PSBO — Pisum sativum

Summary

PSAT5G183920 (symbol PSBO) in garden pea (Pisum sativum) on chromosome 5LG3 encodes a PsbO family protein with oxygen-evolving activity and poly(U) binding. The gene is associated with photosystem II stabilization and assembly, photosynthesis light reactions, thylakoid membrane organization, nonphotochemical quenching, membrane organization, protein import, and de-etiolation. It is linked to photochemical quenching and localized to the chloroplast photosystem II, the OEC (PSII) complex, and the chloroplast thylakoid membrane. Related genes in other species connect the family to the OEE1 protein, but these associations are not established for this gene.
