Mutation of the pentatricopeptide repeat-SMR protein SVR7 impairs accumulation and translation of chloroplast ATP synthase subunits in Arabidopsis thaliana.

Abstract excerpt

RNA processing, RNA editing, RNA splicing and translational activation of RNAs are essential post-transcriptional steps in chloroplast gene expression. Typically, the factors mediating those processes are nuclear encoded and post-translationally imported into the chloroplasts. In land plants, members of the large pentatricopeptide repeat (PPR) protein family are required for individual steps in chloroplast RNA...
