Deletion of RNAi components impairs both methylation of histone H3K9 and heterochromatization. This suggests that RNAi plays a role in heterochromatization by regulating histone modifications. When the RNAi pathway is disrupted, H3K9 methylation and heterochromatization are also affected, indicating that RNAi is involved in maintaining proper chromatin structure.
