PSAT6G050680 — Pisum sativum

Summary

PsCOP1 (PSAT6G050680) on garden pea chromosome 6LG2 encodes a protein with MFS sugar transport-like and MFS domains, and is annotated with pre-mRNA 5'-splice site binding, adenylyltransferase activity, phytochrome binding, and ubiquitin ligase substrate adaptor activity. It is associated with regulation of phytochrome and red/far-red light signaling, detection of light, upregulation of photosynthesis and lateral root development, leaf formation, and responses to mycotoxin and magnetism. The gene is linked to traits including grain yield, leaf area, flower diameter, inflorescence number, chlorophyll ratio, root system morphology, branch angle, vegetative vigor, fruit set, and sensitivities to UV-A, far-red light, copper, glyphosate, and nitrogen. Phenotype associations include seed longevity, salinity tolerance, seed development, pollen germination, cell wall integrity, early flowering, altered light response, and chromatin organization. Studies of related genes in other species link the family to photomorphogenesis, anthocyanin pigmentation, and pathogen defense.
