Plant Immunity Triggered by Microbial Molecular Signatures

Plant immunity triggered by microbial molecular signatures.

Pathogen/microbe-associated molecular patterns (PAMPs/MAMPs) are recognized by host cell surface-localized pattern-recognition receptors (PRRs) to activate plant immunity. PAMP-triggered immunity (PTI) constitutes the first layer of plant immunity that restricts pathogen proliferation. PTI signaling components often are targeted by various Pseudomonas syringae virulence effector proteins, resul...

Plant innate immunity: perception of conserved microbial signatures.

Plants and animals sense conserved microbial signatures through receptors localized to the plasma membrane and cytoplasm. These receptors typically carry or associate with non-arginine-aspartate (non-RD) kinases that initiate complex signaling networks cumulating in robust defense responses. In plants, coregulatory receptor kinases have been identified that not only are critical for the innate ...

Molecular mechanisms of autoimmunity triggered by microbial infection

Autoimmunity can be triggered by microbial infection. In this context, the discovery of Toll-like receptors (TLRs) provides new insights and research perspectives. TLRs induce innate and adaptive antimicrobial immune responses upon exposure to common pathogen-associated molecules, including lipopeptides, lipopolysaccharides, and nucleic acids. They also have the potential, however, to trigger a...
