Hop stunt viroid infection alters host heterochromatin

This study investigates how HSVd viroid infection affects heterochromatin in Cucumis sativus by analyzing changes in H3K9me2 and H3K27me3 epigenetic marks and their transcriptional targets.

IL-33 priming and antigenic stimulation synergistically promote the transcription of proinflammatory cytokine and chemokine genes in human skin mast cells

Minimal RNA replicons for targeted gene silencing based on an asymptomatic viroid

The paper develops a gene silencing method using viroids to target specific genes in eggplant, demonstrating systemic spread and effective silencing.

Multiomic analisys reveals that viroid infection induces a temporal reprograming of plant-defence mechanisms at multiple regulatory levels

This study uses multiomic analysis to show that viroid infection causes a time-dependent reprogramming of plant defense mechanisms across multiple regulatory layers.

Diverse pathogens activate the host RIDD pathway to subvert BLOS1-directed immune defense

This study shows that pathogens like Brucella and coronavirus MHV exploit the RIDD pathway to degrade BLOS1, impairing lysosomal trafficking and enhancing their intracellular survival.

Exploring the miRNA-mediated response to combined stresses in melon plants

This study identifies miRNA families responding to combined stresses in melon plants and shows that their response is often non-additive compared to individual stresses.

Enhanced RhoA signaling stabilizes E-cadherin in migrating epithelial monolayers.

The paper shows that RhoA signaling at adherens junctions stabilizes E-cadherin during epithelial migration by increasing junctional contractility and mechanical tension.

A unified view of neighbour cell engagement during apoptotic cell extrusion.

This study identifies RhoA activation via a Myosin VI-dependent mechanotransduction pathway as the mechanism by which apoptotic cells engage neighboring cells for extrusion, with S1P providing priming.

Zygomorphic flowers have fewer potential pollinator species

The paper evaluates pollinator diversity in zygomorphic versus actinomorphic flowers and finds zygomorphic flowers are visited by fewer pollinator species.

A tractable Drosophila cell system enables rapid identification of Acinetobacter baumannii host factors

This study uses Drosophila S2 cells to identify host factors and mechanisms involved in Acinetobacter baumannii intracellular survival and persistence.

Viral fitness determines the magnitude of transcriptomic and epigenomic reprogramming of defense responses in plants

The paper investigates how viral adaptation affects transcriptomic and epigenomic changes in Arabidopsis thaliana during antiviral responses, finding that DNA methylation and histone modifications play a role in defense.

Lokiarchaeon exhibits homoacetogenesis

This paper shows Lokiarchaeon exhibits homoacetogenesis by coupling fermentative H2 production with the Wood-Ljungdahl pathway under anoxic conditions.

Dynamic architecture and regulatory implications of the miRNA network underlying the response to stress in melon

The paper analyzes stress-responsive miRNAs in melon using sRNA sequencing and degradome data, identifying 14 miRNAs and showing conserved miRNA network architecture across crops.

Are tropical reptiles really declining? A six-year survey of snakes in Drake Bay, Costa Rica, and the role of temperature, rain and light

The paper surveys snake populations in Drake Bay, Costa Rica, over six years and finds a decline in numbers, with some species affected more than others, while environmental factors like temperature, rain, and light influence snake activity.
