COP1 (PSAT0S2625G0080) — Pisum sativum

Summary

PsCOP1, the garden pea gene on chromosome CAADHX020007870.1, encodes a protein with multiple molecular functions including pre-mRNA 5'-splice site binding, adenylyltransferase activity, phytochrome binding, and ubiquitin ligase substrate adaptor activity, and belongs to the POT family and MFS transporter superfamily. It is associated with regulation of signaling, phytochrome signaling, response to red or far red light, detection of light, leaf formation, brassinosteroid and cytokinin anabolism, and upregulation of photosynthesis. The gene is linked to numerous traits including grain yield, plant growth hormone response, light quality response, UV-A and far red light sensitivity, leaf area, flower diameter, root system morphology, and responses to spot blotch, downy mildew, copper, glyphosate, and nitrogen. Related genes in other species are associated with photomorphogenesis, shade avoidance, anthocyanin pigmentation, pathogen defense, and organ size regulation.
