The taxonomic status of many Southern European taxa of the <i>Ranunculus auricomus</i> complex remains uncertain despite this region's proximity to the native ranges of the sexual progenitor species of the complex. We investigated whether additional …
Read PDF<h4>Premise</h4>Hybridization and introgression are pervasive evolutionary forces that have played fundamental roles in shaping the diversity of wild and domesticated plants. Four-taxon tests for introgression provide a reliable framework for detecting signatures of ancient introgression …
Read PDFThe topologies of gene trees are broadly used to infer horizontal gene transfer events and characterize the potential donor and acceptor partners. Additionally, ratios between branch lengths in the gene tree can inform about the …
Read PDFConvolvulaceae, the morning glories or bindweeds, is a large family containing species of economic value, including crops, traditional medicines, ornamentals, and vegetables. However, not only are the phylogenetic relationships within this group still debated at …
Read PDFNon-O157 Shiga toxin-producing <i>Escherichia coli</i> (STEC), particularly the O118 serogroup, are emerging pathogens linked to severe foodborne illnesses, which are characterized by the production of a potent phage-borne cytotoxin. This study explores the genomic landscape, …
Read PDFWhile adaptive radiations significantly contribute to the world's biodiversity, much is unknown about the genetic and ecological factors underlying these rapid successions of speciation. It has been suggested that hybridisation can facilitate the speciation process …
Read PDFSpecialized metabolites are central to plant defense, signaling and ecological interactions, yet we still lack a macroevolutionary framework explaining how this diversity is structured across angiosperms. Here, we integrate the open LOTUS chemical repository with …
Read PDFThe phylum Heterolobosea comprises a morphologically diverse and ecologically versatile assemblage of free-living microbial eukaryotes, yet genus-level boundaries remain difficult to resolve due to limited diagnostic characters and extensive phenotypic plasticity. Here, we apply a …
Read PDFHybridization is widespread across diverse groups of organisms, and in some cases, organellar genomes of one species become fixed in another following hybridization and backcrossing, a phenomenon known as organelle capture. Because cytoplasmic genomes can …
Read PDFSynchronizing mating to extrinsic environmental cycles can increase the chance of successful reproduction, and the resulting temporally-assorted mating may precipitate speciation if coupled with divergent selection. This process might be particularly relevant to the marine …
Read PDFConcerted gains and losses of genomic features such as genes and mobile genetic elements can provide key clues into related functional roles and shared evolutionary trajectories. By capturing phylogenetic signals, a coevolutionary model can outperform …
Read PDFFor a set of binary unrooted subtrees generating all binary unrooted trees compatible with them, i.e. generating their stand, is one of the classical problems in phylogenetics. Here, we introduce Gentrius-an efficient algorithm to tackle …
Read PDFThalasseus bernsteini (Chinese crested tern), known as the rarest tern in the world, has become critically endangered with a severely diminished population. Understanding its genetic diversity is crucial for conservation efforts. However, no genomic resource …
Read PDFNext-generation sequencing technologies are revolutionizing the fields of genomics, phylogenetics, and population genetics. These new genomic approaches have been extensively applied to a major group of parasites, the lice (Insecta: Phthiraptera) of birds and mammals. …
Read PDF<b>Background.</b> Rates of multidrug resistance (MDR) in Gram-negative bacteria (GNB), particularly those harbouring extended-spectrum beta-lactamases (ESBL) and/or carbapenemases, are increasing globally. Intensive care unit (ICU) patients are vulnerable to healthcare-associated infection (HCAI). Surveillance for carriage …
Read PDF<h4>Introduction</h4>The "<i>Saccharum</i> complex" comprises several closely related genera (<i>Tripidium/Erianthus</i>, <i>Miscanthus</i> and <i>Narenga</i>) which may hybridize with <i>Saccharum</i>, contributing to the origin of modern sugarcane. Sugarcane (<i>Saccharum</i> spp.) has one of the most complex crop genomes, …
Read PDFThe allotetraploid wild grass Aegilops ventricosa (2n = 4x = 28, genome D<sup>v</sup>D<sup>v</sup>N<sup>v</sup>N<sup>v</sup>) has been recognized as an important germplasm resource for wheat improvement owing to its ability to tolerate biotic stresses. In particular, the …
Read PDFHerpesvirus infections, including herpes simplex virus (HSV), Epstein-Barr virus (EBV), and cytomegalovirus (CMV), present significant challenges in diagnosis, treatment, and transmission control. Despite advances in medical technology, managing these infections remains complex due to the …
Read PDFBacteriocins are antimicrobial peptides produced by different species of bacteria, especially the Gram-positive lactic acid bacteria (LAB). <i>Pediococcus pentosaceus</i> is widely applied in the industry and stands out as Bacteriocin-Like Inhibitory Substances (BLIS) producer known …
