PDS5s control the Arabidopsis 3D genome by suppressing the formation of TAD-like domains
One key structural element in the three-dimensional (3D) chromatin organization is the Topologically Associating Domain (TAD), which facilitates the formation of distinct chromatin compartments and fosters specific chromatin interactions. Similar chromatin compartments, known as TAD-like domains, have been identified in many plant species. However, the model plant Arabidopsis thaliana has been an exception. In this study, we address this long-standing issue by presenting evidence that Arabidopsis PDS5 proteins play a crucial role in preventing the formation of TAD-like domains.
