Genetic barcodes for ash (Fraxinus) species and generation of new wide hybrids

This paper develops a genetic barcode system for ash species and generates wide hybrids to transfer resistance traits against pests and pathogens.

Kinetochore and ionomic adaptation to whole genome duplication

This study identifies genetic adaptations to whole genome duplication in Cochlearia species, highlighting kinetochore and ion transport gene changes across multiple WGD events.

The phenuivirus Toscana virus makes an atypical use of vacuolar acidity to enter host cells

This study identifies Toscana virus as a late-penetrating virus that uses vacuolar acidity for entry, with an optimal fusion pH of 5.5 and infectious particles remaining viable below this threshold.

Crosstalk between Rac and Rho GTPase activity mediated by Arhgef11 and Arhgef12 coordinates cell protrusion-retraction cycles.

The paper investigates Rac and Rho GTPase crosstalk mediated by Arhgef11 and Arhgef12, showing they coordinate cell protrusion-retraction cycles during migration.

Imaging erythrocyte sedimentation in whole blood

The paper uses optical imaging techniques to study erythrocyte sedimentation structures, finding dynamic channeling gel formations with varying detail resolution across methods.

Host Cell Proteases Drive Early or Late SARS-CoV-2 Penetration

This study investigates how SARS-CoV-2 uses different host cell proteases for entry, showing that TMPRSS2 enables rapid entry while cathepsin L and low pH are required in its absence.

Unequivocal mapping of molecular ether lipid species by LC-MS/MS in plasmalogen-deficient mice

The paper develops an LC-MS/MS method to distinguish plasmanyl and plasmenyl ether lipids in a plasmalogen-deficient mouse model, showing accumulation of plasmanyl species.

Convergence and novelty in adaptation to whole genome duplication in three independent polyploids

The paper investigates adaptation to whole genome duplication in three polyploid species, finding flexible gene recruitment and varying convergence in adaptive processes.

Fatty Acyl Availability Modulates Cardiolipin Composition and Alters Mitochondrial Function in HeLa Cells

This study shows that lipid composition in the growth medium affects mitochondrial cardiolipin composition and respiratory complex I activity in HeLa cells.

Interspecific introgression mediates adaptation to whole genome duplication

The paper shows bidirectional gene flow between Arabidopsis species mediated adaptation to whole genome duplication, rescuing tetraploids from extinction and enhancing meiotic stability.

Projected climate change will reduce habitat suitability for bumble bees in the Pacific Northwest

This study identifies bumble bee species most vulnerable to climate change in the Pacific Northwest using species distribution models and field surveys.

Pervasive population genomic consequences of genome duplication in Arabidopsis arenosa

This study investigates the population genomic effects of polyploidy in Arabidopsis arenosa, finding subtle yet widespread impacts on evolutionary processes.

The first genetic linkage map for Fraxinus pennsylvanica and syntenic relationships with four related species

This paper constructs the first genetic linkage map for green ash and identifies syntenic relationships with four related species.
