PSAT6G207680 — Pisum sativum

Summary

PsCOP1 (PSAT6G207680) on garden pea chromosome 6LG2 encodes a protein with DYW, PPR, and TPR-like domains, annotated with pre-mRNA 5'-splice site binding, adenylyltransferase activity, and ubiquitin ligase substrate adaptor function. It is associated with regulation of phytochrome signaling, response to red or far-red light, detection of light, upregulation of photosynthesis, leaf formation, brassinosteroid and cytokinin anabolism, and fermentation. The gene is linked to traits including grain yield, plant growth hormone response, light quality response, chlorophyll ratio, leaf area, flower diameter, root system morphology, and spot blotch response. Phenotypic associations include seed longevity, salinity stress tolerance, seed development, cell wall integrity, and altered light response with shorter hypocotyl and late flowering. Related genes in other species are linked to photoperiod sensitivity, shade-induced hypocotyl elongation, pathogen defense, and anthocyanin pigmentation.
