摘要
Pathogen-associated molecular patterns(PAMPs)are recognized by host-encoded,cell-surface-localized,pattern-recognition receptors.In plants,pattern-recognition receptors consist of two kinds of proteins,the receptor-like kinases(RLKs)and the receptor-like proteins(RLPs).Compared with RLKs,RLPs lack an intracellular kinase domain,thus requiring co-receptors to initiate intracellular immune responses.PAMP recognition by RLKs with extracellular leucine-rich repeat(LRR)domains has been extensively studied,with structures of several PAMP-RLK pairs solved;however,the mechanism of how RLPs are activated is not well understood.
