Abstract
Unlike most bilateral animals, the blood-sucking lice of humans have extensively fragmented mitochondrial genomes. Human head louse and body louse have their 37 mitochondrial genes on 20 minichromosomes. In human pubic louse, the 34 known mitochondrial genes are on 14 minichromosomes. To understand the process of mt genome fragmentation in the blood-sucking lice of mammals, we sequenced the mt genomes of the domestic pig louse, Haematopinus suis, and the wild pig louse, Haematopinus apri, which diverged from human lice ~65 million years ago. The 37 mt genes of the pig lice are on nine circular minichromosomes; each minichromosome is 3-4 kb in size. The pig lice have four genes per minichromosome on average, in contrast to two genes per minichromosome in the human lice. One minichromosome of the pig lice has eight genes and is the most gene-rich minichromosome found in the sucking lice. Our results indicate substantial variation in the rate and extent of mt genome fragmentation among different lineages of the sucking lice.
