Plant Surface Receptors Recognizing Microbe-Associated Molecular Patterns

Journal of Plant Biology, 2018
As sessile, plants are inevitably exposed to environmental threats including pathogens. Due to the lack of mobile immune cells, plants solely depend on the innate immune system to defend against pathogens. The first layer of pathogen detection in plant immunity is to recognize microbe-associated molecular patterns (MAMPs) that compose structural or ...

Microbe-associated molecular patterns in innate immunity: Extraction and chemical analysis of gram-negative bacterial lipopolysaccharides.

Methods in enzymology, 2010
Bacterial lipopolysaccharides (LPSs) are the major component of the outer membrane of Gram-negative bacteria. They have a structural role since they contribute to the cellular rigidity by increasing the strength of cell wall and mediating contacts with the external environment that can induce structural changes to allow life in different conditions ...

A renaissance of elicitors: perception of microbe-associated molecular patterns and danger signals by pattern-recognition receptors.

Annual Review of Plant Biology, 2009
Microbe-associated molecular patterns (MAMPs) are molecular signatures typical of whole classes of microbes, and their recognition plays a key role in innate immunity. Endogenous elicitors are similarly recognized as damage-associated molecular patterns (DAMPs).

Xanthomonas citri pv. citri Pathotypes: LPS Structure and Function as Microbe‐Associated Molecular Patterns [PDF]

open access: possibleChemBioChem, 2017
AbstractXanthomonas citri pv. citri is the pathogen responsible for Asiatic citrus canker, one of the most serious citrus diseases worldwide. The lipopolysaccharide (LPS) molecule has been demonstrated to be involved in X. citri pv. citri virulence.

Characterizing the Immune-Eliciting Activity of Putative Microbe-Associated Molecular Patterns in Tomato.

Methods in molecular biology, 2017
Detection of conserved microbe-associated molecular patterns (MAMPs), such as bacterial flagellin, is the first line of active defense in plants against pathogenic invaders. Successful pathogens must subvert this immune response to grow to high population density and cause disease.

Chapter 3:Lipopolysaccharides as Microbe-associated Molecular Patterns: A Structural Perspective

, 2015
The lipopolysaccharide (LPS) macromolecule is the major constituent of the external leaflet of the Gram-negative outer membrane, exerting a plethora of biological activities in animals and plants. Among all, it represents a defensive barrier which helps bacteria to resist antimicrobial compounds and external stress factors and is involved in most ...

Bacterial cell wall macroamphiphiles: pathogen-/microbe-associated molecular patterns detected by mammalian innate immune system.

Biochimie, 2013
Innate immune system is the first line of host defense against invading microorganisms. It relies on a limited number of germline-encoded pattern recognition receptors that recognize conserved molecular structures of microbes, referred to as pathogen-/microbe-associated molecular patterns (PAMPs/MAMPs). Bacterial cell wall macroamphiphiles, namely Gram-

Microbe associated molecular patterns from rhizosphere bacteria trigger germination and Papaver somniferum metabolism under greenhouse conditions.

Plant Physiology and Biochemistry, 2014
Ten PGPR from different backgrounds were assayed on Papaver somniferum var. Madrigal to evaluate their potential as biotic elicitors to increase alkaloid content under the rationale that some microbe associated molecular patterns (MAMPs) are able to trigger plant metabolism.

Analysis of Microbe-Associated Molecular Pattern-Responsive Synthetic Promoters with the Parsley Protoplast System.

Methods in molecular biology, 2016
Plants recognize pathogens by microbe-associated molecular patterns (MAMPs) and subsequently induce an immune response. The regulation of gene expression during the immune response depends largely on cis-sequences conserved in promoters of MAMP-responsive genes.
