CIL:188^*

Description

The image shows a nucleus isolated from Arabidopsis thaliana immunostained for the HDA6 histone deacetylase (red). DNA is stained blue. HDA6 concentrates in the nucleolus (top center), where ribosomal RNA genes reside.

Technical Details

See K. Earley et al. 2006 Erasure of histone acetylation by Arabidopsis HDA6 mediates large-scale gene silencing in nucleolar dominance. Genes Dev. 20:1283-1293.
