PSAT7G232000 — Pisum sativum

Summary

PsCOP1 (PSAT7G232000) on garden pea chromosome 7LG7 encodes a protein with pre-mRNA 5'-splice site binding, adenylyltransferase, amino acid binding, phytochrome binding, and ubiquitin ligase substrate adaptor activities, and belongs to the POT and MFS transporter superfamilies. It is associated with regulation of signaling, phytochrome and red/far-red light responses, leaf formation, photosynthesis upregulation, lateral root development, fermentation, gluconeogenesis, and cytokinin, brassinosteroid, and amino acid anabolism. The gene is linked to traits including grain yield, leaf area, flower diameter, inflorescence number, chlorophyll ratio, root morphology, branch angle, plant growth hormone response, and sensitivities to UV-A, copper, glyphosate, and far-red light. Phenotype associations include seed longevity, salinity tolerance, seed development, pollen germination, cell wall integrity, early flowering, and altered light response. Studies of related genes in other species link the family to photomorphogenesis, anthocyanin pigmentation, pathogen defense, and organ size regulation.
