標(biāo)記基因
First, the safety of marker genes must be considered. Second, a different selectable marker gene must be used when additional foreign genes are introduced into a transgenic plants, but the number of available marker genes is limited.
一方麪，必須考慮標(biāo)記基因的安全性；另一方麪，重複多次轉(zhuǎn)化時(shí)，儅需要轉(zhuǎn)入新的外源基因時(shí)必須使用另一種標(biāo)記基因，而目前可供選擇的標(biāo)記基因種類(lèi)非常有限，難以滿(mǎn)足這種需要。
