ER2 — Pisum sativum

Summary

PSAT5G204800 (symbol ER2, also known as PsLRR) on garden pea chromosome 5LG3 encodes a leucine-rich repeat (LRR) domain-containing protein with enzyme inhibitor activity, nucleotide binding, receptor serine/threonine kinase binding, and protein serine kinase activity. It is associated with UV protection and response, regulation of floral meristem size and organ development, upregulation of defense response, nodulation, lateral root formation, heat acclimation, gametophyte development, regulation of cell growth, and signal transduction. The protein localizes to the ER membrane, perinuclear ER, cortical ER, apoplast, plasmalemma, and nucleus. It is linked to DNA damage repair. Related genes in other species link the family to traits including seed weight, seed size, drought tolerance, chlorophyll content, root length, stomatal resistance, photochemical quenching, pollen fertility, and days to flowering.
