Abstract

Transgenic crops were first commercialised almost 20 years ago, which makes it a good opportunity to reflect on this technology. In this review, we compare its status with the predictions included in Vasil's forecast published in 2002. Our analysis shows that science has provided a wide range of possibilities to modify different traits in plants, yet the economy benefits from that range to very different extents. We also point out the most important constituents of the technology development involving methodology improvement and novel traits expressed in varieties introduced into agriculture. Using native genes (or their elements) in transgenes, accumulating previously produced transgenes to cascade resistance and using herbicide resistance as a selectable marker have been considered typical of novel genetically modified (GM) plant varieties. A vast portion of the novelties in stacked varieties is doubtful in terms of EU regulations. Attention has also been directed to completely novel methodology solutions that hold out the prospect of a more comprehensive use of genetic modification in agriculture as a whole, and, particularly, make its use possible in the EU and even in sustainable agriculture.

摘要

转基因作物大约在20年前首次商业化,这使其成为反思这项技术的好时机。在本综述中,我们将其现状与2002年发表的瓦西尔预测中的内容进行了比较。我们的分析表明,科学已经为改变植物的不同性状提供了广泛的可能性,但经济从这些可能性中获得的收益程度却大不相同。我们还指出了技术发展的最重要组成部分,包括方法改进以及引入农业的品种中所表达的新性状。在转基因中使用天然基因(或其元件)、积累先前产生的转基因以实现级联抗性以及使用除草剂抗性作为选择标记已被视为新型转基因植物品种的典型特征。就欧盟法规而言,堆叠品种中的大部分新奇之处都值得怀疑。人们还将注意力转向了全新的方法解决方案,这些方案有望在整个农业中更全面地利用基因改造,特别是使其在欧盟乃至可持续农业中得以应用。
