China’s Ministry of Agriculture has decided not to renew biosafety certificates that allowed research groups to grow genetically modified (GM) rice and corn. The permits, to grow two varieties of GM rice and one transgenic corn strain, expired on 17 August. The reasoning behind the move is not clear, and it has raised questions about the future of related research in China.
The ministry, with much fanfare, had approved the GM rice certificates in August 2009. The permits enabled a group at Huazhong Agricultural University in Wuhan to produce two varieties of rice carrying a gene from the Bacillus thuringiensis (Bt) bacteria that provides pest resistance. At the same time, the ministry approved production of a corn strain developed by the Chinese Academy of Agricultural Sciences' Biotechnology Research Institute in Beijing. Researchers had altered the corn so that kernels contain phytase, a livestock feed additive that boosts absorption of phosphorus, which enhances growth. All of the certificates were valid for 5 years.
Since the certificates were issued, however, public skepticism about the benefits of GM crops has grown in China. Some scientists conducting GM plant research have been attacked when giving public lectures.
