Hemipteran mitochondrial genomes: features, structures and implications for phylogeny.

Wang Y, Chen J, Jiang LY, Qiao GX - Int J Mol Sci (2015)

Bottom Line: Special attention is given to the comparative analysis of repeat regions.We also discuss and provide insights on the phylogenetic analyses of a variety of taxonomic levels.This review is expected to further expand our understanding of research in this field and serve as a valuable reference resource.

ABSTRACT
The study of Hemipteran mitochondrial genomes (mitogenomes) began with the Chagas disease vector, Triatoma dimidiata, in 2001. At present, 90 complete Hemipteran mitogenomes have been sequenced and annotated. This review examines the history of Hemipteran mitogenomes research and summarizes the main features of them including genome organization, nucleotide composition, protein-coding genes, tRNAs and rRNAs, and non-coding regions. Special attention is given to the comparative analysis of repeat regions. Gene rearrangements are an additional data type for a few families, and most mitogenomes are arranged in the same order to the proposed ancestral insect. We also discuss and provide insights on the phylogenetic analyses of a variety of taxonomic levels. This review is expected to further expand our understanding of research in this field and serve as a valuable reference resource.

Mentions: Triatoma dimidiata, the vector of Chagas disease, was the first published mitogenome of Hemipterain 2001 [9]. The sequencing history of hemipteran mitogenomes was shown (Figure 1a). There are two peaks during the past 14 years. Three years after the publication of the mitogenome of Triatoma dimidiata, Thao et al. [22] reported the complete nucleotide sequence of the mitogenomes of six species of whiteflies, one psyllid and one aphid from the suborder Sternorrhyncha. Four species of whiteflies had variations in gene order that were very different from the proposed insect ancestor (Drosophila yakuba) [16]. Subsequently, a number of studies have already proved that the rearrangements were more likely to happen in the mitogenomes of whiteflies than other insects of Hemiptera [22,23,24,25]. In 2008, Bu’s group obtained 10 complete and five nearly complete mitogenomes of Heteroptera [23] and they reported the first comparative mitogenome analysis of one suborder of Hemiptera and the phylogenetic relationships of Heteroptera [23]. With the development of PCR technology and the use of next-generation sequencing strategies [26,27,28], many complete mitogenome sequences of Hemiptera have been obtained and more will be sequenced (Figure 1a).
