HSFA1a modulates plant heat stress responses and alters the 3D chromatin organization of enhancer-promoter interactions

Here the authors show genome-wide chromatin changes and transcriptional reprogramming occur in response to heat stress in tomato, leading to the transient formation of promoter-enhancer contacts to drive the expression of heat-stress responsive genes. Furthermore, they show chromatin spatial reorganization requires HSFA1a, a transcription factor (TF) essential for heat stress tolerance in tomato.
