RLK — Pisum sativum

Summary

PsRLK (PSAT4G084280) on garden pea chromosome 4LG4 encodes a non-specific serine/threonine protein kinase with transmembrane receptor activity, belonging to the PRK1-6/SRF4-like family and containing leucine-rich repeats. It has histone H2AS1 kinase activity and receptor serine/threonine kinase binding functions. The gene is associated with regulation of floral meristem size, specification of floral organ number, stomatal complex morphogenesis, embryo sac and ovule development, immune response, heat acclimation, activation of salinity response, and cellular homeostasis. It localizes to the plasma membrane and extracellular region. Studies of related genes in other species link the family to seed weight, seed size, plant height, root length, chlorophyll content, photochemical quenching, stem elongation, proline content, and low nitrogen stress tolerance.
