ER1 — Pisum sativum

Summary

PSAT0S3011G0040 (symbol ER1, also known as PsLRR, DRT100, and EXLRR8) on garden pea chromosome CAADHX020008961.1 encodes a leucine-rich repeat (LRR) domain-containing protein with nucleotide, steroid, SNARE, and receptor serine/threonine kinase binding activities, as well as signaling receptor, protein serine kinase, and protein heterodimerization activities. The gene is associated with UV protection and response, sporulation, regulation of meristem development, skotomorphogenesis, detection of brassinosteroid stimulus, lateral root formation, nodulation, flower development, heat acclimation, and seedling development. It is linked to DNA damage repair and localizes to the membrane, endosome, apoplast, and macromolecular complexes. Studies of related genes in other species connect the family to traits including seed weight, seed size, drought tolerance, chlorophyll content, root length, and days to flowering.
