RLK — Oryza sativa Japonica

Summary

OsRLK (OS07G0130400) encodes a transmembrane receptor protein serine/threonine kinase with lectin domains, possessing histidine kinase activity, sugar binding, and protein homodimerization activity. In rice, this gene is associated with strigolactone and gibberellin biosynthesis, auxin transport, root system development, pollen aperture formation, sexual reproduction, and carbohydrate transport. It has been linked to grain yield, plant height, stem elongation, glume opening, drought tolerance and sensitivity, salt tolerance and sensitivity, stomatal resistance, and ethylene homeostasis. The protein localizes to the plasma membrane, endoplasmic reticulum, nucleus, mitochondria, and pollen aperture. Studies of related genes in other species link the family to reactive oxygen species production, stomatal immunity, and resistance to Pseudomonas syringae.
