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

Wojciech Dzięgielewski, Anna Bieluszewska, Tomasz Bieluszewski…·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.

Modifying meiotic recombination by targeting chromatin modifiers to crossover hotspots in Arabidopsis

Wojciech Dzięgielewski, Maja Szymańska-Lejman, Anna Wilhelm…·Piotr A. Ziółkowski

The paper demonstrates that targeting H3K4me3 levels via chromatin modifiers affects crossover frequency and transcription at specific genomic loci in Arabidopsis.
