Abstract

In a study of transcribed regions of the wheat mitochondrial genome, we identified an open reading frame of 720 bp, which was consequently designated orf240. The amino acid sequence deduced from orf240 shows ahigh level of similarity with HelC, a protein essential for c-type cytochrome biogenesis in the photosynthetic purple bacterium Rhodobactercapsulatus. HelC is part of a purative heme ABC transporter. An open reading frame homologous to orf240 is present in the mitochondrial genome of Marchantia polymorpha. The wheat gene is expressed as an mRNA of 2.8 kb, which is further processed to smaller transcripts. The transcript is highly edited, with 36 C to U modifications found in the coding region of all cDNAs sequenced. RNA editing is responsible for changes in 14% of the amino acids specified by the transcript.
