RLK — Glycine max

Summary

GmRLK (GLYMA_18G185400V4) on soybean chromosome 18 encodes a transmembrane receptor protein serine/threonine kinase with coreceptor activity, histidine kinase activity, sugar binding, and protein homodimerization activity, belonging to the L-type lectin receptor kinase family. It is associated with diverse biological processes including nitrogen fixation, seed development, leaf senescence, chlorophyll breakdown and anabolism, pollen aperture formation, defense response to oomycetes, immune response, cell death, cytokinin signaling, and inhibition of salinity response. The gene is linked to agronomically important traits such as seed weight, seed size, chlorophyll content, and salt tolerance, with overexpression studies connecting it to salt tolerance and pathogen resistance. It localizes to the plasmalemma, extracellular region, ER, cytosol, and pollen aperture. Related genes in other species are linked to seed germination.
