术语异染色质已被应用于大规模的，显微镜下可见的染色中心和小规模的，沉默的基因位于染色中心外。这可能会导致对这两种特征的表观遗传标记的解释混淆。模式植物拟南芥（Arabidopsis thaliana）为研究不同组织水平的染色质状态的组成和功能提供了一个很好的系统。在这篇综述中，我们将讨论在拟南芥基因沉默和可见异染色质的关系的分子网络的最新发展。
The term heterochromatin has been applied to both large-scale, microscopically visible chromocentres and small-scale, silent genes located outside chromocentres. This may cause confusion in the interpretation of epigenetic marks for both features. The model plant Arabidopsis thaliana provides an excellent system to investigate composition and function of chromatin states at different levels of organization. In this review we will discuss recent developments in molecular networks underlying gene silencing and the relationship with visible heterochromatin in Arabidopsis.
