Arabidopsis glycosylphosphatidylinositol-anchored protein LLG1 associates with and modulates FLS2 to regulate innate immunity.

ABSTRACT: Plants detect and respond to pathogen invasion with membrane-localized pattern recognition receptors (PRRs), which recognize pathogen-associated molecular patterns (PAMPs) and activate downstream immune responses. Here we report that Arabidopsis thaliana LORELEI-LIKE GPI-ANCHORED PROTEIN 1 (LLG1), a coreceptor of the receptor-like kinase FERONIA, regulates PRR signaling. In a forward genetic screen for suppressors of enhanced disease resistance 1 (edr1), we identified the point mutation llg1-3, which suppresses edr1 disease resistance but does not affect plant growth and development. The llg1 mutants show enhanced susceptibility to various virulent pathogens, indicating that LLG1 has an important role in plant immunity. LLG1 constitutively associat
