elf18
Elf18 is a peptide consisting of 18 conserved amino acids at the N-terminus of bacterial elongation factor Tu (EF-Tu), the most abundant bacterial protein.
As a microbe- or pathogen-associated molecular pattern (MAMP or PAMP), elf18 can trigger strong plant immune responses, such as cell-wall reinforcement by callose deposition, production of reactive oxygen species (ROS), and induction of numerous defense-related genes. However, unlike another PAMP flg22, which is perceived by most plants through FLS2 receptor, elf18 can be only perceived by Brassicaceae through EFR receptor.
At least in A. thaliana, elf18 can trigger mildly stronger immune responses than flg22.
