Protein phosphatase AP2C1 negatively regulates basal resistance and defense responses to Pseudomonas syringae [PDF]

, 2017
Mitogen-activated protein kinases (MAPKs) mediate plant immune responses to pathogenic bacteria. However, less is known about the cell autonomous negative regulatory mechanism controlling basal plant immunity. We report the biological role of Arabidopsis

Do guard cells have single or multiple defense mechanisms in response to flg22? [PDF]

Physiologia Plantarum
AbstractBacterial flagellin (flg22) induces rapid and permanent stomatal closure. However, its local and systemic as well as tissue‐ and cell‐specific effects are less understood. Our results show that flg22 induced local and systemic stomatal closure in intact tomato plants, which was regulated by reactive oxygen‐ and nitrogen species, and also ...

Arabidopsis SBT5.2 and SBT1.7 subtilases mediate C-terminal cleavage of flg22 epitope from bacterial flagellin

Nature Communications
Plants initiate specific defense responses by recognizing conserved epitope peptides within the flagellin proteins derived from bacteria. Proteolytic cleavage of epitope peptides from flagellin by plant apoplastic proteases is thought to be crucial for ...

Expression patterns of FLAGELLIN SENSING 2 map to bacterial entry sites in plant shoots and roots [PDF]

, 2016
Expression of the flagellin receptor FLS2 is regulated in a cell/tissue-specific and stress-induced manner that correlated with sites of bacterial infection.

In roots of Arabidopsis thaliana, the damage-associated molecular pattern AtPep1 is a stronger elicitor of immune signalling than flg22 or the chitin heptamer.

PLoS ONE, 2017
Plants interpret their immediate environment through perception of small molecules. Microbe-associated molecular patterns (MAMPs) such as flagellin and chitin are likely to be more abundant in the rhizosphere than plant-derived damage-associated ...

Phosphorylation Dynamics in a flg22-Induced, G Protein–Dependent Network Reveals the AtRGS1 Phosphatase

Molecular & Cellular Proteomics
The microbe-associated molecular pattern flg22 is recognized in a flagellin-sensitive 2-dependent manner in root tip cells. Here, we show a rapid and massive change in protein abundance and phosphorylation state of the Arabidopsis root cell proteome in WT and a mutant deficient in heterotrimeric G-protein-coupled signaling.

Determination of AtSCD1 mRNA and protein levels in the temperature sensitive mutant scd1-1 [PDF]

, 2008
only availablePlant cells defend themselves against bacterial infection by first detecting bacterial flagellin outside the cell and then initiating defense responses within the cell.

Repression of the auxin response pathway increases Arabidopsis susceptibility to necrotrophic fungi

, 2008
In plants, resistance to necrotrophic pathogens depends on the interplay between different hormone systems, such as those regulated by salicylic acid (SA), jasmonic acid (JA), ethylene, and abscisic acid.

Quo vadis, Pep? Plant elicitor peptides at the crossroads of immunity, stress, and development [PDF]

, 2017
Peps were discovered as endogenous peptides triggering plant defence. Here we additionally highlight first studies showing their connection to plant stress resistance and ...

STER1, a novel receptor-like kinase, functions in MAMP signalling in Arabidopsis

, 2011
S. epidermidis has long been recognized as an important opportunistic pathogen accounting for the majority of nosocomial infections alongside S. aureus. However, in spite of this, our understanding of the S.
