Host pattern recognition receptor-mediated perception of microbe-associated
molecular patterns (MAMP) is a prerequisite for the initiation of antimicrobial
defenses in all multicellular organisms including plants. As metazoans, plants
have evolved immune receptors for the recognition of bacterial
lipopolysaccharides, flagellin and peptidoglycan. Here, I will report on the
identification of a plant peptidoglycan receptor complex mediating
peptidoglycan sensing and immunity to bacterial infection, and will discuss
convergent evolution of peptidoglycan recognition receptors across lineage
borders.
Immunity to bacterial infection is not only the result of microbial pattern
recognition, but may also be brought about upon recognition of host derived
damage-associated microbial patterns. Experimental evidence will be
presented for how a microbial pore-forming toxin resembling aquaporins
mediates microbial attack and plant immunity.
