A Perl Package and an Alignment Tool for Phylogenetic Networks [PDF]

open access: yesarXiv, 2007
Phylogenetic networks are a generalization of phylogenetic trees that allow for the representation of evolutionary events acting at the population level, like recombination between genes, hybridization between lineages, and lateral gene transfer. While most phylogenetics tools implement a wide range of algorithms on phylogenetic trees, there exist only

New data on the mammalian fauna from the late middle Eocene (MP 15–16) of Mazaterón (Soria, Spain): The youngest presence of the genus Prodissopsalis (Hyaenodonta, Hyaenodontidae) in Europe

open access: yesThe Anatomical Record, EarlyView., 2023
Abstract The Hyaenodonta were the most diverse carnivorous mammals in the European Eocene and were classically divided into three subfamilies: Sinopaninae, Arfianinae, and Proviverrinae, with this latter being the most successful of the three, as it exhibited a much larger geographic and temporal range.

Evolution‐Guided Discovery of Antimycobacterial Triculamin‐Like Lasso Peptides

open access: yesAngewandte Chemie, EarlyView.
The hypothesized convergent biosynthesis of triculamin‐like lasso peptides from different biosynthetic gene cluster (BGC) types represented across multiple bacterial phyla. The elucidation of the triculamin non‐canonical BGC and resistance mechanism by heterologous expression in Streptomyces albus and in vitro acetylation with resistance conveying ...

Grass functional traits reflect the long history of fire and grazers in the savannas of Texas

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Understanding relationships among grass traits, fire, and herbivores may help improve conservation strategies for savannas that are threatened by novel disturbance regimes. Emerging theory, developed in Africa, emphasizes that functional traits of savanna grasses reflect the distinct ways that fire and grazers consume biomass ...

First clear evidence of Anoplotherium (Mammalia, Artiodactyla) in the Iberian Peninsula: an update on the Iberian anoplotheriines

open access: yesThe Anatomical Record, EarlyView., 2023
Abstract Anoplotheriines (Mammalia, Artiodactyla) were enigmatic, medium‐ to large‐sized ungulates that lived in Western Europe from the late middle Eocene to the earliest Oligocene. The unusual dental and postcranial specializations of these Paleogene mammals have no equivalent in other Cenozoic or contemporaneous artiodactyls on Holarctic landmasses.

Anchor Peptide‐Based Immobilization Strategy Promote the Applications of Pickering Emulsion System in Natural Products Glycosylation

open access: yesAngewandte Chemie, EarlyView.
This study designs an anchor peptide‐based immobilization strategy to expand the application of Pickering emulsion to glycosyltransferases (GTs) for the first time, addressing low conversion challenge in aqueous solutions. The glycosylation Pickering emulsion achieved more than 90% conversion of natural product glycosides with high recyclability ...

Characterization and phylogenetic analysis of the complete mitochondrial genome of Glossogobius giuris (Perciformes: Gobiidae)

open access: yesMitochondrial DNA. Part B. Resources, 2018
The species tank goby (Glossogobius giuris) is assessed as Least Concern on the IUCN Red List of Threatened Species. In the present study, we first determined and described the complete mitochondrial genome of G. giuris.

Phylogenetic Networks Do not Need to Be Complex: Using Fewer Reticulations to Represent Conflicting Clusters [PDF]

open access: yesarXiv, 2009
Phylogenetic trees are widely used to display estimates of how groups of species evolved. Each phylogenetic tree can be seen as a collection of clusters, subgroups of the species that evolved from a common ancestor. When phylogenetic trees are obtained for several data sets (e.g.

Expanding the Tyrosine Kinase Domain of CSF1R? A Case Report From an Adult‐Onset Leukoencephalopathy

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Adult‐onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP), also termed hereditary diffuse leukoencephalopathy with spheroids‐1 (HDLS1), results from mutations in the CSF1R gene and leads to progressive leukoencephalopathy.
