Innate immunity, triggered after recognition of microbe-associated molecular patterns (MAMPs) by specific host receptors, is crucial for animals and plants. Lipopolysaccharide (LPS), covering the cell surface of Gram-negative bacteria, is a virulence factor shielding bacteria from hostile host environments and activates immune responses in animals and plants. LPS, in particular the lipid A moiety, is sensed as MAMP in mammals through multiple LPS receptors. Recently, we found that the bulb-type lectin S-domain-1 receptor-like kinase LORE (LipoOligosaccharide-specific Reduced Elicitation) mediates sensitive perception of Pseudomonas LPS in Arabidopsis. The lipid A moiety of Pseudomonas LPS alone is sufficient to induce immune responses.
