RLK — Lactuca sativa

Summary

LsRLK, encoded by the garden lettuce gene LSAT_V11C300134930 on chromosome 3, is a transmembrane receptor serine/threonine kinase with leucine-rich repeat domains, possessing coreceptor, signaling receptor, and protein kinase activities. It is associated with the upregulation of seed germination, abscisic acid-mediated signaling, and drought and salinity responses, as well as with floral organ development, stomatal complex morphogenesis, and gametophyte development. The gene is linked to drought tolerance, immune response, and ABA response. Studies of related genes in other species connect the family to traits including root volume, shoot dry weight, lycopene content, leaf curling, plant height, and abscisic acid sensitivity, as well as to low nitrogen stress tolerance.
