Results. 2.1. rtnlb4 Mutants Were Recalcitrant to Agrobacterium-Mediated .... Derived from the highly conserved bacterial translation elongation factor Tu (EF-Tu), this short peptide fragment plays a vital role in triggering plant defense mechanisms. Specifically, the elf18 peptide represents the N-terminal 18 amino acids of EF-Tu, a region that has been identified as being specifically recognized by certain plant pattern recognition receptors.

Understanding the Mechanism of Elf18 Peptide Recognition

Research has elucidated that plant peptides like elf18 are recognized by plant pattern recognition receptors (PRRs).Specific ER quality control components required for ... In the case of elf18, the primary receptor identified in *Arabidopsis thaliana* is the EF-Tu receptor (EFR)Peptides: A synthetic step change. The EFR is a leucine-rich repeat receptor kinase (LRR-RK) that specifically binds to the N-acetylated peptide elf18. This binding event initiates a cascade of cellular responses, collectively known as the PAMP-triggered immunity (PTI). PTI is a fundamental layer of plant defense against a broad range of microbial pathogensArabidopsis thaliana Pattern Recognition Receptors for ....

The interaction between elf18 and EFR is a well-studied example of how plants detect conserved microbial molecules.作者：J Li·2009·被引用次数：322—EF-Tu and flagellin, and the derivedpeptides elf18and flg22, are recognized in Arabidopsis by the leucine-rich repeat receptor kinases (LRR-RK), EFR and FLS2, ... Unlike some other bacterial elicitors, elf18 is a water-soluble molecule and is relatively small in size compared to the EFR ectodomain, which possesses 21 LRRs.2015年1月23日—Notably, addition of the bacterial elicitors flg22 orelf18, both potent inducers of PTI, did not provoke an early onset of leaf senescence. This specific recognition highlights the evolutionary adaptation of plants to identify conserved structural motifs in bacterial proteins. The importance of this interaction is further underscored by studies demonstrating that transgenic expression of AtEFR in other plant families, such as Solanaceae, can confer elf18 responsiveness and broad-spectrum bacterial disease resistance.

The elf18 peptide acts as a potent inducer of plant defense responses.Arabidopsis EF‐Tu receptor enhances bacterial disease ... Upon perception by EFR, it triggers a signaling pathway that can involve various downstream effectors, including the induction of long noncoding RNA associated with defense, such as ELF18-INDUCED LONG NONCODING RNA 25. This suggests a complex regulatory network is activated by elf18 perception, extending beyond immediate cellular responses.

Furthermore, research has explored the role of elf18 in different plant species and under various conditions. For instance, while elf18 and its related peptides stimulate H2O2 generation in *Arabidopsis*, studies have shown that they do not induce this response in cultured rice cells, indicating species-specific recognition or signaling pathways.作者：T Furukawa·2014·被引用次数：137—In Brassicaceae species, EF-Tu and an N-acetylatedpeptidecomprising the first 18 amino acids of the N-terminus, termedelf18, are fully active as inducers of ...
