PSAT4G123440 — Pisum sativum

Summary

PsCOP1 (PSAT4G123440) on garden pea chromosome 4LG4 encodes a protein with DYW, PPR and TPR-like helical domains, and is annotated with pre-mRNA 5'-splice site binding, adenylyltransferase activity, and ubiquitin ligase substrate adaptor functions. The gene is associated with regulation of phytochrome signaling, response to red or far-red light, detection of light, and upregulation of photosynthesis. It has been linked to traits including grain yield, leaf area, chlorophyll ratio, flower diameter, root system morphology, plant growth hormone response, and sensitivity to UV-A, far-red light, copper, glyphosate, and nitrogen. Associations also include seed longevity, salinity stress tolerance, seed development, cell wall integrity, and abscisic acid responsiveness. Related genes in other species are linked to photoperiod sensitivity, shade-induced hypocotyl elongation, anthocyanin pigmentation, and resistance to Botrytis cinerea and turnip crinkle virus.
