The largest aphid mitochondrial genome found in invasive species Therioaphis tenera (Aizenberg, 1956)

Abstract

The complete mitochondrial genome of Therioaphis tenera (Aizenberg) was sequenced using Ion Torrent sequencing technology. The genome is 19,200 bp in length, which is the largest mitochondrial genome of aphids that has been sequenced so far. Therioaphis tenera mtDNA contains the D-loop, 36 coding genes instead of typical 37 due to the absence of Phe-tRNA, and a repeat region which is extremely long (3013 bp). Among all aphids with sequenced mitochondrial genomes, only T. tenera has a smaller number of genes in the mtDNA.
