提高作物产量以确保粮食安全是一项重大挑战。诱变是作物改良的重要工具，不受对转基因生物的监管限制。正向遗传方法能够鉴定可在常规育种计划中利用的改良或新的表型。强大的反向遗传策略，允许检测诱变群体的个体中诱导的点突变，可以解决将序列信息与基因的生物学功能联系起来的主要挑战，并且还可以识别植物育种的新变异。本文简要讨论了突变体检测的最新进展以及诱变对作物改良的潜力。
Increasing crop yields to ensure food security is a major challenge. Mutagenesis is an important tool in crop improvement and is free of the regulatory restrictions imposed on genetically modified organisms. The forward genetic approach enables the identification of improved or novel phenotypes that can be exploited in conventional breeding programmes. Powerful reverse genetic strategies that allow the detection of induced point mutations in individuals of the mutagenized populations can address the major challenge of linking sequence information to the biological function of genes and can also identify novel variation for plant breeding. This review briefly discusses recent advances in the detection of mutants and the potential of mutagenesis for crop improvement.
