The genus Clostridium is a large and diverse group within the Bacillota (formerly Firmicutes), whose members can encode useful complex traits such as solvent production, gas-fermentation, and lignocellulose breakdown. We describe 270 genome sequences of …
Read PDF<b>Background:</b> Telomeres are nucleoprotein complexes that maintain chromosome integrity in eukaryotes. In insects, the canonical telomeric repeat (TTAGG)<i>n</i> is considered ancestral, though alternative motifs exist across various orders. Neuroptera, comprising about 5800 species, remains understudied …
Read PDFThe cosmopolitan genus <i>Xylaria</i> Hill ex Schrank (Ascomycota, Sordariomycetes), is the largest within the order Xylariales. While <i>Xylaria</i> species primarily exist as saprotrophs, they can also occur as endophytes or as phytopathogens. Specimens of <i>Xylaria</i> …
Read PDFThe phylum Rozellomycota has been proposed for a group of early-branching holomycotan lineages representing obligate parasites and hyperparasites of zoosporic fungi, oomycotes or phytoplankton. Given their predominantly intracellular lifestyle, rozellids are typically known from environmental …
Read PDFThe search for sustainable agricultural solutions to reduce pesticide dependence is urgent, particularly under the growing pressures of climate change. Although Trichoderma species are well-known biocontrol agents, many strains perform poorly in extreme soils characterized …
Read PDFThe Carboniferous myriapod <i>Arthropleura</i> is the largest arthropod of all time, but its fossils are usually incomplete, limiting the understanding of its anatomy, ecology, and relationships. Micro-computed tomography applied to exceptionally preserved specimens from the …
Read PDFConnaraceae is a pantropical family of about 200 species containing lianas and small trees with remarkably diverse floral polymorphisms, including distyly, tristyly, homostyly, and dioecy. To date, relationships within the family have not been investigated …
Read PDF<h4>Background</h4>Rare actinomycetes, particularly Gordoni spp., are emerging as critical sources of bioactive metabolites and opportunistic pathogens.<h4>Results</h4>In this study, we isolated three novel Gordonia strains from soil samples and characterized their taxonomic status using a polyphasic …
Read PDFMyxobacteria are Gram-negative, spore-forming predatory bacteria isolated from diverse environmental samples that feed on other microbes for their survival and growth. However, no reports of cultured representatives from the human gut have been published to …
Read PDFMost land plants form the ancient arbuscular mycorrhizal (AM) symbiosis, while carnivory is a younger trait that evolved in several angiosperm orders. The two biotic interactions similarly help plants acquire mineral nutrients, raising the question …
Read PDFThylakoid membranes are the site of oxygenic photosynthesis, one of the most important biochemical processes on earth. The ancestral state of these membranes is represented today in Gloeobacterales, where they are lacking and photosynthesis instead …
Read PDFTrichosporeae is the largest and most taxonomically difficult tribe of Gesneriaceae due to its diverse morphology. Previous studies have not clarified the phylogenetic relationships within this tribe on several DNA markers, including the generic relationships …
Read PDFRoot-knot nematodes (Meloidogyne spp.) are among the most damaging plant-parasitic nematodes, yet taxonomic uncertainties often complicate diagnostics and management. Here, we examined Meloidogyne silvestris populations from the Netherlands using an integrative approach combining morphology, isoenzyme …
Read PDFMutualistic symbioses have contributed to major transitions in the evolution of life. Here, we investigate the evolutionary history and the molecular innovations at the origin of lichens, which are a symbiosis established between fungi and …
Read PDFThe genetic variability of <i>Helicobacter pylori</i> contributes to differences in the severity of gastrointestinal diseases. Within the stomach, <i>H. pylori</i> exhibits diverse strain patterns and genetic variations that enable the evolution of new virulence factors, …
Read PDFMitochondrial genomes offer pragmatic genetic markers to reconstruct evolutionary relationships and inform taxonomic classifications. Here, we present complete mitochondrial sequences for four Chinese pygmy grasshoppers (Tetrigidae), aiming to reevaluate phylogenetic patterns and morphological taxonomy. Our …
Read PDF<i>Docynia</i> has been treated as a separate genus or merged into <i>Cydonia</i> or <i>Docyniopsis</i>. Our phylogenomic evidence from 797 single-copy nuclear genes and plastomes confirmed the sister relationship between <i>Docynia</i> and <i>Docyniopsis</i>. By integrating the …
Read PDFDNA-binding with One Finger (Dof) transcription factors are plant-specific regulators involved in diverse biological processes, including growth, development, and stress responses. However, the Dof family in tobacco (<i>Nicotiana tabacum</i> L.) remains poorly characterized. Here, we …
