Marine algae underpin entire ocean ecosystems. Yet algae in culture poorly represent their large environmental diversity, and we have a limited understanding of their convoluted evolution by endosymbiosis. Here, we perform a phylogeny-guided plastid genome-resolved …
Read PDFYeasts belonging to the Candida genus typically reside on the mucosal surface and within the respiratory and gastrointestinal tract as commensals. Under conditions of host vulnerability, they can act as opportunistic pathogens, leading to various …
Read PDFThe characteristics of the last eukaryotic common ancestor (LECA) population and the root of the eukaryotic tree have been coming into focus lately. However, the trajectory taking the host, related to present-day Asgard archaea and …
Read PDF<h4>Objectives</h4>Critical priority carbapenem-resistant pathogens constitute a worldwide public health problem. Escherichia coli (E. coli) ST1193 is an emerging high-risk clone that demonstrates prolonged gut persistence, and association with community-onset urinary and bloodstream infections. The purpose …
Read PDFPlant-microbiome research plays a pivotal role in understanding the relationships between plants and their associated microbial communities, with implications for agriculture and ecosystem dynamics. Metabarcoding analysis on variable regions of the 16S ribosomal RNA (rRNA) …
Read PDFFounder-event speciation can occur when one or more organisms colonize a distant, unoccupied area via long-distance dispersal, leading to the evolution of a new species lineage. Species radiations established by long-distance, and especially transoceanic, dispersal …
Read PDFTetraopes longhorn beetles are known for their resistance to milkweed plant toxins and their coevolutionary dynamics with milkweed plants (Asclepias). This association is considered a textbook example of coevolution, in which each species of Tetraopes …
Read PDFBrazil has two dog breeds recognized by the Fédération Cynologique Internationale: the Brazilian Terrier and the Brazilian Mastiff. The Brazilian Terrier is believed to descend from Jack Russell Terriers crossed with local strays and possibly …
Read PDFShotgun metagenomics has become a pivotal technology in microbiome research, enabling in-depth analysis of microbial communities at both the high-resolution taxonomic and functional levels. This approach provides valuable insights of microbial diversity, interactions, and their …
Read PDFThe stingless bee <i>Meliplebeia beccarii</i>, endemic to Ethiopia, plays a crucial ecological and economic role through pollination and high-quality honey production. However, habitat degradation and anthropogenic pressures threaten its survival. In this study, we present …
Read PDFIn recent years, there has been a growing interest in using morphology to establish the placement of species on phylogenetic trees derived from molecular data. This is relevant in the case of recently extinct or …
Read PDFBone extracellular matrix (ECM) proteins play a key role in bone formation and regeneration, including structural and regulatory functions. The Phylobone database consists of 255 ECM protein groups from 39 species and can be used …
Read PDFHybridization is common and considered as an important evolutionary force to increase intraspecific genetic diversity. Detecting hybridization events is crucial for understanding the evolutionary history of species and further improving molecular breeding. The studies on …
Read PDFOryza is a remarkable genus comprising 27 species and 11 genome types, with ~3.4-fold genome size variation, that possesses a virtually untapped reservoir of genes that can be used for crop improvement and neodomestication. Here …
Read PDFClassification of gene trees is an important task both in the analysis of multi-locus phylogenetic data, and assessment of the convergence of Markov Chain Monte Carlo (MCMC) analyses used in Bayesian phylogenetic tree reconstruction. The …
Read PDFThe genus <i>Lathyrus</i> L. (Fabaceae) is represented in Belgium by several native and alien species, amongst which the <i>Lathyrus sylvestris</i>-latifolius complex has long posed taxonomic difficulties. Since the 1940s, plants with intermediate morphological characters between …
Read PDF<b>Background:</b> The shift to a parasitic lifestyle in plants often leaves distinct marks on their plastid genomes, given the central role plastids play in photosynthesis. Studying these unique adaptations in parasitic plants is essential for …
Read PDFHigh levels of intra-specific polymorphism and frequent hybridisation make it difficult to define species and correctly apply their scientific names. <i>Populus</i> L. is a challenging genus with plentiful natural and artificial hybrids. This study is …
Read PDFA new ant species, <i>Messor odrysarum</i> <b>sp. nov</b>., of the <i>Messor structor</i> species group, is described based on worker, gyne and male castes collected in Eastern Rhodopes, Bulgaria. The description is supported by the morphology …
Read PDF<h4>Introduction</h4>The genus <i>Acronema</i>, belonging to Apiaceae, includes approximately 25 species distributed in the high-altitude Sino-Himalayan region from E Nepal to SW China. This genus is a taxonomically complex genus with often indistinct species boundaries and …
