RLK — Oryza sativa Japonica

Summary

OsRLK (OS03G0258000) on rice chromosome 3 encodes a transmembrane receptor serine/threonine kinase with a legume lectin domain, possessing histidine kinase activity, sugar binding, and signaling receptor activity. This gene is associated with strigolactone and gibberellin biosynthesis, auxin transport, carbohydrate transport, root system development, cell fate specification, pollen aperture formation, and sexual reproduction. It is linked to traits including grain yield, plant height, stem elongation, glume opening, drought tolerance and sensitivity, stomatal resistance, and salt tolerance. The product localizes to the pollen aperture, plasma membrane, endoplasmic reticulum, vacuole, mitochondria, nucleus, and cytosol. Related genes in other species are linked to reactive oxygen species, ethylene production, and stomatal immunity.
