ER1 — Pisum sativum

Summary

PSAT6G022040 (symbol ER1) on garden pea chromosome 6LG2 encodes a transmembrane receptor protein serine/threonine kinase with ATP binding activity, belonging to the leucine-rich repeat receptor-like kinase (LRR-RLK) family. The gene is associated with reproductive shoot system development, floral organ development and specification of floral organ number, regulation of meristem organisation and cell growth, sporulation, gametophyte and embryo sac development, plant ovule development, phyllome development, stomatal complex morphogenesis and its regulation, heat acclimation, post-embryonic development, and responses to thirst and salinity. The encoded protein localises to the membrane, plasmalemma and extracellular region. Studies of related genes in other species link the family to meristem and organ size regulation.
