Polygalacturonaseassay

This enzyme is famous for being involved in the development of the GMO tomatoes (more information from the link at the foot of this page). The cells of these tomatoes have been genetically modified to contain a reversed copy of the gene for this enzyme. This produces anti-sense mRNA which combines with the normal mRNA for polygalacturonase, effectively supressing its synthesis. As a result the GM tomatoes have o......阅读全文
