Complete mitochondrial genome of Rhopalosiphum maidis (Hemiptera: Aphididae) and its phylogenetic implications.

Abstract

Rhopalosiphum maidis Fitch, 1856 is widespread in tropical and temperate regions. R. maidis can spread viral diseases in maize and harm various important crops. In the present study, we report the first complete mitochondrial genome of R. maidis. The circular genome is found to be 17,021 bp in length, includes a standard set of 22 transfer RNAs, two ribosomal RNAs, 13 protein-coding genes, and two non-coding control regions. The base composition is 84.32% AT and 15.79% GC. The phylogenetic tree of the 17 Aphidini families constructed based on the nucleotide sequences of complete mitochondrial genomes strongly supports the conclusion that R. maidis is closely related to R. rufiabdominalis.
