RLK — Oryza sativa Japonica

Summary

OsRLK (OS06G0638500) encodes a transmembrane receptor protein serine/threonine kinase with leucine-rich repeat domains, belonging to the PRK1-6/SRF4-like family. It exhibits histone H2AS1 kinase activity, coreceptor activity, steroid binding, SNARE binding, and signaling receptor activity. The gene is associated with strigolactone anabolism, gibberellin biosynthesis, root system development, pollen aperture formation, sexual reproduction, auxin transport, carbohydrate transport, and fatty acid and glutathione metabolism. It localizes to the membrane, plasmalemma, and endosome. OsRLK is associated with grain yield, plant height, stem elongation, drought tolerance and sensitivity, stomatal resistance, glume opening, and ABA response. Related genes in other species are linked to low nitrogen stress tolerance and immunity.
