GH1-HMGA proteins restrict RNA-directed DNA methylation and antagonize linker histone H1 at euchromatic transposable elements

Léa Feit, Alejandro Edera, Emmanuel Vanrobays…·Simon Amiard

The paper shows GH1-HMGA proteins restrict RdDM at euchromatic TEs by limiting siRNA and competing with H1 for chromatin binding.

H3K27me3 and H2A.Z prime cold regulated genes, and their remodelling governs plant cold response

Sarah Mermet, Sarah Muniz Nardeli, Simon Amiard…·Peter Kindgren

The paper investigates how H3K27me3 and H2A.Z chromatin modifications influence cold response in Arabidopsis by analyzing their effects on gene regulation and transcriptional activity.

Replication-independent eviction of H2B.8 reveals chromatin reprogramming during seed imbibition

Lauriane Simon, Stefania Paltrinieri, Manon Verdier…·Aline V. Probst

The paper shows that H2B.8 eviction during seed imbibition initiates replication-independent chromatin reprogramming in Arabidopsis.

Histone H1 protects telomeric repeats from H3K27me3 invasion in Arabidopsis

Gianluca Teano, Lorenzo Concia, Léa Wolff…·Fredy Barnèche

This paper shows that H1 prevents H3K27me3 accumulation at telomeres and ITRs in Arabidopsis by restricting DNA accessibility to TRB proteins, while promoting PRC2 activity at genes.
