RLK — Oryza sativa Japonica

Summary

OsRLK (OS09G0268100) on rice chromosome 9 encodes a protein with a legume lectin domain and a serine/threonine kinase domain, and is associated with histidine kinase activity, sugar binding, SNARE binding, steroid binding, signaling receptor activity, and other molecular functions. The gene is associated with strigolactone and gibberellin biosynthesis, auxin transport, carbohydrate transport, root system development, cell fate specification, pollen aperture formation, sexual reproduction, meiosis, fatty acid and glutathione metabolism, the TCA cycle, and histidyl-aspartyl phosphorelay signaling. It is linked to grain yield, plant height, stem elongation, glume opening, stomatal resistance, drought sensitivity and tolerance, and salt tolerance. The protein localizes to the membrane, plasmalemma, endosome, cytosol, pollen aperture, and macromolecular complexes. Studies of related genes in other species connect the lectin receptor kinase family to stress signaling and development.
