PSAT3G161240 — Pisum sativum

Summary

PSAT3G161240 (STC, also known as PsCOP1) on garden pea chromosome 3LG5 encodes a protein with multiple annotated molecular functions including pre-mRNA 5'-splice site binding, monosaccharide transmembrane transporter activity, phytochrome binding, and ubiquitin ligase substrate adaptor activity. The protein belongs to the major facilitator superfamily (MFS) of sugar transporters. This gene is associated with regulation of signaling, phytochrome signaling pathways, response to red or far red light, detection of light, leaf formation, and upregulation of photosynthesis. It is linked to numerous traits including grain yield, plant growth hormone response, light quality response, UV-A and far red light sensitivity, leaf area and angle, flower diameter and morphology, root system morphology, branch angle, vegetative vigor, and responses to various stresses including spot blotch, downy mildew, copper, glyphosate, nitrogen, and phosphorus. Related genes in other species are linked to photomorphogenesis, flowering time, anthocyanin pigmentation, and pathogen defense responses.
