Arabidopsis	At4g31850	Plays a role in the stabilization of the primary polycistronic transcript of the petL operon encoding subunits of the cytochrome b6-f complex.	PPR motifs of the nucleus-encoded factor, PGR3, function in the selective and distinct steps of chloroplast gene expression in Arabidopsis.; 2004; DOI: 10.1111/j.1365-313x.2004.02035.x; PMID: 15053768; https://pubmed.ncbi.nlm.nih.gov/15053768/
Arabidopsis	At1g74850	Involved in plastid gene expression.	pTAC2, -6, and -12 are components of the transcriptionally active plastid chromosome that are required for plastid gene expression.; 2006; DOI: 10.1105/tpc.105.036392; PMID: 16326926; https://pubmed.ncbi.nlm.nih.gov/16326926/
