Curing cassava of deadly virus infections


Date: 17/12/2013


Maruthi Gowda and his team from the Natural Resources Institute of the University of Greenwich have developed a procedure for eliminating virus infections from cassava. They built a 'virus-indexing' procedure for cleaning cassava lines, which involves a combination of protocols for accurate identification and elimination of viruses. The procedure involves growing disease-infected cassava stem cuttings and identifying at a later stage plants free of disease symptoms. Plants free of viruses are then grown in tissue culture media, certified to be virus-free after several disinfection protocols and shipped to African partners for further multiplication and subsequent distribution to farmers.
