ER1 — Pisum sativum

Summary

PSAT0S1728G0200 (ER1) in garden pea (Pisum sativum) encodes a transmembrane receptor serine/threonine kinase with leucine-rich repeat domains, exhibiting ATP binding and protein serine kinase activity. The gene is associated with multiple developmental and stress-related processes, including sporulation, megasporogenesis, microsporogenesis, anther wall tapetum development, embryo sac development, plant ovule development, and stomatal complex morphogenesis. It is linked to the upregulation of defense response, activation of defense response to bacteria, salinity response, heat acclimation, and response to other organisms. The encoded protein localizes to the ER membrane, cortical ER, perinuclear ER membrane, plasmalemma, nucleus, and extracellular regions. Studies of related genes in other species connect the family to immune signaling and developmental regulation.
