LYK1 — Arabidopsis thaliana

Summary

AT3G21630 (LYK1, also known as CERK1) in Arabidopsis thaliana encodes a non-specific serine/threonine protein kinase with LysM domains. The gene is associated with plant immunity, including chitin-induced immune signaling and defense responses against bacterial and fungal pathogens. It has been linked to traits such as freezing stress response, drought tolerance, abscisic acid sensitivity, grain size, seed set, and bacterial blight disease resistance. The encoded protein localizes to various cellular compartments including the signal peptidase complex, chloroplast thylakoid membrane, and extracellular matrix. Studies of related genes in other species connect the LYK family to wheat fusarium head blight response and defective systemic acquired resistance in tomato.
