RLK — Oryza sativa Japonica

Summary

OsRLK (OS10G0441900) on rice chromosome 10 encodes a transmembrane receptor serine/threonine kinase with lectin domains, exhibiting histidine kinase activity, sugar binding, and ATP binding. This gene is associated with signaling, strigolactone anabolism, gibberellin biosynthesis, auxin transport, carbohydrate transport, root system development, cell fate specification, pollen aperture formation, meiosis, sexual reproduction, fatty acid metabolism, glutathione metabolism, and the TCA cycle. The protein localizes to the membrane, plasmalemma, cytosol, and pollen aperture. OsRLK is linked to grain yield, plant height, stem elongation, glume opening, stomatal resistance, drought sensitivity, drought tolerance, and salt tolerance. Related genes in other species connect the family to root development and stress signaling.
