Tobacco Strain to Clean Up Environmental Toxin

A new strain of tobacco plant can make antibodies to clean up toxic pond scum that affects humans, livestock and wildlife, was suggested by scientists in a new research.

In a new research report appearing in the March 2010 print issue of the FASEB Journal, scientists explain how they developed a genetically modified strain of tobacco that helps temper the damaging effects of toxic pond scum, scientifically known as microcystin-LR (MC-LR), which makes water unsafe for drinking, swimming, or fishing.

This plant could serve as a major tool for helping keep water sources safe to use, especially in developing nations.

"We hope that our study will ultimately lead to a reduction in the exposure of humans, livestock, and wildlife to environmental pollutants," said Pascal M.W. Drake, co-author of the study, from the Centre for Infection at St. George's University of London.

To develop this type of tobacco, Drake and colleagues genetically altered a tobacco plant to produce an antibody to MC-LR, by inserting genes which code for the production of this antibody.

With the genes in place, the new strain of tobacco produced the antibody in its leaves and secreted the antibody from its roots into the surrounding hypotonic growth medium.
