RLK — Oryza sativa Japonica

Summary

OsRLK (OS07G0575600) encodes a transmembrane receptor protein serine/threonine kinase with lectin domains, possessing histidine kinase activity, sugar binding, and signaling receptor activity. The gene is associated with strigolactone and gibberellin biosynthesis, auxin transport, root system development, cell fate specification, pollen aperture formation, and sexual reproduction. It has been linked to agronomically important traits including grain yield, plant height, stem elongation, glume opening, stomatal resistance, and both drought sensitivity and drought tolerance. The protein localizes to the plasma membrane, endosome, cytosol, and pollen aperture. Studies of related genes in other species connect the lectin-receptor kinase family to stress signaling and developmental regulation.
