Processing and editing of S.tuberosum rps10 transcripts in cognate mitochondria. (A) Agarose gel electrophoresis of RT–PCR products of electroporated potato mitochondria. The sizes of precursor and spliced products are indicated. (B) Sequence analysis of the regions containing the C1, C2, C4 and C5 editing sites in mature transcripts. Site C3, present in the intron, is lost after splicing. Arrowheads indicate the target residue. In sequences, N indicates a mixture of C and U residues corresponding to unedited and edited transcripts, respectively.
