Summary: Graphene quantum dots (GQDs) and antibiotic resistance genes (ARGs) coexist in the environment. This study investigates the influence of GQDs on the horizontal transfer of ARGs mediated by plasmids into Escherichia coli cells. GQDs enhance ARG transfer at lower concentrations, but weaken or inhibit the transfer at higher concentrations due to aggregation and hindering of ARG entrance. This study provides understanding of the ecological risks caused by GQDs and their safe application.

Summary: This review discusses key studies on current models for bacterial conjugation in the gut, including in silico, in vitro, and in vivo models. The importance of studying plasmid transfer in the gut is emphasized, as it plays a significant role in the emergence and spread of antimicrobial resistance and virulence genes. The review highlights the need for alternate models that accurately represent the gut environment and provides directions for future research.

Summary: This study aimed to quantify and identify new plasmid-acquiring bacteria resulting from manure application to soils to assess the risk of horizontal gene transfer in the environment. The results showed that gene transfer from fecal to soil bacteria occurred despite suboptimal conditions, but these events were rare and mainly happened shortly after manure application, with the plasmid not colonizing the soil community.

Summary: This study shows that dead bacteria and their extracellular antibiotic resistance genes (eARGs) can facilitate the spread of antibiotic resistance in soil. The transformation of eARGs to live bacteria occurred even at low concentrations and under typical soil moisture conditions. However, very high soil moistures inhibited the transformation process. This research highlights the importance of considering the role of dead bacteria and eARGs in the evolution of antibiotic resistance in the environment.

Summary: Horizontal gene transfer is an important factor in bacterial evolution, allowing for rapid evolution and increased adaptation in recipient organisms. Adaptive evolution mainly occurs in populations with increased fitness, with HGT selection having a broad genetic basis and showing different types of selection in functional gene networks.

Summary: Inhibition of plasmid transfer can prevent the spread of plasmid-encoded antimicrobial resistance. Photosensitizers have been found to significantly reduce the transformation and conjugation efficiency of plasmids, thereby mitigating the dissemination of antibiotic resistance genes.

Summary: Very little is known about the horizontal transfer of antibiotic resistance genes in aquacultural environments through microbiome interactions. This study conducted amplicon sequencing and co-occurrence analysis to monitor bacterial community dynamics and reveal interactions between Vibrio spp. and other species. Whole-genome sequencing was performed to understand the sharing of resistant genomic islands (GIs) in selected isolates. The analysis identified horizontally transferred genes associated with antibiotic resistance, virulence, and metabolism fitness. The study highlights the importance of understanding microbiome interactions in aquacultural settings for predicting and mitigating the emergence of new resistant populations.

Summary: Protein posttranslational modifications add complexity to biological systems. This study reveals the evolutionary trajectory of peptidylarginine deiminases (PADIs) in animals and provides evidence that PADIs were introduced into animals through horizontal gene transfer from cyanobacteria.

Summary: Antimicrobial resistance in the environment has become a critical issue, and nanomaterial-mediated dissemination of antibiotic resistance genes (ARGs) is receiving increasing attention. This study investigates the impact of graphene oxide (GO) transformation on ARGs horizontal transfer. It is found that light-reduced GO significantly enhances the transfer of plasmid-borne ARGs, while GO reduced by ferrous iron attenuates this facilitation. Additionally, the transconjugant strain formed through GO-mediated conjugation exhibits higher macrophage infection under antibiotic treatment.

Summary: Horizontal gene transfer (HGT) is a key force in microbial evolution, with long-distance HGT being frequent. The function of sequences strongly impacts their transfer rate, varying significantly between different functional categories. This study provides a comprehensive view of HGT and its role in driving bacterial evolution.

Summary: In this study, a three-dimensional finite element dynamics model of the drill-string is established, taking into consideration the dynamic friction model and buckling effect. The modified dynamics model is verified to have higher computational accuracy through laboratory experiments. A parameter study is conducted based on the dynamics model, revealing significant effects of the exciting force amplitude, drilling fluid density, axial force, friction coefficient, and drill-string dimension on the friction reduction performance and effective propagation distance of axial vibration. A prediction model for vibration propagation distance is established, enabling efficient optimization of axial vibration parameters in horizontal well drilling. This study can provide theoretical guidance for safely and efficiently reducing sliding friction in the exploitation of unconventional oil and gas reservoirs.

Summary: Animal venoms have evolved through recruitment of endogenous proteins with physiological functions, with centipedes being the only known animals with venoms containing gene families derived from horizontal gene transfer events. Horizontal gene transfer serves as a fast track channel for the evolution of novelty in animal venoms.
