Globalization: Transgenic Cotton Harbours Hidden Dangers

IPS ipsnews.net: "Wild cotton in Mexico has been contaminated with genetically modified material, posing a risk to biodiversity, experts say. This worrying conclusion was reached by six scientists at the National Autonomous University of Mexico (UNAM) and the National Commission for Knowledge and Use of Biodiversity (CONABIO) in a research study published this month in Molecular Ecology, an international journal.

In their article "Recent long-distance transgene flow into wild populations conforms to historical patterns of gene flow in cotton (Gossypium hirsutum) at its centre of origin", the experts showed that cotton genes and transgenes can be transferred between populations thousands of kilometres apart by seed dispersal. They also found that varieties of Mexican wild cotton that harbour transgenes (genes from one species introduced artificially into another) undergo rapid evolution, with unpredictable consequences." read more
