RLK — Lactuca sativa

Summary

LsRLK, encoded by gene LSAT_V11C700375970 on lettuce chromosome 7, is a transmembrane receptor protein kinase with serine/threonine and tyrosine kinase activities, belonging to the PRK1-6/SRF4-like and LRR_N_plant-typ families. In lettuce, LsRLK is associated with upregulation of seed germination, regulation of floral meristem size and floral organ number, pollen maturation, megasporogenesis, microsporogenesis, anther wall tapetum development, stomatal complex morphogenesis, and plant ovule development. It is also linked to cellular response to drought, upregulation of abscisic acid mediated signaling, activation of salinity response, and drought tolerance. The protein localizes to the plasma membrane, cytoplasm, pollen tube, and extracellular regions. Related genes in other species are linked to traits such as root volume, shoot dry weight, plant height, fruit size, leaf number, and self-incompatibility.
