摘要

气候条件的变化增加了非生物胁迫造成严重后果的频率。无论是通过传统育种、基因工程还是其他创新方法,了解非生物胁迫的生理反应对于制定提高植物抗胁迫能力的行动计划至关重要。植物基因编辑是一个快速发展的领域,它涉及有针对性地修改植物基因组,以获得特定的性状或特征。植物最广泛使用的基因编辑技术之一是聚类正则间隔短联合重复序列和 CRISPR 相关蛋白 9(CRISPR-Cas9)。CRISPR-Cas9 可以通过引入靶向突变来精确改变植物的 DNA。应对这些挑战的努力包括通过育种、基因工程和基因编辑开发抗逆植物品种。这些方法旨在提高植物抵御非生物胁迫和从胁迫中恢复的能力,最终提高作物在挑战性环境中的抗逆性、质量和产量。此外,还可以采用可持续农业实践和精准农业技术来优化资源利用,减轻非生物胁迫对作物生产的影响。

Gene Editing: Paving the Way for Enhancing Plant Tolerance to Abiotic Stresses-Mechanisms, Breakthroughs, and Future Prospects

Changes in climatic conditions increase the frequency of severity caused by abiotic stress. Understanding the physiological responses to abiotic stress is crucial for developing action plans to increase stress tolerance in plants, whether through classical breeding, genetic engineering, or other innovative approaches. Gene editing in plants is a quickly advancing field that involves the targeted modification of plant genomes to achieve specific traits or characteristics. One of the plants’ most extensively used gene-editing technologies is Clustered Regularly Interspaced Short Palindromic Repeats and CRISPR-associated protein 9 (CRISPR-Cas9). CRISPR-Cas9 allows making precise changes to the DNA of plants by introducing targeted mutations. Efforts to address these challenges involve the development of stress-tolerant plant varieties through breeding, genetic engineering, and gene editing. These approaches aim to increase the ability of plants to withstand and recover from abiotic stress, ultimately improving crop resilience, quality, and yield in challenging environments. Additionally, sustainable agricultural practices and precision farming techniques can be employed to optimize resource use and mitigate the impact of abiotic stresses on crop production.

期刊介绍: The Journal of Plant Growth Regulation is an international publication featuring original articles on all aspects of plant growth and development. We welcome manuscripts reporting question-based research on various aspects of plant growth and development using hormonal, physiological, environmental, genetic, biophysical, developmental and/or molecular approaches. The journal also publishes timely reviews on highly relevant areas and/or studies in plant growth and development, including interdisciplinary work with an emphasis on plant growth, plant hormones and plant pathology or abiotic stress. In addition, the journal features occasional thematic issues with special guest editors, as well as brief communications describing novel techniques and meeting reports. The journal is unlikely to accept manuscripts that are purely descriptive in nature or reports work with simple tissue culture without attempting to investigate the underlying mechanisms of plant growth regulation, those that focus exclusively on microbial communities, or deal with the (elicitation by plant hormones of) synthesis of secondary metabolites.
