Comparative Analysis of Mitogenomes among Five Species of Filchnerella (Orthoptera: Acridoidea: Pamphagidae) and Their Phylogenetic and Taxonomic Implications

Abstract

Mitogenomes have been widely used for exploring phylogenetic analysis and taxonomic diagnosis. In this study, the complete mitogenomes of five species of Filchnerella were sequenced, annotated and analyzed. Then, combined with other seven mitogenomes of Filchnerella and four of Pamphagidae, the phylogenetic relationships were reconstructed by maximum likelihood (ML) and Bayesian (BI) methods based on PCGs+rRNAs. The sizes of the five complete mitogenomes are Filchnerella sunanensis 15,656 bp, Filchnerella amplivertica 15,657 bp, Filchnerella nigritibia 15,661 bp, Filchnerella pamphagoides 15,661 bp and Filchnerella dingxiensis 15,666 bp. The nucleotide composition of mitogenomes is biased toward A+T. All tRNAs could be folded into the typical clover-leaf structure, except that tRNA Ser (AGN) lacked a dihydrouridine (DHU) arm. The phylogenetic relationships of Filchnerella species based on mitogenome data revealed a general pattern of wing evolution from long wing to increasingly shortened wing.

Phylogenetic Implication of Large Intergenic Spacers: Insights from a Mitogenomic Comparison of Prosopocoilus Stag Beetles (Coleoptera: Lucanidae)

“…The slowest and fastest evolution rates were observed for cox1 and atp8 genes, respectively (Figure 3). Furthermore, the cox1 had the smallest evolutionary rate, indicating that positive selection was less powerful for this gene than functional constraints, as found in other insects or stag beetles [8,61,62].…”

Comparative analysis of mitogenomes among three species of grasshoppers (Orthoptera: Acridoidea: Gomphocerinae) and their phylogenetic implications

“…The control regions (A+T-rich region) of the mitochondrial genomes were all located between tRNA-Ile and rrnS, with sizes of 729 bp ( Dasyhippus peipingensis ), 728 bp ( Myrmeleotettix palpalis ), and 735 bp ( Aeropedellus prominemarginis ), and the A+T content was >83%, which were also referred to as AT-rich regions. The structures and nucleotide compositions of the three species are generally consistent with the mitochondrial genome structure of the Acrididae ( Zhang et al, 2023 ; Zheng et al, 2021 ), indicating that these mitochondrial genome’s structure is highly conserved ( Wei et al, 2010 ).…”

Comparative mitogenomic analysis provides evolutionary insights into Formica (Hymenoptera: Formicidae)

“…The use of mitogenomic data is a common approach to exploring phylogenetic relationships among different insect groups [ 68 , 69 ]. The sister relationship between Formica and Polyergus ants confirmed in the present work was largely congruent with the results of previous studies [ 6 ].…”
