| Popis: | A study of an invertebrate mitochondrial genome, that of the blowfly Phormia regina, has been initiated to compare its structural and functional relatedness to other metazoan mitochondrial genomes. A restriction map of mitochondrial DNA (mtDNA) isolated from sucrose gradient-purified mitochondria has been established using a combination of single and double restriction endonuclease digestions and hybridizations with isolated mtDNA fragments, revealing a genome size of 17.5 kilobases (kb). A number of mitochondrial genes including those encoding the 12 S and 16 S ribosomal RNA, the cytochrome c oxidase I subunit (COI) and an unidentified open reading frame (URF2) have been located on the Phormia mtDNA by Southern blot analysis using as probes both isolated mtDNA fragments and oligonucleotides derived from the sequences of previously characterized genes from rat and Drosophila yakuba mtDNAs. These data indicate that for those regions examined, the mitochondrial genome organization of blowfly mtDNA is the same as that of Drosophila yakuba, the order being COI-URF2-12 S-16 S. These data also report the presence of an A + T-rich region, located as a 2.5-kb region between the URF2 and the 12 S rRNA genes, and its amplification by the polymerase chain reaction is described. |
