Complete mitochondrial genomes of four species of praying mantises (Dictyoptera, Mantidae) with ribosomal second structure, evolutionary and phylogenetic analyses

Abstract

Praying mantises are distributed all over the world. Though some Mantodea mitogenomes have been reported, an evolutionary genomic and phylogenetic analysis study lacks the latest taxonomic system. In the present study, four new mitogenomes were sequenced and annotated. Deroplatys truncate, D. lobate, Amorphoscelis chinensis and Macromantis sp. belong to Deroplatyidae, Amorphoscelidae and Photinaidae family, respectively. Our results indicated that the ATP8 gene may be lost in D. truncate and D. lobata mt genome, and four tRNA genes have not been found in D. truncate, D. lobata and Macromantis sp. A dN/dS pair analysis was conducted and it was found that all genes have evolved under purifying selection. Furthermore, we tested the phylogenetic relationships between the eight families of the Mantodea, including 35 species of praying Mantis. Based on the complete mitochondrial genome data, it was also suggested as sister to Deroplatyidae + Mantidae, Metallyticus sp., the only representative of Metallyticidae, is sister to the remaining mantises. Our results support the taxonomic system of Schwarz and Roy and are consistent with previous studies.

Complete mitochondrial genome of Episymploce splendens (Blattodea: Ectobiidae): A large intergenic spacer and lacking of two tRNA genes

“…However, some exceptions, such as gene duplications, deletions or rearrangements, were found in some species [ 54 – 56 ]. Although tRNA deletion is unusual, increasing cases have been reported, such as three amphibians species [ 54 , 57 ], three reptile species [ 58 , 59 ], one crustacean species [ 60 ], one Hemiptera insect and one Coleoptera insect [ 61 ], four Psocoptera insects [ 10 , 62 ] and three Mantode a insects [ 9 ]. In this study, two tRNAs, tRNA-Gln and tRNA-Met, were absent in E .…”

“…So far, mitochondrial gene rearrangement has been reported in about 17 orders of insects, and these genes include protein coding gene, rRNA gene and tRNA gene [ 8 ]. In addition tRNAs, the missing protein coding genes have also been reported in Mantodea, Phthiraptera, and Psocoptera [ 9 – 13 ]. The changes of tRNAs are most various in no-typical insect mito-genomes, including tRNA translocation, tRNA loss, tRNA tandem duplication and tRNA conversion [ 4 , 9 – 10 , 14 , 15 ].…”

Phthiraptera and Psocoptera insect mito-genomes may be most multipartite and most fast in evolution, that they could fission into fragmented mito-genomes and have numerous pseudo-genes and diverse gene rearrangements [ 7 – 10 ].…”

Novel Mitochondrial Gene Rearrangement and Intergenic Regions Exist in the Mitochondrial Genomes from Four Newly Established Families of Praying Mantises (Insecta: Mantodea)

“…These species are distributed worldwide, mainly in tropical and subtropical areas, and occupy diverse habitats ranging from tropical rainforests to arid deserts [ 2 , 3 ]. There have been numerous studies exploring the taxonomic status within Mantodea based on morphology or molecular data [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ]. Existing research confirmed the monophyly of the order Mantodea and Mantodea clustered into Dictyoptera with Blattodea [ 4 , 17 , 20 ].…”

Mitochondrial Phylogenomics Suggests Complex Evolutionary Pattern of Pronotal Foliaceous Mimicry in Hierodulinae (Mantodea: Mantidae), with Description of a New Species of Rhombodera Burmeister, 1838 from China

“…As of 28 June 2022, about 27 complete or nearly complete mitogenomes of Hierodulinae species have been sequenced since the first mitogenome of Mantodea, Tamolanica tamolana Brancsik, 1897 was obtained [ 15 ]. Mitochondrial phylogenomic studies of Mantodea in the past five years [ 16 , 17 , 18 , 19 , 20 ] have shown generally congruent relationships compared to the current classification in derived Heteromantodea.…”
