近20年来，我国科学家在小麦遗传转化的三个方面取得了重大进展。首先，建立并优化了小麦遗传转化平台，以提高转化效率，缩短从启动转化程序到获得可育转基因小麦植株所需的时间，并克服小麦遗传转化在大范围优良品种中的基因型依赖性问题。第二，借助CRISPR/cas9等新兴技术，研究了100多个小麦基因的功能。最后，将现代技术与杂交等传统育种技术相结合，加快小麦转基因技术的应用。总之，小麦基因工程技术改善了小麦的品质和抗逆性。目前，整合品质改良基因和抗逆基因的转基因小麦已进入田间生产试验阶段。本文对小麦遗传转化的研究现状进行了综述，并对我国小麦遗传转化研究的历史作了简要的总结。
In the past two decades, Chinese scientists have achieved significant progress on three aspects of wheat genetic transformation. First, the wheat transformation platform has been established and optimized to improve the transformation efficiency, shorten the time required from starting of transformation procedure to the fertile transgenic wheat plants obtained as well as to overcome the problem of genotype-dependent for wheat genetic transformation in wide range of wheat elite varieties. Second, with the help of many emerging techniques such as CRISPR/cas9 function of over 100 wheat genes has been investigated. Finally, modern technology has been combined with the traditional breeding technique such as crossing to accelerate the application of wheat transformation. Overall, the wheat end-use quality and the characteristics of wheat stress tolerance have been improved by wheat genetic engineering technique. So far, wheat transgenic lines integrated with quality-improved genes and stress tolerant genes have been on the way of Production Test stage in the field. The debates and the future studies on wheat transformation have been discussed, and the brief summary of Chinese wheat breeding research history has also been provided in this review.
