Analysis of the Heterogeneous Transcripts of the Highly Edited orf206 in Tomato Mitochondria

RNA editing of tomato orf206, postulated to encode a subunit of the ABC-type heme transporter involved in the biogenesis of cytochrome c, was analyzed by sequencing products of RT-PCR. While half of the transcripts were fully edited, others were heterogeneous as a result of partial or unusual editing.
