RLK — Oryza sativa Japonica

Summary

OsRLK (OS07G0283050) on rice chromosome 7 encodes a transmembrane receptor protein serine/threonine kinase with a legume lectin domain, possessing histidine kinase activity, coreceptor activity, sugar binding, signaling receptor activity, and protein homodimerization activity. This gene is associated with strigolactone and gibberellin biosynthesis, fatty acid and glutathione metabolism, the TCA cycle, auxin and carbohydrate transport, root system development, cell fate specification, pollen aperture formation, meiosis, sexual reproduction, and regulation of developmental growth. It localizes to the pollen aperture, cytosol, and plasmalemma. Associations with agronomic traits include grain yield, plant height, stem elongation, glume opening, stomatal resistance, drought tolerance, drought sensitivity, and salt tolerance. Studies of related genes in other species link the family to similar signaling and stress-response processes.
