Structure and Conservation of Tandem Repeats in the Mitochondrial DNA Control Region of the Least Brook Lamprey (Lampetra aepyptera)

The sequence and structure of the complete mtDNA control region (CR) ofM. cephalusfrom African, Pacific, and Atlantic populations are presented in this study to assess its usefulness in phylogeographic studies of this species. The mtDNA CR sequence variations amongM. cephaluspopulations largely exceeded intraspecific polymorphisms that are generally observed in other vertebrates. The length of CR sequence varied amongM. cephaluspopulations due to the presence of indels and variable number of tandem repeats at the3′hypervariable domain. The high evolutionary rate of the CR in this species probably originated from these mutations. However, no excessive homoplasic mutations were noticed. Finally, the star shaped tree inferred from the CR polymorphism stresses a rapid radiation worldwide, in this species. The CR still appears as a good marker for phylogeographic investigations and additional worldwide samples are warranted to further investigate the genetic structure and evolution inM. cephalus.

Mitochondrial Dna Control Region

The organization of the mitochondrial DNA (mtDNA) control region (CR) of the autumnal moth, Epirrita autumnata, is described. The E. autumnata CR presents a distinct type of lepidopteran CR with domains of non-repetitive and repetitive sequences. The CRs show considerable length variation owing to a variable number of short ~29-bp sequence blocks that are repeated between 6 and 14 times in tandem. The organization of such a tandem array is unique among the insect CRs examined so far. Furthermore, the E. autumnata CR, which may reach 1075 bp in length, is considerably longer than previously reported lepidopteran CRs, which reach 311499 bp in length. Like other lepidopteran CRs, the E. autumnata CR contains two long homopolymer runs that may be involved in mtDNA replication and (or) transcription.Key words: Lepidoptera, Epirrita autumnata, mitochondrial DNA, control region, tandem array.
