In the pictures above you can see a special transgenic plant. Arabidopsis belongs to the genus and is designed to act as a biosensor. It is produced by a Danish company for a very special purpose.
Normally the plant is green. But if the soil is the NO molecule 2, then the plant changes color. The NO molecule 2 is absorbed by the plant, and once inside, this molecule activates the synthesis of a red pigment.
The Davos Forum held in January 2007 called this pioneering and promising technology. The tests of this plant in Croatia and Serbia were quite successful and are planning to use in Africa. However, there is also criticism. One is that are transgenic plants and be released into the wild. The other is that according to the HALO Trust, is not a good biosensor, for if there is NO release 2, the plant is not dark.
Questions
- What bacteria is used to obtain the transgenic plant? What
- of genes have been introduced for this red pigment?
- Why is using this plant?
