RLK — Lactuca sativa

Summary

LsRLK, encoded by the gene LSAT_V11C500286170 on lettuce chromosome 5, is a transmembrane receptor protein serine/threonine kinase with lectin domains, histidine kinase activity, and sugar-binding capacity. It is associated with pollen aperture formation, rejection of self-pollen, defense response to oomycetes, immune response, cellular response to ethylene, cytokinin signaling, detection of brassinosteroid stimulus, response to salicylate, and salinity response. The gene is linked to ethylene sensitivity, defense against herbivory, and methyl jasmonate-mediated stomatal closure. It localizes to the plasma membrane, endoplasmic reticulum, nucleus, cytosol, and extracellular region. Related genes in other species are linked to stomatal immunity, resistance to Pseudomonas syringae, Fusarium crown and root rot resistance, and traits including drought tolerance, salt response, fruit size, root length, and lycopene content.
