Phylogenomics, ecomorphological evolution, and historical biogeography in Deuterocohnia (Bromeliaceae: Pitcairnioideae)

American Journal of Botany, EarlyView.
Abstract Premise Species of Deuterocohnia (17 spp.) show extraordinary variation in elevation (0–3900 m a.s.l.) and growth forms, and many have narrow geographic distributions in the west‐central Andes and the Peru‐Chile coast. Previous research using few plastid and nuclear loci failed to produce well‐resolved or supported phylogenies.

PCA‐Based Database Mining Enables the Discovery of Bacterial Carbene Transferases for Stereodivergent Cyclopropanation

Angewandte Chemie, EarlyView.
Database mining using principal component analysis (PCA)‐based clustering enabled discovery of bacterial enzymes capable of catalyzing stereodivergent cyclopropanation of styrene. Statistical analyses of sequence data further revealed characteristic structural properties of these enzymes, highlighting the potential of the bioinformatics tools for ...

CGRWDL: alignment-free phylogeny reconstruction method for viruses based on chaos game representation weighted by dynamical language model

Frontiers in Microbiology
Traditional alignment-based methods meet serious challenges in genome sequence comparison and phylogeny reconstruction due to their high computational complexity.

Phylogenomics reveals the evolution of floral traits associated with pollinators and pollinator–prey conflict within the carnivorous Pinguicula subgenus Temnoceras

American Journal of Botany, EarlyView.
Abstract Premise The carnivorous plant genus Pinguicula (Lentibulariaceae) exhibits remarkable floral diversity associated with pollination, particularly in the largest subgenus Temnoceras, which spans Mexico and Central America. Despite this diversity, the relationships between species and the evolution of key floral traits remain unresolved. Here, we

Construction of pathogenic Sec16a mutation mouse model using CRISPR/Cas9

Animal Models and Experimental Medicine, EarlyView.
Yaqiang Hu et al. engineered a pathogenic Sec16a mutant mouse model using CRISPR/Cas9 technology. They observed that the Sec16a mutant mice displayed diminished learning and memory capabilities, along with a limb‐clasping phenotype upon tail suspension.

Accurate Bayesian phylogenetic point estimation using a tree distribution parameterized by clade probabilities.

PLoS Computational Biology
Bayesian phylogenetic analysis with MCMC algorithms generates an estimate of the posterior distribution of phylogenetic trees in the form of a sample of phylogenetic trees and related parameters.

Establishment of a biosafe murine model of skeletal tuberculosis using Mycobacterium smegmatis

Animal Models and Experimental Medicine, EarlyView.
This study developed a biosafe, accessible, and versatile murine model of bone TB using Mycobacterium smegmatis, a fast‐growing, nonpathogenic mycobacterial species with high genomic homology to Mycobacterium tuberculosis. Three infection routes—subperiosteal calvarial injection, intratibial injection, and intracardiac (left ventricular) inoculation ...

Challenges of modeling pristane‐induced lupus in non‐human primates

Animal Models and Experimental Medicine, EarlyView.
Systemic lupus erythematosus (SLE) in cynomolgus monkeys was modeled by two intraperitoneal injections of pristane at a dose of 3.5 mL/kg, administered at weeks 1 and 23. Serum samples from all monkeys that received pristane tested positive for antinuclear antibodies.
