  1. The mechanisms of gene silencing include copy numbers and configuration of transgene, integration sites in plant and transcription of transgene, etc

    的機制是多方面的,包括轉的拷貝數和構型、在植物上的整合點、轉的轉錄水平
  2. Chloroplast genetic engineering, a new technology that could overcome many problems associated with nuclear genetic engineering, is of growing interest for bioproduction of valuable materials. it has several advantages including the extraordinarily high level of transgene expression and environmental safety, the favorable environment for prokaryote gene expression, the absence of " position effect " and gene silencing

    葉綠體工程是隨著植物遺傳轉化技術發展剛剛興起的生物技術,具有超量表達外源,為原核提供適宜表達環境,消除「置效應」和,環境安全性好優點,較更適合用於植物生物反應器方面的研究。
  3. Though the technique of nuclejc transformation in plants has been developed and used widely, some problems in genetic information have not been resolved. for example, because the nucleic genome is so big and complicated that the integration sites and copies of foreign gene can not be controlled accurately, the expression of transferred genes is inefficient as a result of gene silencing or position effect. in nucleic transformation, furthermore, the transfer of multigene is difficult, and only after the prokaryotic genes undergo modification are they expressed in high plants

    植物的細胞核轉化技術已發展成熟並得到廣泛應用,但核組的遺傳轉化仍存在一系列至今尚未解決的問題:例如由於核組大,背景復雜,外源的整合點和整合的拷貝數難以人為控制,造成鄭州大學2003年博士學論文杜氏鹽藻( dunaliellasalina )葉綠體轉化研究外源表達效率低,容易出現失活、置效應現象;同時轉入多個時操作步驟過于復雜,所表達的原核必須經過修飾改造,環境安全難以保證
