Arthropod Systematics & Phylogeny, Journal Year: 2025, Volume and Issue: 83, P. 3 - 13

Published: Jan. 23, 2025

Scorpions, a diverse group of arachnids consisting over 2,000 valid species, have received limited research attention in terms their complete mitochondrial genomes (mitogenomes). To increase the taxonomic sampling frequency species available for study based on mitogenomes, we reconstructed mitogenomes five scorpions, Androctonus amoreuxi (Audouin, 1826), Hottentotta tamulus (Fabricius, 1798), Leiurus quinquestriatus (Ehrenberg, 1828), Lychas mucronatus and ­ Teruelius flavopiceus (Kraepelin, 1900) within family Buthidae . These had typical circular structure, with total sizes ranging from 14,504 to 15,083 bp. Nucleotide composition analysis indicated that sequences were biased toward A T. The Ka/Ks ratios 13 protein-coding genes (PCGs) lower than 1, suggesting they been subject purifying selection Our analyses provide additional evidence that, majority mitogenome rearrangements occurred tRNAs. Moreover, tRNA-Asp , tRNA-Gln tRNA-Ile hotspots rearrangement this order. ­Phylogenetic PCGs supported relationships taxon. results might useful insights into gene arrangement features scorpion lay foundation further studies Buthidae.

A Comparative Analysis of Mitogenomes in Species of the Tapinoma nigerrimum Complex and Other Species of the Genus Tapinoma (Formicidae, Dolichoderinae)

Insects, Journal Year: 2024, Volume and Issue: 15(12), P. 957 - 957

Published: Dec. 2, 2024

Using next-generation sequencing data, the complete mitogenomes of six species from genus Tapinoma were assembled. This study explores mitochondrial genomes species, among them five nigerrimum complex, comparing with each other and Dolichoderinae subfamily to understand their evolutionary relationships evolution. contain typical set 13 protein-coding genes, two ribosomal RNA 22 transfer RNAs, A + T-rich control region. phylogenetic analysis using gene sequences available supports monophyletic nature Tapinoma, T. complex forming a well-supported clade. Key findings include genetic traits unique such as start codon in atp8 stop cox1, distinguishing species. Additionally, rearrangement involving tRNA-Trp, tRNA-Cys, tRNA-Tyr was found exclusively suggesting potential marker for genus.

Complete Mitogenome sequencing of the fish louse Argulus japonicus (Crustacea: Branchiura): Comparative analyses and phylogenetic implications

Frontiers in Veterinary Science, Journal Year: 2024, Volume and Issue: 11

Published: March 25, 2024

The fish louse Argulus japonicus , a branchiuran crustacean of the Argulidae family, is attracting increasing attention because its parasitic tendencies and significant health threats to global farming. mitogenomes can yield foundation for studying epidemiology, genetic diversity, molecular ecology therefore may be used assist in surveillance control A. . In this study, we sequenced assembled complete mitogenome shed light on evolutionary blueprint. Our investigation indicated that 15,045-bp circular genome encodes 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), 2 ribosomal (rRNAs) with AT GC skews. Comparative genomics provided an scenario diversity PCGs: all were under purifying selection, cox1 nad6 having lowest highest rates, respectively. Genome-wide phylogenetic trees established close relationship between species families (Arguloida) Armilliferidae (Porocephalida) within Crustacea, further, americanus determined more closely related each other than others family Argulidae. Single PCG-based phylogenies supported nad1 as best markers studies crustaceans due their similar topologies those genome-based analyses. To sum up, these comprehensive mitogenomic data refine valuable marker resources should contribute diagnostic methods, epidemiological investigations, ecological ectoparasites Crustacea.

New mitochondrial genomes of three whip spider species from the Amazon (Arachnida, Amblypygi) with phylogenetic relationships and comparative analysis

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Nov. 1, 2024

The complete mitochondrial genomes of the whip spiders Charinus carajas, C. ferreus, and Heterophrynus longicornis were sequenced, annotated, compared with other mitogenomes arachnids. three new have 37 genes usually observed in Metazoa: 13 protein-coding (PCGs), 22 transfer RNAs (tRNAs), two ribosomal (rRNAs), plus a non-coding control region (CR). Most PCGs presented an ATN start codon, except cox1 both species, initiating TTA. terminated stop codons TAA or TAG, nad5 carajas cox3 H. longicornis, which incomplete codon (T). Ka/Ks ratios less than one for all PCGs, indicating these are under purifying selection. All tRNAs, serine 1 (trnS1), had typical cloverleaf-shaped secondary structure. phylogenetic analyses resolved ferreus as monophyletic groups. Nonetheless, we did not recover monophyly longicornis. phylogenies partitioned models suprageneric taxonomic groups clades, but Bayesian inference CAT infinite mixture model recovered family Phrynidae superfamily Phrynoidea
