基因沉默与植物抗病毒的可能机制

Plant Transgene Silencing and the Presumable Mechanism of Plant Resistance to Virus

本文根据目前RNA介导的植物病毒抗性(RMVR)、转录后基因沉默(PTGS)的研究成果,从RMVR与PTGS的关系和机制、植物采用基因沉默产生抗性、病毒抑制基因沉默致病及共同进化等几个方面进行介绍了基因沉默可能是植物抵抗病毒的一种机制,深入研究基因沉默不仅在抗病机制上有重要的理论意义,而且对彻底解决植物病毒问题有较大的潜在实用价值。

Based on the present achievements about RNA mediated plant virus resistance and post transcriptional transgene silencing, it is made further discussion in such fields as the relation of RMVR and PTGS and their mechanism, transgene silencing in plants, repressed by virus, and common evolution in paper. It concludes that transgene silencing in plants is probably a mechanism used by plants to resist virus and making further research in transgene silencing is not only important theoretically but also useful potentially in resolving questions on plant virus.
