Comparative mitogenomes of six species in the subfamily Iassinae (Hemiptera: Cicadellidae) and phylogenetic analysis

For elucidating phylogenetic relationships among members of the family Cicadellidae, mitogenomes of six members of the subfamily Iassinae, including Batracomorphus lateprocessus, Iassus dorsalis, Krisna concava, Krisna rufimarginata, Gessius rufidorsus, and Trocnadella arisana, were sequenced. The m...

Description
Summary:For elucidating phylogenetic relationships among members of the family Cicadellidae, mitogenomes of six members of the subfamily Iassinae, including Batracomorphus lateprocessus, Iassus dorsalis, Krisna concava, Krisna rufimarginata, Gessius rufidorsus, and Trocnadella arisana, were sequenced. The mitogenomes are 14,724–15,356-bp long. Moreover, typical 37 genes in mitogenomes were identified; arrangement of these genes in the studied species was consistent with that in the inferred ancestral insects, except for tRNA genes, with a simple switch between the positions of trnI and trnQ in Trocnadella arisana. Most protein-coding genes in the Iassinae mitogenomes showed typical ATN start codons (ATA/ATT/ATC/ATG) and TAR (TAA/TAG) or an incomplete stop codon T--; ATP8 of all sequenced species showed the start codon TTG. The secondary structures of 16S rRNA and 12S rRNA were predicted. 16S rRNA comprised 6 domains with 43 helices, and 12S rRNA comprised 3 domains with 25 helices. All subfamilies, except Cicadellinae and Evacanthinae, were recovered as monophyletic. As reported previously, treehoppers originated from paraphyletic Cicadellidae. Iassinae and Coelidiinae, Megophthalminae and treehoppers, and Cicadellinae and Evacanthinae were sister groups with high nodal support.
