COP1 (PSAT4G041800) — Pisum sativum

Summary

PsCOP1 (PSAT4G041800) on garden pea chromosome 4LG4 encodes a protein with multiple domains including PPR repeats, DYW and E+ motifs, and is annotated with pre-mRNA 5'-splice site binding, adenylyltransferase activity, and ubiquitin ligase substrate adaptor functions. This gene is associated with regulation of phytochrome signaling, light detection, leaf formation, photosynthesis upregulation, and brassinosteroid and cytokinin anabolism. It has been linked to traits including grain yield, leaf area, flower diameter, root morphology, chlorophyll ratio, and responses to UV-A, far-red light, copper, glyphosate, and nitrogen. Phenotype associations include seed longevity, salinity tolerance, early flowering, altered light response, reduced chlorophyll, and cell wall integrity. Related genes in other species are linked to photomorphogenesis, anthocyanin pigmentation, pathogen defense, and shade avoidance.
