RLK — Oryza sativa Japonica

Summary

OsRLK (OS10G0533800) on rice chromosome 10 encodes a transmembrane receptor serine/threonine kinase with a legume lectin domain, exhibiting histidine kinase activity, sugar binding, and protein homodimerization activity. It is associated with signaling, strigolactone anabolism, gibberellin biosynthesis, root system development, auxin transport, carbohydrate transport, cell fate specification, pollen aperture formation, sexual reproduction, and meiosis. The gene is linked to grain yield, plant height, stem elongation, glume opening, stomatal resistance, drought tolerance, drought sensitivity, and salt tolerance. It localizes to the plasmalemma, cytosol, and pollen aperture. Related genes in other species link the lectin receptor kinase family to stress signaling and development.
