PSAT4G170600 — Pisum sativum

Summary

PsCOP1 (PSAT4G170600) on garden pea chromosome 4LG4 encodes a protein with a major facilitator superfamily (MFS) sugar transport-like domain and is annotated with diverse molecular functions including pre-mRNA 5'-splice site binding, adenylyltransferase activity, phytochrome binding, and ubiquitin ligase substrate adaptor activity. The gene is associated with regulation of signaling, phytochrome signaling, response to red or far red light, detection of light, upregulation of photosynthesis, leaf formation, and cytokinin and brassinosteroid anabolism. It has been linked to traits including grain yield, chlorophyll ratio, leaf area, flower diameter, root system morphology, plant growth hormone response, and sensitivity to UV-A, far red light, copper, glyphosate, and nitrogen. Phenotypic associations include seed longevity, salinity stress tolerance, seed development, cell wall integrity, early flowering, and altered light response. Studies of related genes in other species link the family to anthocyanin pigmentation and pathogen defense.
