Research has established that flg22 is an effective elicitor not only in plants but also in algae.Flg22 The 22 amino acids flagellin peptide is a well-characterized fragment of flagellin, originating from the N-terminus of various bacterial species, including *Pseudomonas aeruginosa* and *Bacillus thuringiensis* (in the case of the Flg22-Bt peptide)Flagelin22. The conserved nature of this 22-amino acid sequence across different bacterial strains underscores its fundamental role in microbial recognition. The flg22 peptide sequence is crucial for its biological activity, enabling it to bind to specific plant receptors.flg22 Peptide

Mechanism of Action and Plant Immunity

The primary mechanism by which the flg22 peptide functions is through its interaction with the plant's pattern recognition receptor, FLAGELLIN SENSING2 (FLS2). FLS2 renders plant cells responsive to even subnanomolar concentrations of flg22.Leaf disks from WT plants were incubated with 100 nMflg22 peptideor flagellin protein. ROS production was measured every 30 s over 60 min. Values represent ... Upon binding of the flg22 peptide to FLS2, a complex signaling pathway is initiated, leading to the activation of pattern-triggered immunity (PTI). This immune response can manifest in various ways, including the production of reactive oxygen species (ROS), the deposition of callose to reinforce cell walls, and the activation of mitogen-activated protein kinase (MAPK) signaling pathways. These responses collectively help the plant to defend itself against invading pathogens.

Studies have demonstrated that flg22 peptides from different bacterial groups can elicit varying degrees of immune response. For instance, Flg22 peptides of the γ- and β-Proteobacteria have been shown to trigger strong oxidative bursts, while those from other proteobacterial classes may elicit different responses. The proteolytic release of the flg22 peptide from the flagellin protein requires precise cleavage at both the N- and C-termini of the 22-amino acid epitope, highlighting the specific enzymatic processes involved in generating this immunogenic molecule.

Systemic Signaling and Research Applications
