RLK — Oryza sativa Japonica

Summary

OsRLK (OS10G0442000) on rice chromosome 10 encodes a transmembrane receptor protein serine/threonine kinase with histidine kinase activity, sugar binding, and protein homodimerization activity, belonging to the L-type lectin receptor kinase family. The gene is associated with strigolactone and gibberellin biosynthesis, auxin transport, carbohydrate transport, root system development, cell fate specification, pollen aperture formation, sexual reproduction, and regulation of developmental growth. It localizes to the plasma membrane, cytosol, and pollen aperture. Associations with agronomic traits include grain yield, plant height, stem elongation, glume opening, stomatal resistance, and both drought sensitivity and drought tolerance. Related genes in other species such as CHARK, DAF1, SIT1, and SIT2 link the lectin receptor kinase family to stress signaling and developmental processes.
