RLK — Oryza sativa Japonica

Summary

OsRLK (OS07G0130200) on rice chromosome 7 encodes a transmembrane receptor protein serine/threonine kinase with a legume lectin domain, possessing histidine kinase activity, sugar binding, and protein homodimerization activity. It is associated with strigolactone and gibberellin biosynthesis, auxin transport, root system development, cell fate specification, pollen aperture formation, sexual reproduction, and regulation of developmental growth. The gene is linked to grain yield, plant height, stem elongation, glume opening, drought tolerance and sensitivity, salt tolerance and sensitivity, stomatal resistance, and ethylene homeostasis. It localizes to the plasmalemma, pollen aperture, endoplasmic reticulum, plant-type vacuole, mitochondria, cytosol, nucleus, and extracellular region. Studies of related genes in other species link the family to stomatal immunity, reactive oxygen species production, ethylene production, and resistance to Pseudomonas syringae.
