Arabidopsis	At1g10522	Involved in redox-mediated retrograde signaling to synchronize the expression of photosynthetic genes from both the nuclear and plastidic genomes, especially in excess light conditions.	The plastid redox insensitive 2 mutant of Arabidopsis is impaired in PEP activity and high light-dependent plastid redox signalling to the nucleus.; 2012; DOI: 10.1111/j.1365-313x.2011.04865.x; PMID: 22211401; https://pubmed.ncbi.nlm.nih.gov/22211401/ | Plastid encoded RNA polymerase activity and expression of photosynthesis genes required for embryo and seed development in Arabidopsis.; 2014; DOI: 10.3389/fpls.2014.00385; PMID: 25161659; https://pubmed.ncbi.nlm.nih.gov/25161659/
