RNA editing of ATPase subunit 9 transcripts in Oenothera mitochondria.
The mRNA for subunit 9 of the ATPase (atp9) in the higher plant Oenothera is edited in four nucleotide positions. Three events alter genomic serine and proline codons to triplets specifying leucine. A UGA termination codon is introduced into the reading frame by modification of a CGA arginine codon. This modification shortens the polypeptide by four amino acids. Direct sequencing of PCR amplified cDNA from the total mitochondrial mRNA population gives no indication of partially edited transcripts suggesting a rapid and efficient modification of atp9 transcripts in Oenothera mitochondria.
