  16. Because there are many copies of chloroplast dna and the chloroplast has a strong tolerance to accumulation of the products expressed by the introduced foreign gene, a high level of expression is often happened in chloroplast transformation. in addition, because of prokaryotic property of the chloroplast, the prokaryotic gene can be expressed in chloroplast without any modification and multigene can be simultaneously transferred in " polycistron ", which is impossible in nucleic transformation

    另外，由於葉綠體基因組的原核性質，對來自原核生物的外源基因無需改造就可以在葉綠體內高效表達，而且可以將多個外源基因採取「多順反子」的原核表達形式同時引入，並由共同的啟動子控制，既方便操作又可避免由於存在多個相同啟動子所帶來的「共沉默」 。
  17. Hdgs induction by progeny containing a low copy number of the vector was also dramatically higher than induction by single copy vectors. the reduction of gfp protein and mrna abundance, and the presence of 21 - 26 nt sirnas could be simultaneously detected in silenced plants and the gfp coding region of these plants was methylated extensively

    在發生沉默的植株體內，在gfp蛋白及其rna被不同程度降解的同時，可以檢測到21 - 26nt的小分子rna （ sirna ） ，同時gfp基因編碼區也受到顯著地甲基化修飾。
