A bacterial effector directly targets Arabidopsis Argonaute 1 to suppress Pattern-triggered immunity and cause disease

This study shows that the bacterial effector HopT1-1 targets Arabidopsis AGO1 to suppress miRNA function and PTI, leading to disease.

Cell type-specific control of secondary cell wall formation by Musashi-type translational regulators in Arabidopsis

This study identifies MSIL2 and MSIL4 as cell type-specific regulators of secondary cell wall formation in Arabidopsis by controlling mRNA translation and biosynthetic gene expression.

Adaptive duplication and functional diversification of Protein kinase R contribute to the uniqueness of bat-virus interactions

This study shows that bat PKR genes have evolved through duplication and functional diversification, enabling unique antiviral defenses against DNA and RNA viruses.

Species-specific molecular barriers to SARS-CoV-2 replication in bat cells

The paper investigates SARS-CoV-2 replication in bat cells and finds species-specific molecular barriers, with some cells controlling viral replication after human ACE2 expression.

A plant-like mechanism coupling m6A reading to polyadenylation safeguards transcriptome integrity and developmental genes partitioning in Toxoplasma

This paper identifies an m6A-dependent polyadenylation mechanism in Toxoplasma gondii that prevents transcriptional read-through and maintains transcriptome integrity, similar to a plant mechanism.

Rapid evolution of mammalian HERC6 and independent duplication of a chimeric HERC5/6 gene in rodents and bats suggest an overlooked role of HERCs in antiviral innate immunity

This study identifies rapid evolutionary changes in HERC5 and HERC6 genes across mammals, revealing adaptive evolution in HERC6 and a chimeric HERC5/6 gene in rodents and bats, suggesting roles in antiviral immunity.

eDNA metabarcoding reveals a core and secondary diets of the greater horseshoe bat with strong spatio-temporal plasticity

This study uses eDNA metabarcoding to analyze the diet of greater horseshoe bats, revealing a core and secondary diet with strong spatio-temporal variation.

Integrating population genetics to define conservation units from the core to the edge of Rhinolophus ferrumequinum western range

This study uses microsatellite markers to analyze genetic diversity and structure in Rhinolophus ferrumequinum populations across Western Europe, identifying barriers to dispersal and suggesting management units.

Bacterial transformation buffers environmental fluctuations through the reversible integration of mobile genetic elements

This study shows that bacterial transformation optimizes fitness in fluctuating environments by reversibly integrating beneficial mobile genetic elements.

Metabarcoding for the parallel identification of several hundred predators and their preys: application to bat species diet analysis

This paper develops a metabarcoding approach to identify bat species and their arthropod prey from fecal samples, improving taxonomic resolution and reducing false positives through controls and replicates.
