Reconstruction of body mass evolution in the Cetartiodactyla and mammals using phylogenomic data

open access: yesPeer Community Journal, 2021
Reconstructing ancestral characters on a phylogeny is an arduous task because the observed states at the tips of the tree correspond to a single realization of the underlying evolutionary process.

Better tolerance to Huanglongbing is conferred by tetraploid Swingle citrumelo rootstock and is influenced by the ploidy of the scion

open access: yesFrontiers in Plant Science, 2022
Huanglongbing (HLB) is a disease that is responsible for the death of millions of trees worldwide. The bacterial causal agent belongs to Candidatus Liberibacter spp., which is transmitted by psyllids.

Bone Remodeling Process Based on Hydrostatic and Deviatoric Strain Mechano-Sensing

open access: yesBiomimetics, 2022
A macroscopic continuum model intended to provide predictions for the remodeling process occurring in bone tissue is proposed. Specifically, we consider a formulation in which two characteristic stiffnesses, namely the bulk and shear moduli, evolve ...

Mutational induction in SARS-CoV-2 major lineages by experimental exposure to neutralising sera

open access: yesScientific Reports, 2022
The ongoing evolution of SARS-CoV-2 and the emergence of new viral variants bearing specific escape mutations responsible for immune evasion from antibody neutralisation has required a more accurate characterisation of the immune response as one of the ...

PlasForest: a homology-based random forest classifier for plasmid detection in genomic datasets

open access: yesBMC Bioinformatics, 2021
Background Plasmids are mobile genetic elements that often carry accessory genes, and are vectors for horizontal transfer between bacterial genomes. Plasmid detection in large genomic datasets is crucial to analyze their spread and quantify their role in

Filling the Gaps in Biophysical Knowledge of Urban Ecosystems: Flooding Mitigation and Stormwater Retention

open access: yesLand, 2023
Urban flooding is one of the most recognized problems cities must tackle in the coming decades due to climate change conditions. Nevertheless, the empirical knowledge of the biophysical capacity of cities to absorb, store or retain and release water ...

The mechanical characterization of the legs, fangs, and prosoma in the spider Harpactira curvipes (Pocock 1897)

open access: yesScientific Reports, 2022
The exoskeleton of spiders is the primary structure that interacts with the external mechanical stimuli, thus playing a crucial role in spider life.

Antarctic Sphingomonas sp. So64.6b showed evolutive divergence within its genus, including new biosynthetic gene clusters

open access: yesFrontiers in Microbiology, 2022
IntroductionThe antibiotic crisis is a major human health problem. Bioprospecting screenings suggest that proteobacteria and other extremophile microorganisms have biosynthetic potential for the production novel antimicrobial compounds.

Surface growth of Pseudomonas aeruginosa reveals a regulatory effect of 3-oxo-C12-homoserine lactone in the absence of its cognate receptor, LasR

open access: yesmBio, 2023
Successful colonization of a multitude of ecological niches by the bacterium Pseudomonas aeruginosa relies on its ability to respond to concentrations of self-produced signal molecules. This intercellular communication system known as quorum sensing (QS)
