RLK — Lactuca sativa

Summary

LsRLK, encoded by the garden lettuce gene LSAT_V11C800395020 on chromosome 8, is a transmembrane receptor protein serine/threonine kinase with a legume lectin domain, coreceptor activity, histidine kinase activity, and sugar binding. It is associated with defense responses to bacteria, fungi, oomycetes, and herbivory, as well as with pollen aperture formation and development, ethylene sensitivity, cytokinin and brassinosteroid signaling, and cellular responses to salinity and salicylate. The protein localizes to the plasma membrane, endoplasmic reticulum, cytosol, nucleus, and pollen aperture. Studies of related genes in other species link the family to drought tolerance, salt response, fruit size, root volume, shoot dry weight, lycopene content, self-incompatibility, and resistance to Fusarium crown and root rot and Pseudomonas syringae.
