Transformation depends on the expression of numerous bacterial genes whose products appear to be specifically designed to carry out this process.

Virtually the only altered crops the Administration wants to watch more closely are those containing bacterial genes that produce a natural defense against insects.

In it, physicians introduced a bacterial gene that had no effect on the patients' cancer.

As with the mouse, the researchers inserted a bacterial gene that leads to the production of the enzyme.

In both cases, the corn contains a bacterial gene that has not yet been approved for commercial use and is intended to kill rootworms.

It's not been documented previously that bacterial genes got into the human genome.

This meant that all plants without the bacterial gene would die, leading a much higher degree of weed control.

In a test, the company raised crops of genetically engineered tomatoes alongside those lacking the bacterial gene.

The idea of a bacterial gene that turned on a light sounded wonderfully accessible.

He has discovered that several bacterial genes are involved and is now trying to isolate them to see what they do.
