“…The latest National Soil Pollution Survey Bulletin reveals that the exceedance rates of cadmium (Cd), nickel (Ni), arsenic (As), copper (Cu), mercury (Hg), and lead (Pb) in China’s cultivated soils were 7.0, 4.8, 2.7, 2.1, 1.6, and 1.5%, respectively . Cadmium, with the highest exceedance rate among these, not only degrades soil functionality and diminishes crop yield and quality but also poses significant health risks through the food chain. , Therefore, developing effective strategies to mitigate Cd accumulation in crops is imperative, and understanding the uptake and translocation processes of Cd in plants is critical to formulating the reduction technologies.…”

Heavy metal contamination in soils poses a significant environmental threat to human health. This study examines the effects of the chiral herbicide napropamide (NAP) on Arabidopsis thaliana, focusing on growth metrics and cadmium (Cd) accumulation. R-NAP does not adversely affect plant growth compared to the control, whereas S-NAP significantly reduces root length and fresh weight. Notably, R-NAP markedly increases Cd accumulation in the shoots, exceeding levels observed in the control and S-NAP. This increase coincides with reduced photosynthetic efficiency. Noninvasive electrode techniques reveal a higher net Cd absorption flux in the root mature zone under R-NAP than S-NAP, although similar to the control. Transcriptomic analysis highlights significant stereoisomer differences in Cd transporters, predominantly under R-NAP treatment. SEM and molecular docking simulations support that R-NAP primarily upregulates transporters such as HMA4. The results suggest careful management of herbicides like R-NAP in contaminated fields to avoid excessive heavy metal buildup in crops.
