For decades, a major goal of scientists working in agricultural biotechnology has been to design transgenic plants with low transgene copy numbers and no T-DNA vector backbone integration. T-DNA vector backbones usually harbor bacterial antibiotic resistance genes, leading to a variety of regulatory issues. Also, plants with high transgene copy numbers will often silence the expression of important genes. Current methods generate a large number of transgenic plants, subject them to a variety of tests, and then discard those with multiple transgenes and vector backbone sequences. These methods are both time consuming and expensive.

Researchers at Purdue University have developed a system to generate transgenic plants with low transgene copy numbers and have almost eliminated the presence of T-DNA binary backbone sequences in these plants. This system will be very useful for the transformation of plants and offers improved quality of transformed plants, without regulatory issues or inhibiting gene expression.
