Molecular features of RNA silencing against phloem-restricted polerovirus TuYV enable amplification of silencing signal from host transcripts

M. Clavel, E. Lechner, M. Incarbone, T. Vincent, V. Cognat, E. Smirnova, M. Lecorbeiller, V. Brault, V. Ziegler-Graff, P. Genschik

The paper investigates RNA silencing against TuYV in Arabidopsis, revealing 22-nt vsiRNA production by DCL2 and AGO1 stabilization despite viral suppression.

Epigenetic silencing of clustered tDNAs in Arabidopsis

G. Hummel, A. Berr, S. Graindorge, V. Cognat, E. Ubrig, D. Pflieger, J. Molinier, L. Drouard

The paper shows that clustered tDNA regions in Arabidopsis are transcriptionally silent due to DNA methylation and repressive chromatin features, contrasting with dispersed tDNAs that have permissive marks.

Photodamage repair pathways contribute to the accurate maintenance of the DNA methylome landscape upon UV exposure

S. Graindorge, V. Cognat, P. Johann to Berens, J. Mutterer, J. Molinier

This study shows that DNA repair pathways prevent methylation changes at UV-damaged sites in plants, highlighting their role in maintaining methylome integrity.
