The subgroup of PLS-type PPR proteins were found to be the main specificity factors of cytidine to uridine Introduction RNA editing. Identifying the targets of PLS-type PPR proteins can help in elucidating the molecular function of Mitochondria play an important role in a multitude of pro- proteins encoded in the organellar genomes.
