RLK — Oryza sativa Japonica

Summary

Os04G0531500 (RLK, also known as OsRLK) on rice chromosome 4 encodes a protein with a legume lectin domain and a serine/threonine kinase domain, and is annotated with histidine kinase activity, sugar binding, protein homodimerization activity, and transmembrane receptor protein serine/threonine kinase activity. This gene is associated with strigolactone and gibberellin biosynthesis, auxin transport, carbohydrate transport, root system development, cell fate specification, pollen aperture formation, sexual reproduction, and regulation of developmental growth. It is linked to traits including grain yield, plant height, stem elongation, glume opening, drought tolerance and sensitivity, stomatal resistance, and salt tolerance. The protein localizes to the plasmalemma, pollen aperture, plant-type vacuole, endoplasmic reticulum, mitochondria, cytosol, and nucleus. Related genes in other species connect the family to salt stress responses, ethylene homeostasis, root epidermal cell development, and methyl jasmonate-mediated stomatal closure.
