Genetically Engineered Tobacco Keeps Water Clean

Monday, March 1, 2010 - 12:28 in Biology & Nature

Scientists writing in the FASEB Journal say a genetically modified strain of tobacco can help temper the damaging effects of toxic pond scum, known as microcystin-LR (MC-LR), which makes water unsafe for drinking, swimming, or fishing. The plant could serve as a major tool for helping keep water sources safe to use, especially in developing nations. The new strain was developed by inserting genes which code for the production of an antibody called MC-LR. With the genes in place, the new strain of tobacco produced the antibody in its leaves and secreted it from its roots into the surrounding hypotonic growth medium. read more
