Figure 1

Gene map of Oedogonium cpDNA. Thick lines on the inner circle represent the two copies of the IR (IRA and IRB), with the arrows indicating the transcription direction of the IR-encoded rRNA operon. Genes (filled boxes) on the outside of the outer circle are transcribed in a clockwise direction. Introns are represented by open boxes and intron ORFs are denoted by narrow, filled boxes. The rpoB gene consists of two separate ORFs (rpoBa and rpoBb) that are not associated with sequences typical of group I or group II introns. tRNA genes are indicated by the one-letter amino acid code followed by the anticodon in parentheses (Me, elongator methionine; Mf, initiator methionine). Only one of the two isomeric forms of the genome is shown here; these isomers differ with respect to the relative orientation of the SC regions.
