Summary: In this study, a computational toolbox called HGTphyloDetect was developed, which combines high-throughput analysis with phylogenetic inference to accurately identify horizontal gene transfer (HGT) events and illustrate the transmission pathway among evolutionarily distant or closely related species. The HGTphyloDetect toolbox is user-friendly, capable of detecting HGT events with high efficiency and low false discovery rate.

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.

Summary: The study investigated the functional characterization of the ZmLOX4 gene to uncover its strategic role in maize resistance against Fusarium verticillioides, as well as its influence on the expression of several LOX, jasmonic acid (JA) and green leaf volatiles (GLV) genes. The results suggest that ZmLOX4 plays a crucial role in controlling defense against F. verticillioides and modulating the expression of key genes involved in plant defense mechanisms.

Summary: This study investigates the occurrence of horizontal gene transfer (HGT) between Mycobacterium tuberculosis (Mtb) and other mycobacterial species, and its contribution to antibiotic resistance in Mtb. The findings suggest that while HGT occurs in the Mtb complex, antibiotic resistance in Mtb is primarily acquired through mutations in drug-targeted genes within the Mtb complex.

Summary: Ellagic acid and isoeugenol were identified as the most effective natural phenolic compounds for inhibiting fungal growth and reducing toxin production in maize contaminated with Fusarium verticillioides. Proper dosages of these compounds are crucial to prevent conditions that promote mycotoxin biosynthesis. These phenolic compounds modulate biosynthesis at the transcription level in different ways depending on the strain.

Summary: The study reveals that genes encoding the EET system MtrCAB are widespread in diverse bacteria, highlighting the ubiquity and potential impact of EET in our biosphere. These genes have been mainly disseminated through horizontal transfer, with changes observed in different lineages indicating adaptations to changing environments.

Summary: Some bacteria and archaea have evolved the ability to use extracellular electron transfer (EET) as a means of energy metabolism. The MtrCAB system, which transfers electrons from metabolic substrates to electron acceptors outside the cell, has been found in a diverse range of bacteria. These findings highlight the broad relevance of EET to different taxa and biogeochemical cycles in our biosphere and provide a foundation for further research on its evolution and role in Earth's redox landscape.

Summary: This study aimed to explore the impact of different disinfectants on the horizontal transfer of antibiotic resistance genes (ARGs) and their underlying mechanisms. The results showed that quaternary ammonium salt, organic halogen, alcohol, and guanidine disinfectants significantly facilitated the conjugative transfer, while heavy metals, peroxides, and phenols displayed an inhibitory effect. Furthermore, guanidine disinfectants promoted conjugation through increased cell membrane permeability, over-production of reactive oxygen species (ROS), enhanced SOS response, and altered expression of conjugative transfer-related genes. Moreover, guanidine disinfectants also promoted bacterial energy metabolism and flagellum motility. These findings highlight the potential risks caused by the massive use of guanidine disinfectants, especially during the COVID-19 pandemic.

Summary: Cells can acquire mitochondrial DNA (mtDNA) from other cells without a parent-offspring relationship, and this acquisition can occur at high levels. The transfer of mtDNA may serve as a compensatory mechanism to restore compromised mitochondrial function. These findings have important implications for understanding mtDNA transfer and developing gene therapies.

Summary: The genus Fusarium includes pathogens that are of global concern to animal and plant health. Analysis of PKS genes in the genomes of Fusarium species revealed the potential of different clades of PKSs to produce structurally distinct polyketide-derived natural products. This highlights the diverse natural product potential of Fusarium and its ability to produce metabolites with medical and other applications.

Summary: The study found that climate change will increase the co-occurrence of Fusarium verticillioides and Aspergillus flavus, along with their mycotoxins, in European maize. Different temperature regimes affect gene expression and mycotoxin production in maize kernels, with reduced toxin production observed in the case of fungal co-occurrence.

Summary: This study focused on sequencing the genomes of two Phytophthora species to reconstruct phylogenetic relationships within the genus and identify genomic features associated with infection and pathogenicity. The research found that some Phytophthora genes may be inherited from red algae, while horizontally-transferred genes are largely transposons facilitating gene recombination. The study also highlighted expansion events in Phytophthora gene families linked to cell wall biogenesis, which can serve as mutational targets for understanding gene function in pathogenic interactions with host plants and guiding phytopathological control strategies.

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.
