Effects of Harpin and Flg22 on Growth Enhancement and Pathogen Defense in Cannabis sativa Seedlings [PDF]
Pathogen-associated molecular patterns, PAMPs, are a diverse group of molecules associated with pathogenic microbes and are known to activate immune response and in some cases enhance growth in plants.

NPR1 is Instrumental in Priming for the Enhanced flg22-induced MPK3 and MPK6 Activation [PDF]
Pathogen-associated molecular patterns (PAMPs) activate mitogen-activated protein kinases (MAPKs), essential components of plant defense signaling. Salicylic acid (SA) is also central to plant resistance responses, but its specific role in regulation of ...

Xylem Sap Proteome Analysis Provides Insight into Root–Shoot Communication in Response to flg22 [PDF]
Xylem sap proteomics provides crucial insights into plant defense and root-to-shoot communication. This study highlights the sensitivity and reproducibility of xylem sap proteome analyses, using a single plant per sample to track over 3000 proteins in ...

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

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

S-Nitroso-Proteome Revealed in Stomatal Guard Cell Response to Flg22 [PDF]
Nitric oxide (NO) plays an important role in stomata closure induced by environmental stimuli including pathogens. During pathogen challenge, nitric oxide (NO) acts as a second messenger in guard cell signaling networks to activate downstream responses leading to stomata closure.

Flg22-induced Ca2+ increases undergo desensitization and resensitization [PDF]
AbstractThe flagellin epitope flg22, a pathogen‐associated molecular pattern (PAMP), binds to the receptor‐like kinase FLAGELLIN SENSING2 (FLS2), and triggers Ca2+ influx across the plasma membrane (PM). The flg22‐induced increases in cytosolic Ca2+ concentration ([Ca2+]i) (FICA) play a crucial role in plant innate immunity.

Light-dependent expression of flg22-induced defense genes in Arabidopsis [PDF]
Chloroplasts have been reported to generate retrograde immune signals that activate defense gene expression in the nucleus. However, the roles of light and photosynthesis in plant immunity remain largely elusive.

MEKK1 Is Required for flg22-Induced MPK4 Activation in Arabidopsis Plants [PDF]
Abstract The Arabidopsis (Arabidopsis thaliana) gene MEKK1 encodes a mitogen-activated protein kinase kinase kinase that has been implicated in the activation of the map kinases MPK3 and MPK6 in response to the flagellin elicitor peptide flg22.

Proteobacteria Contain Diverse flg22 Epitopes That Elicit Varying Immune Responses in Arabidopsis thaliana [PDF]
Bacterial flagellin protein is a potent microbe-associated molecular pattern. Immune responses are triggered by a 22-amino-acid epitope derived from flagellin, known as flg22, upon detection by the pattern recognition receptor FLAGELLIN-SENSING2 (FLS2 ...
