PDS5A modulates cohesin loop extrusion in Arabidopsis thaliana, shaping TAD-like chromatin architecture with highly similar domain patterns across tissues and ploidy levels.
- Why it matters: Plant 3D genome folding and how cohesin regulation controls TAD-like structures is unresolved, limiting understanding of how chromatin architecture supports gene regulation.
- What they did: Using Hi-C and Micro-C, the study tested pds5a genetics and biochemical interactions, showing TAD-like domains depend on SYN4 and are opposed by WAPL1/2, with PDS5A acting as the major unloading factor.
- The result: Micro-C mapped accessible, highly transcribed promoters as loop and stripe anchors, and disrupting distal anchors showed newly formed contacts in pds5a can function as cis-regulatory modules affecting target gene expression.
