RLK — Capsicum annuum

Summary

CaRLK (T459_23037) on pepper chromosome 9 encodes a transmembrane receptor serine/threonine kinase with histidine kinase activity, sugar binding, and ATP binding, belonging to the L-type lectin receptor kinase family. The gene is associated with diverse biological processes including pollen aperture formation, rejection of self-pollen, defense response against oomycetes, regulation of defense response to fungi, upregulation of innate immune response, cellular response to ethylene, cytokinin signaling, response to salicylate, somatic embryogenesis, seed germination, and regulation of developmental growth. It is also linked to ethylene sensitivity, defense against herbivory, and methyl jasmonate-mediated stomatal closure. The protein localizes to the plasma membrane, membrane, extracellular region, ER, cytosol, nucleus, and pollen aperture. Studies of related genes in other species connect the family to traits such as drought tolerance, salt response, fruit size, root volume, and resistance to Fusarium crown rot and Pseudomonas syringae.
