RLK — Pisum sativum

Summary

PsRLK (PSAT3G136840) on garden pea chromosome 3LG5 encodes a transmembrane receptor protein serine/threonine kinase with lectin domains, belonging to the L-type lectin receptor kinase family. It possesses coreceptor activity, histidine kinase activity, sugar binding, and protein homodimerization activity. This gene is associated with pollen aperture formation and development, somatic embryogenesis, nodulation, defense response to oomycetes, regulation of defence response to fungi, upregulation of innate immune response, inhibition of salinity response, cytokinin signaling, response to salicylate, cellular homeostasis, and regulation of growth. It localizes to the pollen aperture, endoplasmic reticulum, extracellular region, cytosol, and plasmalemma. Overexpression studies link PsRLK to salt tolerance and pathogen resistance. Studies of related genes in other species connect the family to seed germination, seed weight, seed size, chlorophyll content, root hair length, proline content, and disease tolerance.
