We are witnessing the timely convergence of several technologies that together will have significant impact on research, human health and in animal and plant breeding. The exponential increase in genome and expressed sequence data, the ability to compile, analyze and mine these data via sophisticated bioinformatics procedures on high-powered computers, and developments in various molecular and in-vitro cellular techniques combine to underpin novel developments in research and commercial biotechnology. Arguably the most important of these is genome editing which encompasses a suite of site directed nucleases (SDN) that can be designed to cut, or otherwise modify predetermined DNA sequences in the genome and result in targeted insertions, deletions, or other changes for genetic improvement. It is a powerful and adaptive technology for animal and plant science, with huge relevance for plant and animal breeding. But this promise will be realized only if the regulatory oversite is proportionate to the potential hazards and has broad support from consumers, researchers and commercial interests. Despite significant progress in research and development and one genome edited crop close to commercialization, in most regions of the world it still remains unclear how or whether this fledgling technology will be regulated. The various risk management authorities and biotechnology regulators have a unique opportunity to set up a logical, appropriate and workable regulatory framework for gene editing that, unlike the situation for GMOs, would have broad support from stakeholders.
我们正见证着几项技术的及时融合,这些技术结合在一起将对研究、人类健康以及动植物育种产生重大影响。基因组和表达序列数据呈指数级增长,通过高性能计算机上的复杂生物信息学程序来编译、分析和挖掘这些数据的能力,以及各种分子和体外细胞技术的发展,共同为研究和商业生物技术的新发展提供了支撑。可以说,其中最重要的是基因组编辑,它包含了一套可以设计用于切割或修改基因组中预定 DNA 序列的靶向核酸酶(SDN),从而导致靶向插入、缺失或其他遗传改良的变化。这是一种用于动植物科学的强大且适应性强的技术,与动植物育种有巨大的关联。但是,只有当监管监督与潜在危险成比例,并得到消费者、研究人员和商业利益的广泛支持时,这一承诺才会实现。尽管在研究和开发方面取得了重大进展,并且有一个接近商业化的基因组编辑作物,但在世界上大多数地区,人们仍然不清楚如何或是否将对这项新兴技术进行监管。各种风险管理机构和生物技术监管机构都有机会为基因编辑建立一个逻辑合理、适当且可行的监管框架,与转基因生物(GMOs)的情况不同,该框架将得到利益相关者的广泛支持。
