基因编辑技术介导的作物抗除草剂育种研究

Research Advances in CRISPR/Cas9-mediated Breeding of Herbicide-resistant Crops

  • 摘要: 田间杂草威胁农作物正常生长,显著降低作物产量,威胁粮食安全。生产上大量使用化学除草剂严重影响作物产量及生态环境,因此,培育除草剂抗性作物并精准施用化学除草剂,对提高杂草防效尤为重要。基因编辑技术的出现为作物抗除草剂育种提供了快速、有效、安全的新途径。本文阐述了锌指核酸酶(zinc finger nuclease, ZFN)技术、类转录激活因子效应物核酸酶(transcription activator-like effector nuclease, TALEN)技术和基于成簇规律间隔回文重复序列与相关蛋白(clustered regularly interspaced shortpalindromic repeats/CRISPR-associated protein, CRISPR/Cas)系统发展起来的CRISPR/Cas9、碱基编辑、引导编辑技术原理,总结了近年来基因编辑技术在作物抗除草剂育种中的应用,讨论了目前由基因编辑技术介导的抗除草剂育种存在的不足,并对除草剂抗性作物育种未来发展方向做出展望。

     

    Abstract: Spread of weeds hinders the growth and yield of crops in the field. However, application of herbicides to control weed proliferation can ill-affect agricultural productivity as well, and at the same time, harm the environment. Hence, it is crucial for a modern society to resolve the issue and achieve sustainable and eco-friendly farming. Developing herbicide-resistant cultivars with appropriate management is seen as a practical approach. Currently, gene editing offers an effective and safe choice in breeding varieties tolerant to the commonly applied chemicals. This article reviews relevant publications to elucidate the principles of ZFN and TALEN as well as the CRISPR/Cas9 and base and prime editing that evolved from the original CRISPR/Cas system, highlights the applications of gene editing in breeding herbicide-resistant crops, discusses existing deficiencies, and presents the perspective of future development of the science.
