Plants, 2022 Pathogen associated molecular pattern (PAMP) triggered immunity (PTI) is the first line of plant defense. We hypothesized that the absence of pattern recognition receptors (PRRs) in plants could influence the rhizosphere microbiome.

Mycosphaerella graminicola LysM Effector-Mediated Stealth Pathogenesis Subverts Recognition Through Both CERK1 and CEBiP Homologues in Wheat [PDF]
Molecular Plant-Microbe Interactions, 2014 Fungal cell-wall chitin is a well-recognized pathogen-associated molecular pattern. Recognition of chitin in plants by pattern recognition receptors activates pathogen-triggered immunity (PTI).

Analysis of CERK1 ectodomain shedding and the role of XLG2 in cerk1-4 cell death execution [PDF]
, 2022 Conserved microbial signatures are perceived via plasma membrane localized pattern recognition receptors (PRRs). In Arabidopsis, perception of the fungal cell wall component chitin requires the LysM receptor-like kinase CERK1. CERK1 is post-translationally modified to release a soluble ectodomain derivative into the apoplast. The ectodomain fragment is

The LysM receptor kinase CERK1 mediates bacterial perception in Arabidopsis [PDF]
Plant Signaling & Behavior, 2009 Plants use pattern recognition receptors (PRRs) to perceive pathogen-associated molecular pattern (PAMPs) and initiate defence responses. PAMP-triggered immunity (PTI) plays an important role in general resistance, and constrains the growth of most microbes on plants. Despite the importance of PRRs in plant immunity, the vast majority of them remain to

AvrPtoB Targets the LysM Receptor Kinase CERK1 to Promote Bacterial Virulence on Plants [PDF]
Current Biology, 2009 Plant innate immunity relies on a set of pattern recognition receptors (PRRs) that respond to ligands known as pathogen-associated molecular patterns (PAMPs). To overcome such immunity, phytopathogenic bacteria deliver virulence molecules called effector proteins into the plant cell that collectively promote pathogenesis.

Cell death signaling in the Arabidopsis chitin receptor mutant cerk1-4 [PDF]
, 2023 Plant surface immunity is mediated by pattern recognition receptors (PRRs) that recognize con-served molecules derived from microorganisms. In Arabidopsis, CERK1 is the main component of the receptor complex that binds chitin and transduces the signal intracellularly (Miya et al., 2007; Petutschnig et al., 2010; Wan et al., 2008).

Characterization of Populus x canescens LysM Receptor-Like Kinases CERK1-1 and CERK1-2 and their Role in Chitin Signaling [PDF]
, 2022 Pappeln sind als ein Modell-Organismus für die Forschung an Bäumen etabliert. Populus trichocarpa war die erste vollständig sequenzierte Baumart. Trotzdem werden im Labor häufig andere Pappelarten für Experimente verwendet, da Populus trichocarpa nur schwer transformierbar ist.

Arabidopsis lysin-motif proteins LYM1 LYM3 CERK1 mediate bacterial peptidoglycan sensing and immunity to bacterial infection [PDF]
Proceedings of the National Academy of Sciences, 2011 Recognition of microbial patterns by host pattern recognition receptors is a key step in immune activation in multicellular eukaryotes. Peptidoglycans (PGNs) are major components of bacterial cell walls that possess immunity-stimulating activities in metazoans and plants.

Investigation of upstream and downstream events in CERK1-mediated signaling in plant immunity [PDF]
, 2015 As one part of a two-tiered pathogen-detection system in plants, PTI is not only sufficient to ward off most microbes, but also contributes to basal immunity during infection. Although PGN and the LYM1-LYM3-CERK1 receptor complex have been identified as one PAMP-PRR pair in Arabidopsis, upstream and downstream events of PGN perception remain elusive ...

Analysis of the role of Arabidopsis extra-large G protein 2 in cerk1-4-dependent cell death signalling [PDF]
, 2022 Pflanzen nehmen Mikroben-assoziierte molekulare Muster (MAMPs) mit Hilfe von sogenannten Muster-erkennenden Rezeptoren (PRRs) an der Zellmembran wahr, wodurch eine Immunantwort ausgelöst wird. Heterotrimere G-Proteine sind an der intrazellulären Signaltransduktion beteiligt und sind aus einer Gα-Untereinheit und einer Gβγ-Untereinheit zusammengesetzt ...
