RLK — Oryza sativa Japonica

Summary

OsRLK (OS07G0130800) encodes a transmembrane receptor serine/threonine kinase with a legume lectin domain, possessing histidine kinase activity, sugar binding, and protein homodimerization activity. This rice gene on chromosome 7 is associated with strigolactone and gibberellin biosynthesis, carbohydrate transport, auxin transport, root system development, cell fate specification, pollen aperture formation, sexual reproduction, and regulation of developmental growth. It localizes to the plasmalemma, cytosol, and pollen aperture. The gene has been connected to grain yield, plant height, stem elongation, glume opening, stomatal resistance, and both drought sensitivity and drought tolerance, as well as salt tolerance. Studies of related genes in other species link the lectin receptor kinase family to signaling.
