RLK — Oryza sativa Japonica

Summary

OsRLK (OS07G0575750) on rice chromosome 7 encodes a transmembrane receptor protein serine/threonine kinase with histidine kinase activity, coreceptor activity, and sugar binding, belonging to the L-type lectin receptor kinase family. It is associated with signaling, strigolactone and gibberellin biosynthesis, auxin transport, carbohydrate transport, root system development, cell fate specification, pollen aperture formation, sexual reproduction, meiosis, fatty acid and glutathione metabolism, the TCA cycle, and histidyl-aspartyl phosphorelay. The protein localizes to the plasma membrane, cytosol, and pollen aperture. Associations with agronomic traits include grain yield, plant height, stem elongation, glume opening, stomatal resistance, drought sensitivity and tolerance, and salt tolerance. Related genes in other species, such as CHARK and SERL2, link the family to additional signaling roles.
