Figure 1

A circular map of the complete mitochondrial genome of a bryozoan Bugula neritina (GenBank accession number AY690838). Protein and rRNA genes are abbreviated as follows: atp6 and atp8 (genes for ATPase subunits 6 and 8), cox1-cox3 (genes for cytochrome C oxidase subunits I-III), cob (gene for apocytochrome b), nad1-nad6 and nad4L (genes for NADH dehydrogenase subunits 1–6 and 4L), and rrnS and rrnL (genes for 12S and 16S rRNAs). All 22 tRNA genes are located among protein- and/or tRNA-coding genes. The tRNA genes are named using single-letter amino acid abbreviations, with the exception of those coding for leucine and serine, which are named L1 for the tRNALeu(CUN) (anticodon TAG) gene, L2 for the tRNALeu(UUR) (anticodon TAA) gene, S1 for the tRNASer(AGN) (anticodon GCT) gene and S2 for the tRNASer(UCN) (anticodon TGA) gene. The arrows indicate the orientations of the gene components. The three slashed regions corresponding to NC3, NC4 and NC10 may be related to the mode of regulation of mitochondrial replication and transcription.
