Cadmium (Cd) contamination in soils and accumulation in cereal grains have posed food security risks and serious health concerns worldwide. Understanding the Cd transport process and its management for minimizing Cd accumulation in cereals may help to improve crop growth and grain quality. In this review, we summarize Cd uptake, translocation, and accumulation mechanisms in cereal crops and discuss efficient measures to reduce Cd uptake as well as potential remediation strategies, including the applications of plant growth regulators, microbes, nanoparticles, and cropping systems and developing low-Cd grain cultivars by CRISPR/Cas9. In addition, miRNAs modulate Cd translocation, and accumulation in crops through the regulation of their target genes was revealed. Combined use of multiple remediation methods may successfully decrease Cd concentrations in cereals. The findings in this review provide some insights into innovative and applicable approaches for reducing Cd accumulation in cereal grains and sustainable management of Cd-contaminated paddy fields.

谷类作物中的镉：吸收和运输机制及最小化策略

土壤中的镉 (Cd) 污染和谷物中的积累已在全球范围内构成粮食安全风险和严重的健康问题。了解 Cd 运输过程及其管理以最大限度地减少谷物中 Cd 的积累可能有助于改善作物生长和谷物质量。在这篇综述中，我们总结了谷类作物对镉的吸收、转运和积累机制，并讨论了减少镉吸收的有效措施以及潜在的修复策略，包括植物生长调节剂、微生物、纳米颗粒和种植系统的应用以及开发低- CRISPR/Cas9 的 Cd 谷物栽培品种。此外，还揭示了 miRNA 调节 Cd 易位，并通过调控其靶基因在作物中积累。多种修复方法的联合使用可能会成功降低谷物中的镉浓度。本综述的研究结果为减少谷物中 Cd 积累和 Cd 污染稻田可持续管理的创新和适用方法提供了一些见解。
