Salmonella enterica Flagellin Is Recognized via FLS2 and Activates PAMP-Triggered Immunity in Arabidopsis thaliana [PDF]
Molecular Plant, 2014 Infections with Salmonella enterica belong to the most prominent causes of food poisoning and infected fruits and vegetables represent important vectors for salmonellosis. Recent evidence indicates that plants recognize S. enterica and raise defense responses. Nonetheless, the molecular mechanisms controlling the interaction of S.

Immune responses to flagellin have been evolutionarily conserved between plants and animals. In Arabidopsis , FLS2, a leucine-rich repeat (LRR) domain containing serine-threonine transmembrane kinase binds bacterial flagellin and mediates signals, culminating in a defensive response.

Autoimmunity and hyperactivation of immune responses by HAE-FLS2 chimera
Journal of Plant PhysiologyPlants employ cell surface receptors to perceive extracellular signals and initiate appropriate cellular responses, thereby regulating diverse physiological processes. The well-characterized leucine-rich repeat receptor-like kinases (LRR-RLK) type receptor FLAGELLIN-SENSITIVE 2 (FLS2) functions as a pattern recognition receptor (PRR) that specifically ...

Structural and biochemical basis of FLS2-mediated signal activation and transduction in rice
Plant CommunicationsThe receptor-like kinase FLAGELLIN-SENSITIVE 2 (FLS2) functions as a bacterial flagellin receptor localized on the cell membrane of plants. In Arabidopsis, the co-receptor BRI1-ASSOCIATED RECEPTOR KINASE 1 (BAK1) cooperates with FLS2 to detect the flagellin epitope flg22, resulting in formation of a signaling complex that triggers plant defense ...

Mapping FLS2 function to structure: LRRs, kinase and its working bits
Protoplasma, 2012The plasma membrane-localised FLAGELLIN SENSING 2 (FLS2) receptor is an important component of plant immunity against potentially pathogenic bacteria, acting to recognise the conserved flg22 peptide of flagellin. FLS2 shares the common structure of transmembrane receptor kinases with a receptor-like ectodomain composed of leucine-rich repeats (LRR) and

Conserved exitrons of FLAGELLIN-SENSING 2 (FLS2) across dicot plants and their functions
Plant Science, 2020The alternative splicing of pattern recognition receptor genes regulates immune signalling in mammals, but in plants its role is still unknown. Here, we detected alternatively spliced introns (exitrons) in the first annotated exons of FLAGELLIN-SENSING 2 (FLS2) genes in all the examined dicot plants across nine families. The 5' splice site (SS) regions

Summary The flagellin receptor of Arabidopsis, At‐FLAGELLIN SENSING 2 (FLS2), has become a model for mechanistic and functional studies on plant immune receptors. Responses to flagellin or its active epitope flagellin 22 (flg22) have been extensively studied in Arabidopsis leaves.

Structural Basis for flg22-Induced Activation of the Arabidopsis FLS2-BAK1 Immune Complex
Science, 2013First Defense In defense against bacterial infection, plants carry a cell-surface receptor, known as FLS2, that can bind to a fragment of bacterial flagellin and trigger defense responses. Y. Sun et al. (p. 624 , published online 10 October)

Summary The plasma membrane (PM)‐localized receptor kinase FLAGELLIN SENSING 2 (FLS2) recognizes bacterial flagellin or its immunogenic epitope flg22, and initiates microbe‐associated molecular pattern‐triggered immunity, which inhibits infection by bacterial pathogens. The localization, abundance and activity of FLS2 are under dynamic control. Here,

An overexcited plant immunoreceptor: a hybrid FLS2 receptor that is active without flagellin
2022Perception of bacterial flagellin by the receptor kinase AtFLS2 is a classic model for studying the molecular functioning of plant immunoreceptors. Although FLS2 receptors with a conserved ectodomain consisting of 28 leucine-rich repeats (LRRs) occur in a broad range of plant species, these FLS2 homologs display species-specific characteristics with ...
