[The new safe strategy on the marker genes in transgenic plant].
The presence in transgenic plants of antibiotic and herbicide resistant selective marker genes might be an unpredictable hazard to the ecosystem as well as to human health. There are two applicable strategies can be used to resolve this problem. One is to remove the resistant marker genes before the transgenic plants are released to field. The other is to develop and use safe marker genes to produce transgenic plants. The present paper reviewed three technique systems employed to remove resistant marker genes in transgenic plants and several safe marker genes used in plant transformation.
