  • Title: Complete mitochondrial genome of the aphid Hormaphis betulae (Mordvilko) (Hemiptera: Aphididae: Hormaphidinae).
    Author: Li YQ, Chen J, Qiao GX.
    Journal: Mitochondrial DNA A DNA Mapp Seq Anal; 2017 Mar; 28(2):265-266. PubMed ID: 26713493.
    Abstract:
    The complete mitochondrial genome of Hormaphis betulae has been sequenced and annotated, which is the first representation from the aphid subfamily Hormaphidinae. This mitogenome is 15 088 bp long with an A + T content of 82.2%, containing 37 genes arranged in the same order as the putative ancestral arrangement of insects and a control region. All protein-coding genes start with an ATN codon and terminate with a TAA codon or a single T residue. All the 22 tRNAs, ranging from 61 to 78 bp, have the typical clover-leaf structure except for trnS (AGN). The lengths of rrnL and rrnS genes are 1275 and 776 bp, respectively. The control region is 509 bp long and located between rrnS and trnI, including three domains: an AT-rich zone, a poly-thymidine stretch, and a stem-loop region. The phylogenetic tree supports H. betulae as the basal lineage within Aphididae.
