GM virus-resistant potatoes prove fruitful
Researchers have reported successful field trials of genetically modified virus-resistant potatoes in Argentina. They are resistant to potato virus Y, transmitted by insects, Argentine biotechnology association Argenbio reports. Researchers led by Ministry of Science and Technology’s national scientific counsel, the Conicet, scientist Dr Fernando Bravo produced two GM lines and field tested around 2,000 plants across Argentina over a six-year period. They found no virus present in the GM potatoes, while concurrently tested conventional lines showed high infection levels, in some cases of 70-80%. The researchers carried out agronomic tests in non-infected areas, finding the GM lines to be biochemically identical. The findings have been published in Springer-published Transgenic Research.
