RLK — Oryza sativa Japonica

Summary

OsRLK (OS12G0574700) on rice chromosome 12 encodes a transmembrane receptor protein serine/threonine kinase with lectin domains, exhibiting histidine kinase activity, sugar binding, and ATP binding. It is associated with signaling, strigolactone and gibberellin biosynthesis, auxin transport, root system development, carbohydrate transport, fatty acid and glutathione metabolism, the TCA cycle, meiosis, sexual reproduction, cell fate specification, pollen aperture formation, and developmental growth regulation. The protein localizes to the membrane, plasmalemma, cytosol, and pollen aperture. The gene is linked to grain yield, plant height, stem elongation, glume opening, stomatal resistance, drought sensitivity, drought tolerance, and salt tolerance. Studies of related genes in other species connect the lectin-receptor kinase family to stress signaling and development.
