| Description | Elf18 is a peptide fragment of bacterial translation elongation factor Tu (EF-Tu). Elf18 can be recognized by plant pattern recognition receptors, thereby inducing an immune response. Elf18 can enhance plants' resistance to pathogens and can be used in research related to plant immune responses[1][2Elf18 is a peptide fragment of bacterial translation elongation factor Tu (EF-Tu).
