PSAT2G047440 — Pisum sativum

Summary

PSAT2G047440 (COP1) on garden pea chromosome 2LG1 encodes a protein with multiple annotated molecular functions including monosaccharide transmembrane transporter activity, pre-mRNA 5'-splice site binding, phytochrome binding, and ubiquitin ligase substrate adaptor activity, and belongs to the MFS_ERD6/Tret1-like and MFS_trehalose transporter families. The gene is associated with regulation of phytochrome signaling, detection of light, response to red or far red light, upregulation of photosynthesis, leaf formation, and fermentation. It has been linked to traits including grain yield, leaf area, flower diameter, root system morphology, light quality response, chlorophyll ratio, plant growth hormone response, and sensitivity to UV-A, far red light, copper, glyphosate, and nitrogen. Associations also include seed longevity, salinity stress tolerance, seed development, pollen germination, cell wall integrity, and abscisic acid responsiveness. Related genes in other species are linked to photoperiod sensitivity, pathogen defense, and shade-induced hypocotyl elongation.
