<i>CERK1</i> is required for chitin-triggered reactive oxygen species generation in melon and is broadly conserved in cucurbits.

ABSTRACT: CHITIN ELICITOR RECEPTOR KINASE 1 (CERK1), originally identified in Arabidopsis thaliana, encodes a pattern recognition receptor that perceives the fungal cell wall component called chitin to activate immune responses, including the production of reactive oxygen species (ROS) against fungal pathogens. Functional CERK1 orthologs have been identified in plants, such as tomato, rice, and wheat. However, the knowledge of chitin-triggered immunity in Cucurbitaceae plants is currently limited. This study revealed that chitin triggers ROS generation in melon (Cucumis melo) and cucumber (Cucumis sativus), indicating that chitin is recognized by cucurbits. A subsequent homology search using the Arabidopsis CERK1 sequence identified CERK1 ortholog candidates of mel
