RLK — Pisum sativum

Summary

PsRLK (PSAT3G137000) on garden pea chromosome 3LG5 encodes a transmembrane receptor protein serine/threonine kinase with coreceptor activity, histidine kinase activity, and sugar binding, belonging to the L-type lectin receptor kinase family. It is associated with pollen aperture formation and development, somatic embryogenesis, nodulation, cellular homeostasis, and regulation of growth. The gene is linked to defense responses against oomycetes and fungi, immune response, upregulation of innate immune response, and inhibition of salinity response, as well as cytokinin signaling and response to salicylate. Localized to the membrane, plasmalemma, ER, cytosol, extracellular region, and pollen aperture, PsRLK is associated with salt tolerance and pathogen resistance. Related genes in other species are linked to seed germination.
