Eukaryotic genes usually encode proteins and contain exons in different size, including micro and small exon categories. However, genome-wide gene exon-intron organizations and their conservation across angiosperms have not been investigated. Among exons of protein-coding …
Read PDFColobognatha, a group of millipedes (Diplopoda) known for their unique biological traits (<i>e.g.,</i> brood care and sociality), is the only group among millipedes to produce terpenoid alkaloids. Before 2020, only four terpenoid alkaloids had been …
Read PDF<h4>Background</h4>Chloranthaceae is a pantropical family of flowering plants distributed mainly across Central and South America, East Asia, and the Pacific, encompassing approximately 73 species belonging to four extant genera-Ascarina, Chloranthus, Hedyosmum, and Sarcandra. As one …
Read PDFLimestone karsts are renowned for extremely high species richness and endemism. <i>Aspidistra</i> (Asparagaceae) is among the highly diversified genera distributed in karst areas, making it an ideal group for studying the evolutionary mechanisms of karst …
Read PDF<h4>Background</h4>Rhodococcus equi is an intracellular bacterial pathogen that can cause infections in various hosts, including humans and animals. Host-associated virulence plasmids have been identified as key contributors to the pathogenicity of R. equi and potentially …
Read PDFActinobacteria associated with medicinal plants are recognized as prolific sources of novel bioactive compounds. Kratom (<i>Mitragyna speciosa</i>) leaves have been reported to contain a diverse array of secondary metabolites with pharmacological activities, including antibacterial, antioxidant, …
Read PDFWith the increasing availability of genomic data, biologists aim to find more accurate descriptions of evolutionary histories influenced by secondary contact, where diverging lineages reconnect before diverging again. Such reticulate evolutionary events can be more …
Read PDF<h4>Background</h4>Microbial culture collections play a key role in taxonomy by studying the diversity of their strains and providing well-characterized biological material to the scientific community for fundamental and applied research. These microbial resource centers thus …
Read PDFThis study aims to delineate the chloroplast (cp) genome of the critically endangered <i>Lithocarpus yongfuensis</i> (Fagaceae), with fewer than 10 wild individuals known. Genomic information for this species is scarce, hindering conservation strategies. We sequenced, …
Read PDFDryopteridaceae are the largest fern family and include nearly 20% of extant fern diversity, with 24 currently recognized genera. Recognition and delineation of genera within this family have varied greatly. The three-subfamily classification of Dryopteridaceae …
Read PDFProsthetic pulmonary valve endocarditis is a rare but serious infective complication following correction of tetralogy of Fallot (ToF). We describe a probable zoonotic case of <i>Streptococcus equi</i> subspecies <i>zooepidemicus</i> prosthetic pulmonary valve infective endocarditis in …
Read PDF<h4>Background</h4>True fruit flies (Diptera: Tephritidae) are among the most destructive pests of fruit and vegetables worldwide and are on the top of quarantine pest lists. To respond effectively to a fruit fly invasion, we need …
Read PDFIn the United Arab Emirates, no previous research has investigated the dynamics of the foodborne pathogen <i>Campylobacter</i> in broiler abattoir processing. This study conducted in one of the largest poultry producers in the UAE, following …
Read PDFThe surge in genome data, with ongoing efforts aiming to sequence 1.5 M eukaryotes in a decade, could revolutionize genomics, revealing the origins, evolution and genetic innovations of biological processes. Yet, traditional genomics methods scale …
Read PDF<b>Background/Objectives</b>: The origin of genes and genetics is the story of the coevolution of translation systems and the genetic code. Remarkably, the history of the origin of life on Earth was inscribed and preserved in …
Read PDFThe Cypripedioideae subfamily (slipper orchids) exhibits remarkable ecological diversity, spanning temperate to tropical habitats, yet the molecular mechanisms underlying its adaptive radiation remain poorly understood. Chloroplast genomes, with their critical roles in photosynthesis and conserved …
Read PDFMetazoan oxidative phosphorylation (OXPHOS) complexes are composed of subunits encoded by mitochondrial and nuclear genes, requiring continuous mitonuclear coevolution to ensure functional compatibility. However, mitochondrial and nuclear genomes exhibit separate inheritance patterns, leading to their …
Read PDF<i>Distoseptispora</i> comprises ecologically significant species that are predominantly saprobic, inhabiting freshwater and terrestrial ecosystems, where they contribute to nutrient cycling and organic matter decomposition. Recent taxonomic studies have revealed several new <i>Distoseptispora</i> species, highlighting its …
Read PDFGenomes are typically mosaics of regions with different evolutionary histories. When speciation events are closely spaced in time, recombination makes the regions sharing the same history small, and the evolutionary history changes rapidly as we …
Read PDF<i>Klebsiella pneumoniae sensu stricto</i> (KpI) is an opportunistic pathogen capable of residing as a commensal in both human and bovine intestinal tracts and can cause serious systemic infections in humans and severe clinical mastitis in …
