Abstract

The complete mitochondrial genome of the Aster leafhopper Macrosteles quadrilineatus was sequenced using an Illumina-based next-generation sequencing approach. The genome is 16,626 bp in length with 78.0% AT content. It encodes 37 typical mitochondrial genes including 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 1 A + T-rich region. Two tandem repeats were identified within the A + T-rich region. One tRNA gene rearrangement (trnW-trnC-trnY→trnC-trnW-trnY) was found between nd2 and cox1.

Highlights

  • The leafhopper family Cicadellidae (Hemiptera) is distributed worldwide with over 2600 genera and about 21,000 species (Camisao et al 2014)

  • The subfamily, Deltocephalinae, contains some of the most economically important leafhopper species, accounting for a disproportionate 77% of all agricultural pest species in the Cicadellidae (Zahniser & Dietrich 2008). One such species is the aster leafhopper, Macrosteles quadrilineatus, that is widespread throughout the North American continent

  • Macrosteles quadrilineatus relies on bacterial symbionts for the provisioning of essential amino acids that are limited in their phloem diets, which helped the host exploit novel niches (Moran 2007)

Introduction

The leafhopper family Cicadellidae (Hemiptera) is distributed worldwide with over 2600 genera and about 21,000 species (Camisao et al 2014). It encodes 37 typical mitochondrial genes including 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 1 A þ T-rich region. Two tandem repeats were identified within the A þ T-rich region. One tRNA gene rearrangement (trnW-trnC-trnY!trnC-trnW-trnY) was found between nd2 and cox1.
