Abstract:

With the development of genome sequencing, molecular biology and transgenic techniques, the number of transgenic plants

authorized for release was increased rapidly. Genetic elements involved in transgenic plants, including selectable markers,

target genes and regulatory genes belongs to three categories (44 genes in total) were summarized in this paper. Plant

species and transgenic events authorized for release by US and European Union, genetically modified materials approved for

import by the Ministry of Agriculture of China were also summarized. The progress for the qualitative and quantitative

detection techniques, including PCR, microarray and combined techniques were discussed in the paper. The development of

transgenic plants and their detection technigues were summarized and outlooked at the end.

Key words: genetic modified organisms, foreign DNA, genetic marker, PCR
