Summary: Large quantities of rice with excessive Cd content are processed every year, but cannot be discarded due to the risk of secondary pollution. To ensure food safety, prevent food waste, and eradicate hunger, the best solution is to use modern physical, chemical, and biological techniques to reduce the Cd content in postharvest Cd-contaminated rice.

Summary: In this study, researchers focused on the ability of plant endophytic bacteria to improve plant responses to various stresses. Bacteria were isolated from the SWAT-1 rice variety and characterized biochemically and morphologically. The study found that these endophytic bacteria can enhance plant growth, increase the uptake of cadmium, and exhibit antimicrobial activity. The findings suggest that these isolates have the potential to be used as biocontrol agents and biofertilizers.

Summary: This study found that knockout of OsNRAMP5 can reduce Cd uptake while facilitating Cd translocation from roots to shoots. Knockout of OsNRAMP5 significantly reduces Cd accumulation in rice shoots and enhances Cd tolerance. Additionally, the OsNRAMP5 mutation promotes the preferential delivery of Mn to young leaves and grains.

Summary: ENPs can resist heavy metal toxicity in plants, but their coexposure still exhibits toxicity to plants. This study aimed to investigate the toxic mechanism of nano TiO2 or TiO2-Cd on rice using transcriptomics and metabolomics. The findings showed that nano TiO2-Cd coexposure significantly decreased the plant height and root dry weight of rice. Nano TiO2 exposure induced regulation of DEGs and metabolites, while nano TiO2-Cd coexposure identified a greater number of DEGs and differential metabolites. The study highlights the importance of being cautious when using ENPs to combat heavy metal phytotoxicity.

Summary: Medicinal plants have various uses worldwide, but their quality is affected by cadmium pollution. Medicinal plants have complex mechanisms to cope with cadmium stress, including antioxidant systems and chelating peptides. While progress has been made in exploring the physiological mechanisms, research into molecular mechanisms is still lacking. This review provides a reference for studying the responses of medicinal plants to cadmium stress.

Summary: Cadmium contamination is a significant problem for both plants and human health in China. Finding a way to cultivate safe and high-yielding rice in Cd-contaminated alkaline soils remains a challenge. Through small-scale and large-scale field experiments, it was concluded that a combination of humic acid, foliar and soil silicate fertilization, and shallow plowing produced the best results in terms of low soil bioavailable Cd, low grain Cd concentrations, and high grain yield. Rice farmers are advised to adopt this combination for high-yield, low Cd rice production in alkaline soils.

Summary: Non-essential toxic heavy metals like cadmium (Cd2+) have adverse effects on the growth and development of plants and can potentially harm human health. This study focused on the role of a peroxidase gene family member, PgGPx, in rice under Cd2+ stress. The overexpression of PgGPx enhanced Cd2+ tolerance in transgenic rice plants and improved oxidative stress response by increasing the activity of antioxidant enzymes. These findings provide insights for developing strategies to engineer Cd2+ stress tolerance in economically important crop plants.

Summary: This study found that the endophytic bacterium MCS15 reduced cadmium toxicity in rice plants by secreting glucuronic acid, which inhibited the synthesis of ethylene and weakened the iron uptake system in rice roots, thereby preventing cadmium accumulation.

Summary: The study investigated the response of Nicotiana benthamiana plants expressing SP/hrpZ(Psph) under cadmium stress. The transgenic plants demonstrated significant differences in germination rates and growth parameters compared to wild-type plants, with some lines showing superior resistance to cadmium stress. Additionally, a tissue-specific cadmium accumulation pattern was observed between wild-type and hrpZ(Psph)-plants, suggesting potential mechanisms underlying the resistance to cadmium stress.

Summary: The large amounts of enriched cadmium in the environment pose serious threats to the aquaculture industry and food processing industry. Studying the toxic effects of cadmium on fish and its possible effects on human health is significant. Research has shown that cadmium accumulation in fish causes tissue differences and damages various physiological systems, including antioxidant defense, reproduction, and immunity.

Summary: Cadmium pollution poses risks to rice production and human health. NH224 exhibits stronger Cd-tolerance ability compared to NH199, with lower Cd translocation factor. Metabolomic analysis reveals that NH224 has more active amino acids biosynthesis, hormone metabolism, lipids-related metabolism, phenylalanine metabolism, and phenylpropanoid biosynthesis pathways, associated with antioxidant defense, cell wall biosynthesis, phytochelatins synthesis, and plasma membrane stability maintenance.
