Simple Identification of Transgenic Arabidopsis Plants Carrying a Single Copy of the Integrated Gene

抄録

Transgenic Arabidopsis thaliana plants carrying a single copy of integrated DNA can be identified by single-step genomic polymerase chain reaction. The reaction employs two sets of primer pairs with the same melting temperature that amplify the amplicons derived from the integrated T-DNA together with those from an endogenous single-copy gene as a reference. When the band intensity ratio is one, this means that the transgenic plants are carrying a single copy of the integrated gene per haploid.
