N-3-oxo-hexadecanoyl-L-Homoserine lactone is an unusual, substituted, long-chain N-acyl-homoserine lactone (AHL) produced by some bacteria, including strains of
Agrobacterium vitis and
Pseudomonas.
1,2 Like other AHLs, this C16-containing form is thought to be involved in quorum sensing. Substituted, long-chain AHLs, including N-3-oxo-tetradecanoyl-L-homoserine lactone , prime for systemic acquired resistance to pathogen attack in plants.
