RLK — Cucumis melo

Summary

MELO3C033530.2 (RLK) on melon chromosome 10 encodes a transmembrane receptor serine/threonine kinase with a legume lectin domain, classified as an L-type lectin receptor kinase. It exhibits protein serine/threonine kinase, histidine kinase, and sugar-binding activities, and is annotated as a coreceptor capable of homodimerization. The gene is associated with pattern-triggered immunity signaling, detection of bacteria, defense responses involving callose deposition, and regulation of defense against fungi and oomycetes. It is linked to pollen aperture formation, somatic embryogenesis, phloem transport, and cytokinin signaling. Associations with agronomic traits include fruit width, length, and shape, bacterial blight disease resistance, leaf rolling response, root hair length, and stomatal closure. The protein localizes to the plasma membrane, endosome, and extracellular region. Related genes in other species are linked to flagellin perception and antibacterial resistance.
