Comparative analysis of mitogenomes among six species of grasshoppers (Orthoptera: Acridoidea: Catantopidae) and their phylogenetic implications in wing-type evolution

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

“…The A+T content ranged from 72.3% ( F. nigritibia ) to 72.9% ( F. sunanensis ). A+T % was the highest in the A+T-rich region (83.4%) and the lowest in tRNA genes (69.6%), which is consistent with the characteristic of base composition bias in insect mitogenomes [ 4 , 22 , 23 , 40 ]. Strand bias was demonstrated in nucleotide compositional skew.…”

“…The complete mitogenomes of Filchnerella sunanensis Liu, 1982; Filchnerella amplivertica Li, Zhang & Yin, 2009; Filchnerella nigritibia Zheng, 1992; Filchnerella pamphag oides Karny, 1908; and Filchnerella dingxiensis Zhang, Xiao & Zhi, 2011, were sequenced, and their length was 15,656 bp, 15,657 bp, 15,661 bp, 15,661 bp and 15,666 bp, respectively ( Table 2 ). Their structures are the same as those of insects [ 4 , 40 ]. Each mitogenome was found to be composed of circular double-stranded molecules, containing the typical set of 37 genes (13 typical protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs)) and an A+T rich region ( Figure 1 ).…”

“…The long wing is an ancestral characteristic, the shortened wing is an evolutionary characteristic and the wing-lessness is the newest characteristic, which is based on the overall evolutionary trend of Acridoidea [ 3 ]. Chen et al [ 4 ] studied the phylogenetic implications in wing type evolution of Catantopidae. Does wing type evolution of species within one genus follow the above pattern?…”

“…With the development of PCR technology and DNA sequencing technology, the usage of DNA sequences to study the phylogeny and evolution of insects has become a popular method [ 4 , 11 , 12 , 13 , 14 , 15 ]. There are also a few reports on the related studies of Pamphagidae.…”

The (non) accuracy of mitochondrial genomes for family level phylogenetics: the case of erebid moths (Lepidoptera; Erebidae)

“…Nevertheless, many studies have applied mitochondrial genomes as a source of information to resolve phylogenetic relationships of varied evolutionary depth. Some studies focused on the relationships within a superorder (Cameron et al 2009;Talavera and Vila 2011;Li et al 2015), an order (Cameron et al 2007;Fenn et al 2008;Dowton et al 2009;Kim et al 2011;Timmermans et al 2014;López-López and Vogler 2017;Yang et al 2019), a family (Chen et al 2014(Chen et al , 2020bYang et al 2015;Li et al 2018Li et al , 2020Xu et al 2020;Zhang et al 2020) or shallower relationships like species level or even at population level.…”
