A more significant role for insertion sequences in large-scale rearrangements in bacterial genomes
Published 2025-01-01“…However, an IS at the center of a large-scale duplication is not readily explained, suggesting that IS element activity may promote both large-scale deletions and duplications.IMPORTANCEInsertion sequences are the most common mobile genetic elements found in bacterial genomes, and hence they significantly impact bacterial evolution. …”

Evolutionary Dynamics and Functional Conservation of <i>amh</i> Signaling in Teleost Lineages
Published 2025-07-01“…The anti-Müllerian hormone (<i>amh</i>) and its receptor, <i>amhr2</i>, along with the downstream bone morphogenetic protein receptors (<i>bmpr</i>s), have been recognized as the central regulators in teleost sex determination (SD) and differentiation. However, their evolution and function in reproduction among diverse teleost lineages may represent species-specific patterns and still need more explanation. …”

Complete sequencing of the mitochondrial genome of tea plant Camellia sinensis cv. ‘Baihaozao’: multichromosomal structure, phylogenetic relationships, and adaptive evolutionary an...
Published 2025-06-01“…Tandem repeats exhibited significant distribution heterogeneity among chromosomes. Adaptive evolution analysis showed that most PCGs (protein-coding genes) had Ka/Ks ratios below 1 (ranging from 0.07 to 0.78), with the atp9 gene showing the lowest ratio (0.07), while the mttB gene exhibited a significantly higher Ka/Ks ratio of 3.48. …”

Tidal Spin-up of Black Hole Progenitor Stars
Published 2023-01-01“…In this work, we investigate this scenario by directly calculating the tidal excitation of oscillation modes in WR star models, determining the tidal spin-up rate, and integrating the coupled spin–orbit evolution for WR–BH binaries. We find that, for short-period orbits and massive WR stars, the tidal interaction is mostly contributed by standing gravity modes, in contrast to Zahn’s model of traveling waves, which is frequently assumed in the literature. …”

Published 2024-08-01“…Caraíba, Vermelhos, Surubim, Terra do Sal, Angicos, Sussuarana are the most prominent of these deposits. The Caraíba Cu-Orebody, so far the most important of all, is part of a body of Archean hypersthenites and norites that underwent poly-deformation and granulitization in the roots of the Paleoproterozoic Itabuna-Salvador-Curaçá orogen, which records the continental collisions responsible for building the São Francisco-Congo paleocontinent in Rhyacian times, ca 2.0 Ga ago. …”

The evolution of Vp1 gene in enterovirus C species sub-group that contains types CVA-21, CVA-24, EV-C95, EV-C96 and EV-C99.
Published 2014-01-01“…The results suggest that permanent fixation of type-specific amino acids is a hallmark associated with evolution of different enterovirus types, whereas neutral evolution and/or (frequency-dependent) positive selection in few highly polymorphic amino acid sites are the dominant forms of evolution when strains within an enterovirus type are compared.…”
