[Mechanism and prevention measures of gene silencing].

With the widely application of transgene technology in the fields of high-level biologies, more and more attention was payed to gene silence. Gene silence can take place at the phase of transcription and post-transcription. With the results of methylation, repeated copies and homologous sequence of inner genes, trans-gene are silenced. There are many kinds of mechanisms of gene silencing and here, the mechanisms explaining the gene silence and some prevention measures were summarized in this paper.
