RLK — Lactuca sativa

Summary

LsRLK, encoded by the garden lettuce gene LSAT_V11C400220180 on chromosome 4, is a receptor-like kinase (RLK) with leucine-rich repeat (LRR) and protein kinase domains. It exhibits protein serine/threonine kinase activity, ATP binding, and signaling receptor activity, and is associated with steroid binding, SNARE binding, and protein heterodimerization. The gene is associated with cellular response to drought, upregulation of seed germination and abscisic acid-mediated signaling, detection of brassinosteroid stimulus, heat acclimation, regulation of floral meristem size, and specification of floral organ number. It localizes to the plasma membrane, endosome, and extracellular regions. LsRLK is associated with drought tolerance, immune response, and ABA response. Related genes in other species link the gene family to traits including root volume, shoot dry weight, lycopene content, leaf curling, plant height, and abscisic acid sensitivity.
