” during pathogen infection, plants possess pattern recognition receptors (PRRs) that perceive microbe-associated molecular patterns (MAMPs) which are conserved among a specific class of microorganisms (such as chitin for fungi, flagella for bacteria) but are absent in the host.

Perception of MAMPs or DAMPs by cell surface PRRs is called Pathogen Triggered Immunity

#Unit 6. System Physiology – Plant

Perception of MAMPs or DAMPs by cell surface PRRs initiates a localized basal defense response called MAMP triggered immunity which inhibits the growth and activity of nonadapted pathogens or pests.

When an Arabidopsis leaf is exposed to bacteria on the leaf surface, or to the MAMP flg22, the stomatal apertures closed by LRR receptor-like kinase FLS2, as well as a heterotrimeric G protein.

Flg22 also activates NADPH oxidases for the production of ROS are encoded by 10 respiratory burst oxidase homolog (Atrboh) genes. Two of the proteins, Atrboh D and F, are required
