The susceptibility of crop plants towards abiotic stresses is highly threatening to assure global food security as it results in almost 50% annual yield loss. To address this issue, several strategies like plant breeding and genetic engineering have been used by researchers from time to time. However, these approaches are not sufficient to ensure stress resilience due to the complexity associated with the inheritance of abiotic stress adaptive traits. Thus, researchers were prompted to develop novel techniques with high precision that can address the challenges connected to the previous strategies. Genome editing is the latest approach that is in the limelight for improving the stress tolerance of plants. It has revolutionized crop research due to its versatility and precision. The present review is an update on the different genome editing tools used for crop improvement so far and the various challenges associated with them. It also highlights the emerging potential of genome editing for developing abiotic stress-resilient crops.
农作物对非生物胁迫的敏感性对确保全球粮食安全构成了严重威胁，因为这导致每年近50%的产量损失。为了解决这个问题，研究人员不时采用植物育种和基因工程等多种策略。然而，由于与非生物胁迫适应性性状遗传相关的复杂性，这些方法不足以确保胁迫恢复力。因此，研究人员被促使开发具有高精度的新技术，以应对与先前策略相关的挑战。基因组编辑是最新的方法，因其在提高植物胁迫耐受性方面备受关注。由于其多功能性和精确性，它彻底改变了作物研究。本综述是对迄今为止用于作物改良的不同基因组编辑工具以及与之相关的各种挑战的最新介绍。它还强调了基因组编辑在培育非生物胁迫耐受性作物方面的新兴潜力。
