Cassava breeds that are resistant to two major viruses could soon be available to farmers in Africa.
Cassava mosaic disease and brown streak disease stunt the growth and rot the roots of crops, respectively.
Mosaic disease alone destroys an estimated 35 million tonnes of African cassava a year — the difference between needing to import food into Africa and achieving food independence, according to researchers at the US-based Donald Danforth Plant Science Center.
The team has shown in the laboratory tests that genetically engineered (GE) tobacco plants resist brown streak disease. Their results will appear in Molecular Plant Pathology next month (August), Claude Fauquet, lead author of the study and director of cassava research at the centre, told SciDev.Net.

The African Union has set up a school to educate and train future regulators in genetically modified (GM) crop biosafety. The African Biosafety Network of Expertise (ABNE) was officially launched in April in Ouagadougou, Burkina Faso, with a five-year, $10.4 million grant from the Bill & Melinda Gates Foundation.

This year, midway through Argentina’s 2005–2015 Strategic Plan for Biotechnology, a long-stalled update of the Seed Law circulating in Buenos Aires may finally reach the legislative floor. The current law, which facilitated the rapid boom of transgenic crops in Argentina in the 1990s—60% of Argentina’s soy crop was genetically modified for herbicide resistance within three years of the introduction of Roundup Ready soy—is a source of conflict over intellectual property rights, as it permits farmers to retain seeds without paying royalties.
However, the meteoric rise in GM crop production was not solely the function of the seed law. Compatible agricultural practices in the early 1990s and a welcoming government contributed. Critics and fans alike say it’s a model from which other developing countries can learn important lessons. Continue reading How green biotech turned white and blue→
A fully equipped laboratory for studying pathogen-resistant transgenic plants will close its doors by the year’s end. The International Centre for Genetic Engineering and Biotechnology (ICGEB) Biosafety Outstation in Ca’Tron di Roncade, Treviso, Italy, was set up to study potential risks concerning genetically modified crops and plant pathogens of importance to the developing world. The outstation’s facilities, part of the ICGEB, were refurbished with financing from Treviso-based Cassamarca Foundation, supported by banking group Unicredit. But the bank’s financial woes have prevented the foundation from renewing the €4-million ($5.7 million), 5-year contract, says Mark Tepfer, leader of the outstation’s Plant Virology group.
