RLK — Oryza sativa Japonica

Summary

OS04G0531400 (RLK, also known as SIT2) encodes a transmembrane receptor serine/threonine kinase with a legume lectin domain, exhibiting histidine kinase activity, coreceptor activity, sugar binding, and protein homodimerization activity. This rice gene on chromosome 4 is associated with strigolactone and gibberellin biosynthesis, auxin transport, signaling, root system development, pollen aperture formation, and sexual reproduction. It has been linked to grain yield, drought tolerance, salt tolerance, plant height, stem elongation, glume opening, stomatal resistance, and hypersensitivity. The protein localizes to the plasmalemma, extracellular region, ER, mitochondria, nucleus, cytosol, and plant-type vacuole. Related genes in other species are associated with stomatal immunity, reactive oxygen species production, ethylene production, and resistance to Pseudomonas syringae.
