Against the neoliberal steamroller? The Biosafety Protocol and the social regulation of agricultural biotechnologies 总被引:1,自引:0,他引:1
Through a discursive and organizational analysis we seek to understand the Biosafety Protocol and the place of socioeconomic
regulation of agricultural biotechnology in it. The literature on the Protocol has been fairly extensive, but little of it
has explored debates over socioeconomic regulation during the negotiation process or the regulatory requirements specified
in the final document. This case is especially important at a time when the spread of neoliberalism is increasingly associated
with deregulation, because it sheds light on the conditions under which circumvention of the market is deemed legitimate and
socio-economic regulation of agricultural technology is possible.

There is a fundamental divergence of opinion between the EU and the US over how food products derived from genetically modified organisms should be labeled. This has less to do with safety, as moves towards the international harmonization of safety standards continue apace, and rather more to do with the consumers' right to know about the origins of the food they are consuming. This paper uses a framework drawn from the global public goods (GPG) literature of economics and the work by international relations theorists on formal international organizations (FIO) to explain why there is presently no global consensus on the manner (voluntary or mandatory) in which GM food products should be labeled. 相似文献

[目的]构建适用于转基因大豆MON89788检测的质粒标准分子.[方法]利用定性PCR和连接、转化等分子克隆技术,将大豆内标准基因lectin、MON89788的3'端特异性序列和5'端特异性序列依次克隆到pMD18-T载体上,获得质粒标准分子pMD-LM3M5,并进行适用性验证.[结果]获得了3 700 bp的质粒标准分子,其中重组DNA片段1 029 bp.该质粒标准分子的定性PCR检测灵敏度达到10 copy.[结论]该研究构建的质粒标准分子pMD-LM3M5能替代NON89788基体标准品,用于MON89788大豆及其产品的定性PCR检测.
Abstract:
[Objective] The aim was to construct a plasmid reference molecule (PRM) for detection of transgenic soybean MON89788.[Method]the lectin gene sequence,3'-junction and 5'-junction sequence between host plant DNA integrated DNA of MON89788 soybean were amplified independently,and the three fragments were cloned into the cloning vector pMD18-T in order through molecular manipulation method to construct pMD-LM3M5,the applicability of the constructed novel PRM was tested. [Result] Sequencing confirmation result showed that the PRM was 3 700 bp in length,containing 1 029 bp of recombined DNA fragment.The limits of qualitative detection of the PRM were 10 copies,[Conclusion]The PRM constructed in this study was suitable for the identification of MON89788 event. 相似文献
