ER1 — Pisum sativum

Summary

PSAT5G007040 (ER1) on chromosome 5LG3 of garden pea encodes a protein kinase domain-containing protein with leucine-rich repeat (LRR) and receptor-like kinase (RLK) domains. The gene is associated with multiple molecular functions including protein tyrosine kinase activity, steroid binding, SNARE binding, and signaling receptor activity. It has been linked to biological processes such as sporulation, megasporogenesis, microsporogenesis, stomatal complex morphogenesis, anther wall tapetum development, detection of brassinosteroid stimulus, and heat acclimation. Localization evidence connects the product to the plasma membrane, endosome, plant-type cell wall, and plasmodesmata. Studies of related genes in other species link the LRR-RLK family to stress responses and developmental regulation, though these associations are not yet established in pea.
