RLK — Phaseolus vulgaris

Summary

PHAVU_008G117800 (PvRLK) encodes a transmembrane receptor serine/threonine kinase with a legume lectin domain, classified as an L-type lectin receptor kinase. It exhibits histidine kinase activity, sugar binding, and protein kinase activity, and is localized to the plasma membrane, endoplasmic reticulum, cytosol, and pollen aperture. The gene is associated with diverse biological processes including nitrogen fixation, nodulation, defense response to oomycetes, immune response, cytokinin and brassinosteroid signaling, pollen aperture formation, programmed cell death, and inhibition of salinity response. It has been linked to salt tolerance and pathogen resistance in overexpression studies, and to root hair length. Related genes in other species are associated with seed germination, seed weight, seed size, chlorophyll content, proline content, photochemical quenching, and salt tolerance.
