RLK — Pisum sativum

Summary

PsRLK (PSAT3G136000) on garden pea chromosome 3LG5 encodes a transmembrane receptor serine/threonine kinase with a legume lectin domain, belonging to the L-type lectin receptor kinase family. It exhibits coreceptor activity, histidine kinase activity, sugar binding, and protein homodimerization activity. The gene is associated with pollen aperture formation and development, somatic embryogenesis, nodulation, cellular homeostasis, and regulation of growth. It is linked to defense responses against oomycetes and fungi, upregulation of innate immune response, inhibition of salinity response, and cytokinin signaling. Associations with salt tolerance and pathogen resistance have been noted. The protein localizes to the membrane, plasmalemma, endoplasmic reticulum, extracellular region, cytosol, and pollen aperture. Related genes in other species are linked to seed germination.
