transposon silencing

Distant hybridization of plants can cause a wide range of apparent genetic variability, such as: gene silencing, nucleolar dominance, transposon activation, DNA methylation variations and so on, and DNA methylation, in particular cytosine methylation is one of the main epigenetic control mechanisms.

植物远缘杂交可以引起广泛的表观遗传变异，如：基因沉默、核仁显性、转座子激活、DNA甲基化变异等，而DNA甲基化尤其是胞嘧啶甲基化是表观遗传的主要调控机制之一。

CHH methylation of small transposable elements is increased in embryos, suggesting that endosperm demethylation enhances transposon silencing.

胚中小的转座元件CHH甲基化作用发生了增强，表明了胚乳的去甲基化增强了转座元件的沉默。

Our results from co-immunoprecipitation experiments, ChIP assays and genetic studies suggest that hnRNP A2/ B1 could bind to selective retrotransposons and recruit HP1 for transposon silencing.

以上免疫共沉淀实验、ChIP检测和基因研究结果表明，hnRNP A2/B1可以选择性结合反转录转座子并且募集具有沉默转座子功能的HP1。
