MAMP (Microbe-Associated Molecular Pattern) triggered immunity in Plants [PDF]
Frontiers in Plant Science, 2013 Plants are sessile organisms that are under constant attack from microbes. They rely on both preformed defenses, and their innate immune system to ward of the microbial pathogens.

Host-induced bacterial cell wall decomposition mediates pattern-triggered immunity in Arabidopsis
eLife, 2014 Peptidoglycans (PGNs) are immunogenic bacterial surface patterns that trigger immune activation in metazoans and plants. It is generally unknown how complex bacterial structures such as PGNs are perceived by plant pattern recognition receptors (PRRs) and

Identification of Nicotiana benthamiana Genes Involved in Pathogen-Associated Molecular Pattern–Triggered Immunity [PDF]
Molecular Plant-Microbe Interactions, 2010 In order to identify components of pathogen-associated molecular pattern–triggered immunity (PTI) pathways in Nicotiana benthamiana, we conducted a large-scale forward-genetics screen using virus-induced gene silencing and a cell-death-based assay for ...

Multilayer regulatory landscape during pattern-triggered immunity in rice. [PDF]
Plant Biotechnol J, 2021 SummaryUpon fungal and bacterial pathogen attack, plants launch pattern‐triggered immunity (PTI) by recognizing pathogen‐associated molecular patterns (PAMPs) to defend against pathogens. Although PTI‐mediated response has been widely studied, a systematic understanding of the reprogrammed cellular processes during PTI by multi‐omics analysis is ...

The transcriptional landscape of Arabidopsis thaliana pattern-triggered immunity. [PDF]
Nat Plants, 2021 AbstractPlants initiate immunity upon recognition of a wide array of self and non-self molecular patterns. Whether plants tune their immune outputs to patterns of different biological origins or of different biochemical nature remains mostly unclear.

Pattern-triggered immunity against root-knot nematode infection: A minireview. [PDF]
Physiol Plant, 2022 AbstractPattern‐triggered immunity (PTI) is the basal level of defense a plant has against pathogens. In the case of root‐knot nematodes (RKN), PTI relies on the recognition of nematode‐associated molecular patterns (NAMPs) for activation. Nematodes have successfully overcome PTI many times by evolving effector proteins to combat PTI responses.

Molecular mechanisms of early plant pattern-triggered immune signaling [PDF]
Molecular Cell, 2021 All eukaryotic organisms have evolved sophisticated immune systems to appropriately respond to biotic stresses. In plants and animals, a key part of this immune system is pattern recognition receptors (PRRs). Plant PRRs are cell-surface-localized receptor kinases (RKs) or receptor proteins (RPs) that sense microbe- or self-derived molecular patterns to

Signaling Mechanisms in Pattern-Triggered Immunity (PTI) [PDF]
Molecular Plant, 2015 In nature, plants constantly have to face pathogen attacks. However, plant disease rarely occurs due to efficient immune systems possessed by the host plants. Pathogens are perceived by two different recognition systems that initiate the so-called pattern-triggered immunity (PTI) and effector-triggered immunity (ETI), both of which are accompanied by a

Dynamic enhancer transcription associates with reprogramming of immune genes during pattern triggered immunity in Arabidopsis. [PDF]
BMC Biol, 2022 Abstract Background Enhancers are cis-regulatory elements present in eukaryote genomes, which constitute indispensable determinants of gene regulation by governing the spatiotemporal and quantitative expression dynamics of target genes, and are involved in multiple life processes, for instance during development and ...

Balanced callose and cellulose biosynthesis in Arabidopsis quorum-sensing signaling and pattern-triggered immunity. [PDF]
Plant Physiol, 2023 Abstract The plant cell wall (CW) is one of the most important physical barriers that phytopathogens must conquer to invade their hosts. This barrier is a dynamic structure that responds to pathogen infection through a complex network of immune receptors, together with CW-synthesizing and CW-degrading enzymes.
