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.

Heterochromatin re-organization associated with the transcriptional reprogramming under viral infection in Arabidopsis

This study identifies epigenetic reorganization during viral infection in Arabidopsis, linking it to transcriptional reprogramming and genome stability.

Cloud-controlled microscopy enables remote project-based biology education in Latinx communities in the United States and Latin America

The paper describes a remote-controlled microscopy framework for project-based biology education, showing increased student interest in STEM after participation.

Miniature Structured Illumination Microscope for in vivo 3D Imaging of Brain Structures with Optical Sectioning

The paper introduces a miniature fluorescence microscope for high-resolution 3D brain imaging with optical sectioning, demonstrating its use in fixed and living mouse brain tissue.

Expression dynamics of ARGONAUTE proteins during meiosis in Arabidopsis

The paper investigates the subcellular localization of ARGONAUTE proteins during male meiosis in Arabidopsis, finding distinct nuclear and cytoplasmic distributions correlating with their roles in transcriptional and posttranscriptional gene silencing.

Aphid feeding induces the relaxation of epigenetic control and the associated regulation of the defense response in Arabidopsis

This study shows aphid feeding reduces DNA methylation in Arabidopsis, affecting gene expression and plant defense against aphids.

MicroRNA function transitions from regulating developmental genes to transposable elements during the maturation of pollen

The paper analyzes microRNA dynamics during pollen development, showing a shift from regulating developmental genes to controlling transposable elements in mature pollen.

Functional role of Polymerase IV during pollen development in Capsella

Loss of Polymerase IV function in Capsella rubella causes microspore arrest, revealing an important functional role of Polymerase IV during pollen development.

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.

microRNA-triggered transposon small RNAs mediate genome dosage response

The paper shows that miR845 targets transposon PBS in Arabidopsis pollen, triggering small RNA accumulation that mediates hybridization barriers and endosperm balance.

Paternal easiRNAs regulate parental genome dosage in Arabidopsis

This study identifies paternal easiRNAs as regulators of the triploid block in Arabidopsis, showing they control DNA methylation and seed viability through imprinted gene expression.

tRNA-derived small RNAs target transposable element transcripts

The paper identifies tRNA-derived small RNAs (tRFs) as regulators of genome stability by targeting transposable element transcripts in plants.
