AvrPtoB Targets the LysM Receptor Kinase CERK1 to Promote Bacterial Virulence on Plants
Plant innate immunity relies on a set of pattern recognition receptors (PRRs) that respond to ligands known as pathogen-associated molecular patterns (PAMPs). To overcome such immunity, phytopathogenic bacteria deliver virulence molecules called effector proteins into the plant cell that collectively promote pathogenesis. The vast majority of PRRs controlling PAMP-triggered immunity (PTI) and t...
متن کاملCERK1, a LysM receptor kinase, is essential for chitin elicitor signaling in Arabidopsis.
Chitin is a major component of fungal cell walls and serves as a microbe-associated molecular pattern (MAMP) for the detection of various potential pathogens in innate immune systems of both plants and animals. We recently showed that chitin elicitor-binding protein (CEBiP), plasma membrane glycoprotein with LysM motifs, functions as a cell surface receptor for chitin elicitor in rice. The pred...
متن کاملThe Arabidopsis CERK1‐associated kinase PBL27 connects chitin perception to MAPK activation
Perception of microbe-associated molecular patterns by host cell surface pattern recognition receptors (PRRs) triggers the intracellular activation of mitogen-activated protein kinase (MAPK) cascades. However, it is not known how PRRs transmit immune signals to MAPK cascades in plants. Here, we identify a complete phospho-signaling transduction pathway from PRR-mediated pathogen recognition to ...
متن کاملThe LysM - RLK CERK 1 is a major chitin binding protein in Arabidopsis thaliana and subject to chitin - induced phosphorylation
Plants detect potential pathogens by sensing microbe associated molecular patterns via pattern recognition receptors. In the dicot model plant Arabidopsis, the Lysin Motif (LysM) containing Chitin Elicitor Receptor Kinase 1 (CERK1) has been shown to be essential for perception of the fungal cell wall component chitin and for resistance to fungal pathogens. Recent in vitro studies with CERK1 pro...
متن کاملArabidopsis lysin-motif proteins LYM1 LYM3 CERK1 mediate bacterial peptidoglycan sensing and immunity to bacterial infection.
Recognition of microbial patterns by host pattern recognition receptors is a key step in immune activation in multicellular eukaryotes. Peptidoglycans (PGNs) are major components of bacterial cell walls that possess immunity-stimulating activities in metazoans and plants. Here we show that PGN sensing and immunity to bacterial infection in Arabidopsis thaliana requires three lysin-motif (LysM) ...
