Environment: Plunder of Tanzanian farmers' sorghum through patents
Geneva, 18 Jan (Riaz
K. Tayob) -- A new study questions the legal and ethical basis for patents
granted, and other pending applications, on a gene isolated from a Tanzanian
farmers' variety of sorghum that may yield tremendous profits outside
for multinational corporations and research institutions outside
The December 2009 African Centre for Biosafety briefing paper "Africa's Granary Plundered: Privatisation of Tanzanian Sorghum Protected by the Seed Treaty" by Edward Hammond states that the gene, named SbMATE, has enormous commercial potential because sorghum plants with the gene are tolerant to the negative combination of acid and aluminium commonly found in soils throughout the world.
Even though the research is still in its infancy, large corporations have already expressed interest in licensing SbMATE for further research for application in other species through genetic engineering, possibly in maize, rice and eucalyptus trees.
The briefing paper
questions the ownership of the gene from Tanzanian sorghum (IS7173),
as patented in the
"Not long ago, it seemed like the question was settled in favour of farmers and citizens of developing countries," the briefing paper states.
This was through a 1994 In Trust Agreement between the Consultative Group on International Agricultural Research (CGIAR) and the UN Food and Agriculture Organisation (FAO), and then by the International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA), in which it was established that the vast collection of farmers' germplasm held by the CGIAR could not be patented "in the form received" from those collections.
The rational for the prohibition on intellectual property claims was to further CGIAR's mission, "to achieve sustainable food security and reduce poverty in developing countries through scientific research."
The briefing paper states that the variety of sorghum from which SbMATE is sourced is part of the CGIAR collection and is covered by Annex 1 of the ITPGRFA.
Embrapa, one of
three of the patent applicants, obtained its material from Hugh Doggett

Also claimed are genetically engineered plants of any species that express the Tanzanian tolerance gene. Specifically claimed are wheat, maize, sorghum, and rice plants with the SbMATE gene.
The benefits of the SbMATE gene are not limited to sorghum. For those that promote the widespread use of genetically modified plants, the gene has the potential to unlock new agricultural productivity on aluminium toxic soils that cover a large proportion of the world's arable land, the briefing paper states.
While the gene works in principle, research is in its infancy. Widespread commercial use is years away, particularly in non-sorghum crops into which the gene would have to be genetically engineered.

Chemicals is seeking to license SbMATE to use it in maize and sorghum
In 2009, the entire genome of sorghum was sequenced, well before that of other crops. The rapid development of sorghum genomics is in part due to considerable interest in sorghum as a source of ethanol for bio-fuels.

The briefing paper warns that permitting the SbMATE patent to stand, and for the private sector to profit from it, would signal a new open hunting season on privatisation of the vast collection of farmers' varieties of good crops held by the CGIAR. It cautions that such patent claims pose a grave challenge to the ITPGRFA and CGIAR. +
