AtLYK4 is the major chitin receptor in Arabidopsis with N-glycosylation and ligand-interacting residues orchestrating chitin perception.

Fungi, arthropods, and nematodes are chitin-containing organisms that cause severe damage to crop production. Plants can sense chitin to activate immunity against these invaders. In Arabidopsis thaliana (Arabidopsis), the lysin motif-containing recep…
