Abstract

A highly transcribed region in Oenothera mitochondria codes for a reading frame (orf206) which shows high homology to the Marchantia encoded mitochondrial open reading frame orf277 and is also conserved in the mitochondrial genomes of Arabidopsis thaliana and Daucus carota. Transcripts of orf206 are modified by cytidine to uridine changes in 46 positions by RNA editing, affecting 30% of all cytidines and 15% of the total encoded amino acids. This ORF is cotranscribed with an upstream reading frame and with the downstream rps 14 gene. The orf206 deduced protein shows high similarity to polypeptides which are proposed to be part of an ABC-type heme transporter involved in cytochrome c biogenesis in Bradyrhizobium and Rhodobacter.
