Description
Metal and metalloid stresses present substantial obstacles for plants, exerting an impact on agricultural productivity as well as environmental well-being. The assimilation and accumulation of heavy metals, for example, cadmium and lead, along with metalloids such as arsenic, has the potential to affect the growth and development of plants detrimentally. To address these stresses, innovative biotechnological approaches involving genetic engineering, clustered regularly interspaced short palindromic repeat (CRISPR) technology, phytoremediation, nanobiotechnology, and panomics are required to augment plant-metal tolerance. The dawn of CRISPR technology has revolutionized the field of plant biotechnology with its unparalleled precision in enhancing a plants capability to tolerate heavy metal and metalloid stresses. This present review aims to discuss the various applications and techniques of CRISPR technology in the enhancement of metal stress-tolerant capability in plants. It places special attention on the technologys critical role in abbreviating the detrimental effects of metal stress on plant growth and productivity. CRISPR technology enables researchers to engage in precise gene editing, thereby allowing for the deliberate targeting of specific genes associated with metal transport, detoxification, and stress responses in plants. By manipulating these key genes, CRISPR facilitates the creation of plant varieties that exhibit enhanced resilience to the challenges posed by heavy metal and metalloid stresses. In addition, this approach contributes to the advancement of agricultural sustainability and environmental stewardship by enhancing a plants ability to resist and overcome heavy metals contamination. Moreover, in the face of a changing climate landscape influenced by metal pollution challenges, the precise gene editing capabilities of CRISPR can be harnessed to engineer plants that possess heightened resilience to metal stress, thereby playing a vital role in ensuring food security and promoting sustainable agriculture. The review also underscores the pivotal role of CRISPR technology in shaping the future of research on plant stress tolerance and highlights its immense potential in addressing the evolving challenges associated with metal stress in plant systems. 2025 Elsevier Inc.
