“…Significantly higher expressions of Cd transporters were found in the high Cd accumulation cultivar rather than Cd-PSCs in lettuces . PDR8 (ABC transporter) was upregulated in low-Cd-accumulating pakchoi, while YSL1 was more increased in high-Cd-accumulating phenotype .…”

“…The Cd binding capacity of lignin from Cd-PSCs was influenced by the side chain region composition of Brassica chinensis L. The higher Cd distribution in the cell walls of Cd-PSCs is also supported by transcriptomic evidence as well. The expressions of genes involved in lignin and cellulase biosynthesis were higher induced in Cd-PSCs compared to high Cd-accumulation cultivars in lettuce . Cellulose biosynthesis and pectin de-esterification were enhanced in low-Cd-accumulating Brassica parachinensis L., reducing Cd accumulation in shoots by sequestrating Cd into root cell walls .…”

Cadmium (Cd) contamination in edible agricultural products, especially in crops intended for consumption, has raised worldwide concerns regarding food safety. Breeding of Cd pollution-safe cultivars (Cd-PSCs) is an effective solution to preventing the entry of Cd into the food chain from contaminated agricultural soil. Molecular-assisted breeding methods, based on molecular mechanisms for cultivar-dependent Cd accumulation and bioinformatic tools, have been developed to accelerate and facilitate the breeding of Cd-PSCs. This review summarizes the recent progress in the research of the low Cd accumulation traits of Cd-PSCs in different crops. Furthermore, the application of molecular-assisted breeding methods, including transgenic approaches, genome editing, marker-assisted selection, whole genome-wide association analysis, and transcriptome, has been highlighted to outline the breeding of Cd-PSCs by identifying critical genes and molecular biomarkers. This review provides a comprehensive overview of the development of Cd-PSCs and the potential future for breeding Cd-PSC using modern molecular technologies.
