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.

Repeat regions of mitogenomes from some representative species of Hemiptera. (a) the repeat region of Triatoma dimidiata (Hemiptera: Heteroptera: Reduviidae); (b) the repeat region of Gorpis humeralis (Hemiptera: Heteroptera: Nabidae); (c) the repeat region of Schizaphis graminum (Hemiptera: Sternorrhyncha: Aphididae).

ijms-16-12382-f006: Repeat regions of mitogenomes from some representative species of Hemiptera. (a) the repeat region of Triatoma dimidiata (Hemiptera: Heteroptera: Reduviidae); (b) the repeat region of Gorpis humeralis (Hemiptera: Heteroptera: Nabidae); (c) the repeat region of Schizaphis graminum (Hemiptera: Sternorrhyncha: Aphididae).

Mentions: In general, the NC regions of an insect mitogenome consist of a control region and short intergenic spacers. However, some special species of Hemiptera include one repeat region (Figure 6). These repeat regions mainly are located into different positions (trnE-trnF, trnI-trnQ and trnS-nad1) in three families (Aphididae, Nabidae and Reduviidae), and differ in repeat unit sequence and copy number, suggesting that they are highly species-specific (Table 2). These repeat regions are not similar to any known sequences in GenBank. We speculate that this region, full of tandem repeats, has a function similar to the intergenic spacer in Apis mellifera that is thought to be another origin of replication [77].
