ER1 — Pisum sativum

Summary

PSAT7G127160 (symbol ER1) on garden pea chromosome 7LG7 encodes a transmembrane receptor protein serine/threonine kinase with protein serine kinase activity and ATP binding, belonging to the LRR-extensin-like regulator family. The gene is associated with floral organ development, specification of floral organ number, regulation of floral meristem size, and regulation of meristem organisation. It is linked to sporulation, gametophyte development, megasporogenesis, microsporogenesis, anther wall tapetum development, plant ovule development, and embryo sac development. Additional associations include stomatal complex morphogenesis and regulation of stomatal complex development, regulation of cell growth, heat acclimation, activation of salinity response, and upregulation of response to thirst. The encoded protein localises to the ER membrane, cortical ER, perinuclear ER membrane, plasmalemma, nucleus, and extracellular region. Studies of related genes in other species link the family to non-specific serine/threonine kinase activity (EC 2.7.11.1).
