Production of antibacterial compounds by a Steely hybrid polyketide synthase in Dictyostelium

open access: yesFEBS Open Bio, EarlyView.
By selecting appropriate production species under optimised culture conditions, new chlorinated dibenzofuran compounds, which previously could not be analysed in sufficient quantities, were identified from cellular slime mould fruiting bodies. The strong antibacterial activity exhibited by these compounds suggests a link to the ecological function of ...

Evolutionary dynamics of the chloroplast genome in Daphne (Thymelaeaceae): comparative analysis with related genera and insights into phylogenetics

open access: yesFEBS Open Bio, EarlyView.
Comparative analysis of chloroplast genomes from 14 genera of Thymelaeaceae revealed variation in gene content, ranging from 128 to 142 genes, primarily influenced by IR expansion/contraction events and pseudogenization of ndhF, ndhI, and ndhG. Two large inversions were detected within the large single‐copy region, including a synapomorphic inversion ...

Quartets enable statistically consistent estimation of cell lineage trees under an unbiased error and missingness model

open access: yesAlgorithms for Molecular Biology, 2023
Cancer progression and treatment can be informed by reconstructing its evolutionary history from tumor cells. Although many methods exist to estimate evolutionary trees (called phylogenies) from molecular sequences, traditional approaches assume the ...

Modeling the Ecology and Evolution of Biodiversity: Introduction to the Special Issue

open access: yesDiversity, 2022
Applying relevant statistical models to empirical data analysis has been considered a very important procedure for scientists to answer research questions in the fields of biodiversity, phylogeography, evolutionary biology, paleoecology, phylogenetics ...

Gelechiidae Moths Are Capable of Chemically Dissolving the Pollen of Their Host Plants [PDF]

open access: yes, 2011
Background: Many insects feed on pollen surface lipids and contents accessible through the germination pores. Pollen walls, however, are not broken down because they consist of sporopollenin and are highly resistant to physical and enzymatic damage. Here

Relapsing–Remitting Multiple Sclerosis Is Associated With a Dysbiotic Oral Microbiome

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Multiple sclerosis (MS) is a chronic autoimmune disorder characterized by inflammation, demyelination, and neurological impairment. While the gut microbiota's role in MS is extensively studied, the association between the oral microbiota and MS remains underexplored, particularly in North American cohorts.

Survey of molecular phylogenetics

open access: yesPlant, Soil and Environment, 2007
Rapidly increasing amount of biological data necessarily requires techniques that would enable to extract the information hidden in the data. Methods of molecular phylogenetics are commonly used tools as well as objects of continuous research within many

Make the most of your samples : Bayes factor estimators for high-dimensional models of sequence evolution [PDF]

open access: yes, 2013
Background: Accurate model comparison requires extensive computation times, especially for parameter-rich models of sequence evolution. In the Bayesian framework, model selection is typically performed through the evaluation of a Bayes factor, the ratio ...

pH‐Tunable Material Properties of Glycine‐Rich Condensates from Tick Bioadhesive

open access: yesAdvanced Functional Materials, EarlyView.
This work studies the influence of pH on the phase separation behavior of a disordered glycine‐rich protein found in tick bioadhesive. The results show profound impact on the propensity of coacervation, condensate microstructure and viscosity, amphiphilicity of the peptides, and effective encapsulation of therapeutic molecules.

Micro and Nanostructural Diversity of Lizard Osteoderm Capping Tissue in Relation to Mechanical Performance

open access: yesAdvanced Functional Materials, EarlyView.
This study shows that lizard osteoderm capping tissue is a hyper‐mineralized hydroxyapatite layer consistently covering the superficial osteoderm surface in those species studied here, yet it varies greatly in morphology, nanostructure, and mechanical performance across species.
