The only copy of atp6 in cms-C, designated C-atp6, is a triple gene fusion product comprised of DNA sequences derived from atp9, atp6, and an unknown origin. Sequences of cDNAs revealed 19 C to U alterations resulting in 16 amino acid residue changes compared to the genomic sequence. The only C to U edit in the 39-nucleotide sequence similar to atp9 was comparable to a change in the complete atp9 mRNAs of Petunia, Oenothera, wheat, and sorghum. The 442 nucleotides of unknown origin were not edited. The 18 editing events within the atp6 homologous region were similar to those in the atp6 transcripts of sorghum. RNA editing in maize C-atp6 transcripts introduces a translational stop codon at the same position where it is created by editing in sorghum and Oenothera atp6 mRNAs and is already present in atp6 open reading frames of most other plant and non-plant organisms. Our results, along with other reports on editing in chimeric transcripts, indicate that RNA editing is not influenced by rearrangements but instead is sequence specific.}, number={2}, journal={CURRENT GENETICS}, author={KUMAR, R and LEVINGS, CS}, year={1993}, month={Feb}, pages={154–159} }
