Abstract

Abstract:

Plants rely on pattern recognition receptors (PRRs) to perceive conserved signatures of pathogenic microorganisms. This recognition triggers the first layer of immunity, which consists of non-host resistance against various microorganisms and generates basal resistance. Arabidopsis FLS2 is the first PRR identified in plants that recognizes bacterial flagellin. A large number of studies on FLS2 provide examples and basis for future studies of other PRRs, and they promote the establishment and development of the plant immune theory. In the present study, we reviewed the discovery and naming process of FLS2, its structure and function, the process of activation, related components, mechanism of regulation, interaction with effectors, and phylogeny in angiosperms. We also analyzed the technical problems in protein contamination and C-terminal tags accompanying FLS2 research, and we introduced the prospect of breeding plants with broad-spectrum and durable resistance to disease by genetic transformation with plant pattern recognition receptor genes.

Key words: plant pattern recognition receptor, plant immune system, FLS2, regulation
