  2. 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

    的細胞核轉化技術已發展成熟並得到廣泛應用,但核基因組的轉化仍存在一系列至今尚未解決的問題:例如由於核基因組大,背景復雜,外源基因的整合位點和整合的拷貝數難以人為控制,造成鄭州大學2003年博士學位論文杜氏鹽藻( dunaliellasalina )葉綠體轉化研究外源基因表達效率低,容易出現基因失活、基因沉默、位置效應等現象;同時轉入多個基因時步驟過于復雜,所表達的原核基因必須經過修飾改造,環境安全難以保證等。
