The repressive role of Arabidopsis H2A.Z in transcriptional regulation depends on AtBMI1 activity

Abstract

Arabidopsis H2A.Z plays an important role in regulating gene expression in response to stressors; however, the underlying mechanism is still puzzling. Here, the authors show that monoubiquitination of H2A.Z by AtBMI1 is required for H2A.Z-mediated transcriptional repression.
