The dual trxG/PcG protein ULTRAPETALA1 modulates H3K27me3 and directly enhances POLYCOMB REPRESSIVE COMPLEX 2 activity for fine-tuned reproductive transitions

Vangeli Geshkovski, Julia Engelhorn, Jean-Baptiste Izquierdo, Hamida Laroussi, Caroline Thouly, Laura Turchi, Meredith Wouters, Marie Le Masson, Emmanuel Thévenon, Ambre Petitalot, Lauriane Simon, Manon Verdier, Sophie Desset, Philipp Michl-Holzinger, Astrid Bruckmann, , Cristel C. Carles

This study shows ULTRAPETALA1 modulates PRC2 activity and enhances H3K27me3 deposition in Arabidopsis, revealing a bivalent trxG/PcG factor mechanism for chromatin regulation.
