COP1 (PSAT3G066800) — Pisum sativum

Summary

PsCOP1 (PSAT3G066800) on garden pea chromosome 3LG5 encodes a protein with multiple annotated molecular functions including monosaccharide transmembrane transporter activity, pre-mRNA 5'-splice site binding, ubiquitin ligase substrate adaptor activity, and phytochrome binding. The gene is associated with regulation of phytochrome signaling, response to red or far red light, detection of light, leaf formation, upregulation of photosynthesis, and cytokinin and brassinosteroid anabolism. It has been linked to traits including grain yield, leaf area, flower diameter, root system morphology, branch angle, plant growth hormone response, and sensitivities to UV-A light, copper, glyphosate, and far red light. Associations with seed longevity, salinity stress tolerance, seed development, pollen germination, cell wall integrity, and light-regulated gene expression have also been observed.
