<h4>Premise</h4>We conducted population genetic and phylogenomic analyses of several cultivated Piper nigrum varieties and closely related species. We sought to establish (1) the genetic constitution of P. nigrum and its putative status as an allotetraploid …
Read PDF<h4>Aim of the study</h4>Genomic resources for thermophilic cyanobacteria remain limited, hindering understanding of their ecology and adaptations to extreme high-temperature environments. This study characterizes the genomic features of thermophilic cyanobacteria from thermal springs, focusing on …
Read PDFPhylogenetic trees and networks play a central role in biology, bioinformatics, and mathematical biology, and producing clear, informative visualizations of them is an important task. We present new algorithms for visualizing rooted phylogenetic networks in …
Read PDF<h4>Background</h4>Triacylglycerol lipases (E.C. 3.1.1.3) are serine hydrolases, universally present in animals, plants and microbes and are an integral part of lipid metabolism. They are industrially relevant enzymes that cleave ester bonds of triacylglycerides to release …
Read PDFTwo bacterial strains, designated BSP-53<sup>T</sup> and BSP-153<sup>T</sup>, were isolated from soil samples collected from Beijing Olympic Forest Park, China. Phylogenomic reconstruction based on core genes robustly positioned the strains as two distinct evolutionary lineages within …
Read PDFA thorough understanding of adaptation and speciation requires model organisms with both a history of ecological and phenotypic study as well as a complete set of genomic resources. In particular, high-quality genome assemblies of ecological …
Read PDF<h4>Background</h4>Dengue, a mosquito-borne virus continues to be a public health concern in the tropics and subtropical parts of Africa. Due to the increase of urbanization, climate change and trans-Atlantic trade, the transmitting vector, Aedes aegypti, …
Read PDFBiomineral-associated proteins, such as those found in bone, teeth, and eggshell, have become instrumental for studying ancient life, as they often survive far longer than DNA. Harnessing advancements in avian genomics, we annotate bone and …
Read PDFEukaryotic phototrophs depend on the activity of two engines (the plastid and the mitochondrion) to generate the energy required for cellular metabolism. Because of their overlapping functions, both activities must be closely coordinated. At the …
Read PDFFusarioid fungi, members of the <i>Nectriaceae</i> within the <i>Hypocreales</i> (<i>Ascomycota</i>), exhibit diverse ecological roles and possess complex phylogenetic relationships, including endophytic, saprophytic, and pathogenic lifestyles. Among them, the genera <i>Fusarium</i> and <i>Neocosmospora</i> are particularly significant …
Read PDFParacidovorax citrulli is the causative agent of bacterial fruit blotch in melons and watermelons. This study used comparative genomic approaches of 17 Brazilian P. citrulli strains obtained from melons and watermelons to classify them into …
Read PDFTwo yeast isolates from passion flowers were sampled in the southern part of the Serra do Mar Atlantic Rainforest in Sao Paulo State, Brazil. Barcode sequencing and mating experiments showed them to be representatives of …
Read PDFMembers of the class <i>Campylobacteria</i> are microaerophilic bacteria widely distributed across diverse environments and are abundant in hydrothermal systems. However, cultivated representatives, particularly from shallow-water vents, remain limited. Here, we investigated the genomic diversity and …
Read PDFThe Pottiaceae family represents one of the most diverse and ecologically adaptable bryophytes; however, its chloroplast genome diversity remains largely unexplored. This study aimed to investigate plastome variation and identify evolutionary informative loci within the …
Read PDFHybridization has been recognized to play important roles in evolution, however studies of the genetic consequence are still lagging behind in vertebrates due to the lack of appropriate experimental systems. Fish of the genus Xiphophorus …
Read PDFA new level of viral complexity has emerged from the isolation of green algae-infecting chloroviruses from diverse aquatic environments around the world over the past few decades. This study focuses on describing and comparing the …
Read PDFExtracellular contractile injection systems (eCISs) are bacteriophage tail-derived toxin delivery complexes in prokaryotes. They play roles in microbial interactions with hosts, using tail fiber proteins for target cell binding. Here, we present a comprehensive analysis …
