What is the FLG22 Peptide?

The flg22 peptide is recognized as a pathogen-associated molecular pattern (PAMP) in plants. Its sequence is highly conserved across various bacterial species, making it a reliable trigger for innate immunity. The flg22 peptide is known to elicit specific innate immune responses in plants and has also been shown to be effective in both plants and algae. It is a peptide with its sequence derived from the flagellin N-terminus of *Pseudomonas aeruginosa*, and it is also found in other bacteria like *Bacillus thuringiensis* as the Flg22-Bt peptide.flg22 Peptideis a peptide with its sequence derived from the flagellin N-terminus of Pseudomonas aeruginosa and is known to elicit specific innate immune ...

Mechanism of Action and Significance in Plant Immunity

The primary mechanism by which the flg22 peptide functions is through its interaction with the plant cell surface receptor FLS2 (FLAGELLIN-SENSING2).flg22 Peptideis a peptide with its sequence derived from the flagellin N-terminus of Pseudomonas aeruginosa and is known to elicit specific innate immune ... Upon binding of flg22 to FLS2, a signaling cascade is initiated, leading to the activation of pattern-triggered immunity (PTI). This response is critical for plants to defend themselves against bacterial invasion. Research has demonstrated that FLS2 binds flg22 and initiates these signaling responses. The flg22 peptide is routinely used in laboratories to trigger PTI.

Studies have shown that flg22 can gain access to long-distance transport systems within the plant. Using biologically active, labeled peptides, researchers have established that flg22 moves to distal organs with the closest vascular connections. This movement suggests a systemic signaling capability, allowing plants to prime defenses throughout their tissues.This is 22 amino acids flagellinpeptideknown as flg2. It spans the core domain necessary for binding and biological activity in plant cells.
