Overview of OR functions. Targets and associated processes of ORANGE family proteins (representing by OR here) and ORANGEORANGE (OROR) isoforms are noted in the chromoplast, chloroplast, and nucleus, which are experimentally verified. Other OR functions with undefined mechanisms are listed. ARC3, accumulation and replication of chloroplasts 3; CHLI, magnesium chelatase subunit I; eRF1-2, eukaryotic release factor 1–2; FBN1, fibrillin 1; LHCB, light-harvesting chlorophyll a/b binding; PsbP, oxygen-evolving enhancer protein; PSY, phytoene synthase; TCP14, teosinte branched1/cycloidea/proliferating cell factor 14; TIC40/TIC110, translocon at the inner chloroplast envelope 40/110. ELIPs, Early Light-Inducible Proteins; eRF1, Eukaryotic Release Factor1
