COP1 (PSAT3G065880) — Pisum sativum

Summary

PsCOP1 (PSAT3G065880) on garden pea chromosome 3LG5 encodes a protein with domains characteristic of the MFS sugar transporter family, including the ERD6/Tret1-like and trehalose transporter subfamilies, and is annotated with monosaccharide transmembrane transporter activity, pre-mRNA 5'-splice site binding, and ubiquitin ligase substrate adaptor function. The gene is associated with regulation of phytochrome signaling, response to red or far-red light, light detection, leaf formation, upregulation of photosynthesis, and brassinosteroid and cytokinin biosynthesis. It has been linked to traits including grain yield, plant growth hormone response, UV-A and far-red light sensitivity, chlorophyll ratio, leaf area, flower diameter, root system morphology, and spot blotch response. Studies of related genes in other species connect the family to light-regulated gene expression, photoperiod sensitivity, and anthocyanin pigmentation.
