There is a dwindling number of trained taxonomists across the globe, which is part of the "taxonomic impediment" to biodiversity discovery and conservation. Therefore, there is a need to train students in taxonomy and simultaneously …
Read PDF<b>Background</b>: Orchids of the <i>Masdevallia</i> genus are characterized by their beautiful esthetic qualities. However, they are vulnerable to habitat destruction, illegal harvesting, tourism and climate change. These extinction threats have led to the listing of …
Read PDFPhylogenetic branch lengths are essential for many analyses, such as estimating divergence times, analyzing rate changes, and studying adaptation. However, true gene tree heterogeneity due to incomplete lineage sorting, gene duplication and loss, and horizontal …
Read PDFPathogen emergence and adaptation are constant, but the mechanisms underlying pathogen success as well as host susceptibility and resistance are often only observable in time series data. Ancient DNA research of pathogens and their hosts …
Read PDFThe Polygonati Rhizoma have generated significant market attention for their medicinal and culinary applications. However, morphological similarities and ambiguous species boundaries complicate the identification of genera and species, thereby impeding product development and utilization within …
Read PDFSoluble epoxide hydrolase (sEH) is essential for converting epoxy fatty acids, such as epoxyeicosatrienoic acids (EETs), into their dihydroxy forms. EETs play a crucial role in regulating blood pressure, mediating anti-inflammatory responses, and modulating pain, …
Read PDFHorizontal Gene Transfer (HGT) is a hallmark of the evolution of parasitic plants, facilitated by the haustorial connection. While mitochondrial HGT is widespread, the extent of nuclear HGT and the long-term retention of foreign genetic …
Read PDFOver the past 10,000 years, the development of civilization has been enabled by the domestication of plants and animals tailored to human needs. The Triticeae tribe, including barley and wheat, has emerged as one of …
Read PDFIn terrestrial forested ecosystems, fungi may interact with trees in at least three distinct ways: (i) associated with roots as symbionts; (ii) as pathogens in roots, trunks, leaves, flowers, and fruits; or (iii) decomposing dead …
Read PDFThe genus <i>Vibrio</i> encompasses globally relevant pathogens, of which <i>Vibrio cholerae</i> is the best known due to its role in cholera. Closely related species within the Cholerae clade <i>- Vibrio paracholerae</i>, <i>Vibrio metoecus</i> and <i>Vibrio …
Read PDFWeevils represent one of the most prolific radiations of beetles and the most diverse group of herbivores on land. The phylogeny of weevils (Curculionoidea) has received extensive attention, and a largely satisfactory framework for their …
Read PDFA novel, strictly anaerobic, slightly alkaliphilic, halotolerant, peptide- and amino acid-utilizing bacterial strain, SD1<sup>T</sup>, was isolated from a hypersaline lake in Western Australia. The strain stained Gram-negative and was a motile, spore-forming rod. The strain …
Read PDFThe deep sea remains a major reservoir of underexplored microbial diversity and biosynthetic novelty. Here, we describe three bacterial species isolated from Atlantic sponges, including <i>Stappia quadratibracata</i> sp. nov., <i>Bacillus crepusculi</i> sp. nov., and <i>Psychrobacter …
Read PDFHere, we re-examine the high level phylogeny of <i>Pezizomycotina</i> with special attention to the recently proposed phylogenomic hypothesis (Díaz-Escandón et al. 2022) that "morphologically hyperdiverse" <i>Candelariomycetes</i>, <i>Coniocybomycetes</i>, <i>Geoglossomycetes</i>, <i>Lichinomycetes</i>, <i>Sareomycetes</i> and <i>Xylonomycetes</i> (henceforth referred to …
Read PDFThe evolutionary relationships among decapodiform lineages (cuttlefish and diverse types of squid) remain uncertain, with implications for the origin of internalized structures (for example, gladius, cuttlebone and coiled shell) derived from the ancestral chambered shell …
