The TUTase URT1 regulates the transcriptome of seeds and their primary dormancy

Jackson Peter, Jeanne Roignant, Sebastian Sacharowski, Élodie Ubrig, Benjamin Lefèvre, Szymon Świeżewski, Dominique Gagliardi, Hélène Zuber

This study identifies URT1 as the main enzyme for mRNA uridylation in Arabidopsis, showing its role in shaping the seed transcriptome and regulating primary dormancy.

Chromatin crosstalk between HDA19 and NuA4 sets thresholds for stress gene activation in Arabidopsis

Wojciech Dzięgielewski, Anna Bieluszewska, Tomasz Bieluszewski, Michał Krzysztoń, Alexandre Pelé, Maja Szymańska-Lejman, Anna Wilhelm, Szymon Świeżewski, Piotr A. Ziółkowski

This study shows that HDA19 and NuA4 interact to regulate stress gene activation in Arabidopsis by modulating H3K9ac and H2A.Zac, with H3K9ac being the primary driver of transcription.

The UBP5 histone H2A deubiquitinase counteracts PRC2-mediated repression to regulate Arabidopsis development and stress responses

James Godwin, Mohan Govindasamy, Nedounsejian Kiruba, Eduardo March, Ronan Halton, Clara Bourbousse, Léa Wolff, Antoine Fort, Michał Krzysztoń, Jesús López Corrales, Szymon Świeżewski, Fredy Barnèche, Daniel S. P. Schubert, Sara Farrona

This study identifies UBP5 as an interactor of PRC2 in Arabidopsis, showing it regulates development and stress responses by counteracting PRC2-mediated repression through H2Aub erasure.
