摘要：

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