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.
一方面，必须考虑标记基因的安全性；另一方面，重复多次转化时，当需要转入新的外源基因时必须使用另一种标记基因，而目前可供选择的标记基因种类非常有限，难以满足这种需要。
