Flagellin is the structural protein which forms the major portion of bacterial flagella filaments. The N- and C- terminals of flagellin are highly conserved regions, whereas the central core can vary greatly between bacterial species. Flagellin 22 (flg22) is the most conserved stretch of amino acids across bacterial species and is located towards the N-terminal of flagellin.

Flg22 is a potent elicitor of plant immune responses and is recognised in plants by the membrane bound leucine-rich repeat-receptor kinase FLAGELLIN SENSITIVE 2 (FLS2). Flg22 induces defence gene expression to trigger both local and systemic immune responses and is thus widely used in plant defence studies.

Truncated flagellin 22 (flg22-Δ2) represents amino acids 1-20 of flg22. It is a strong and selective agonist of tomato FLS2, with weak agonist activity towards Arabidopsis FLS2 even at high concentrations.
