Abstract

We review the undertaking of a field trial of low asparagine wheat lines in which the asparagine synthetase gene, TaASN2, has been knocked out using CRISPR/Cas9. The field trial was undertaken in 2021-2022 and represented the first field release of genome edited wheat in Europe. The year of the field trial and the period since have seen rapid changes in the regulations covering both the field release and commercialisation of genome edited crops in the UK. These historic developments are reviewed in detail. Free asparagine is the precursor for acrylamide formation during high-temperature cooking and processing of grains, tubers, storage roots, beans and other crop products. Consequently, work on reducing the free asparagine concentration of wheat and other cereal grains, as well as the tubers, beans and storage roots of other crops, is driven by the need for food businesses to comply with current and potential future regulations on acrylamide content of foods. The topic illustrates how strategic and applied crop research is driven by regulations and also needs a supportive regulatory environment in which to thrive.

低天门冬酰胺小麦:在有关食品中丙烯酰胺和作物基因组编辑的法规快速变化的背景下,欧洲首次对基因组编辑小麦进行田间试验。
我们回顾了利用 CRISPR/Cas9 基因敲除天门冬酰胺合成酶基因 TaASN2 的低天门冬酰胺小麦品系的田间试验。田间试验于 2021-2022 年进行,是基因组编辑小麦在欧洲的首次田间发布。在田间试验当年及此后的一段时间里,英国有关基因组编辑作物的田间发布和商业化的法规发生了迅速变化。本文对这些历史性发展进行了详细回顾。游离天冬酰胺是谷物、块茎、贮藏根茎、豆类和其他作物产品在高温烹饪和加工过程中形成丙烯酰胺的前体。因此,降低小麦和其他谷物以及其他作物的块茎、豆类和贮藏根中游离天门冬酰胺浓度的工作,是由食品企业遵守当前和未来可能出台的食品丙烯酰胺含量法规的需要所驱动的。该主题说明了战略性和应用性作物研究如何受到法规的驱动,同时也需要一个支持性的法规环境才能蓬勃发展。
