Ítem A Comparative Analysis of Mitogenomes in Species of the Tapinoma nigerrimum Complex and Other Species of the Genus Tapinoma (Formicidae, Dolichoderinae)(MDPI, 2024-12-02) Ruiz-Mena, Areli; Mora, Pablo; Rico-Porras, José M.; Kaufmann, Bernard; Seifert, Bernhard; Palomeque, Teresa; Lorite, PedroUsing next-generation sequencing data, the complete mitogenomes of six species from the genus Tapinoma were assembled. This study explores the mitochondrial genomes of Tapinoma species, among them the five species from the Tapinoma nigerrimum complex, comparing them with each other and with other species from Dolichoderinae subfamily to understand their evolutionary relationships and evolution. Tapinoma mitochondrial genomes contain the typical set of 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNAs, and the A + T-rich control region. A phylogenetic analysis using the protein-coding gene sequences from available Dolichoderinae mitogenomes supports the monophyletic nature of the genus Tapinoma, with the T. nigerrimum complex forming a well-supported clade. Key findings include genetic traits unique to the T. nigerrimum complex, such as a start codon in the atp8 gene and a complete stop codon in cox1, distinguishing them from other Tapinoma species. Additionally, a gene rearrangement involving tRNA-Trp, tRNA-Cys, and tRNA-Tyr was found exclusively in the Tapinoma species, suggesting a potential phylogenetic marker for the genus.Ítem Complex Evolutionary Histor of Mboumar, a Mariner Element Widely Represented in Ant Genomes(Nature Research, 2020-02) Sanllorente, Olivia; Vela, Jesús; Mora, Pablo; Ruiz-Mena, Areli; Torres, María Isabel; Lorite, Pedro; Palomeque, TeresaThis study examines the mariner-like transposable element Mboumar, previously identified in the ant Messor bouvieri, across 22 ant species from nine subfamilies, including both primitive and derived lineages. The widespread presence of Mboumar-like elements in ant genomes is evident, but the phylogenetic relationships of these elements do not align with the evolutionary history of their ant hosts. Genetic analysis revealed conserved transposable elements with uninterrupted open reading frames in 11 species, encoding transposases closely resembling the active Mboumar-9 transposase. Selection tests indicate purifying selection has shaped the evolution of these elements.
