Summary: Heavy metal contamination in soil and water is a global issue, posing health risks to plants, animals, and humans. Plants have evolved mechanisms to cope with heavy metal toxicity, including vacuolar sequestration. Manipulation of genes involved in vacuolar sequestration pathways has led to the development of transgenic plants for phytoremediation and food safety applications.

Summary: In this review, the beneficial effects of arsenic (As) in P. vittata, including growth promotion, elemental defense, and other potential benefits, are highlighted. The mechanisms of As coping in P. vittata, such as uptake, reduction, efflux, translocation, and sequestration/detoxification, are also discussed. It is hypothesized that P. vittata has evolved strong capacities for As uptake and translocation to obtain beneficial effects, leading to the accumulation of high As concentrations.

Summary: There are two ATP-dependent proton pumps in plant cells, the Plasma membrane H+-ATPase (PM H+-ATPase) and the vacuolar H+-ATPase (V-ATPase). While the PM H+-ATPase transfers protons from the cytoplasm to the apoplast, the V-ATPase pumps protons into the organelle lumen. These enzymes belong to different protein families and have distinct structures and mechanisms of action. However, they can be regulated by the same mechanisms and may coordinate in certain processes.

Summary: Copper is an essential element for humans and plants, but excessive intake may have detrimental effects on living systems. Monitoring the bioavailability and exposure levels of copper is crucial for prevention of toxicity, especially focusing on the behavior of copper in the soil-plant system.

Summary: Freshwater ecosystems are threatened by heavy metal contamination, but phytoremediation using plants can effectively remove chemical contaminants. This study examined the ability of two wetland plant species (duckweed and tape grass) to remove copper from polluted water and the subsequent leaching potential. It was found that duckweed outperformed tape grass in removing copper at low concentrations, and leaching from decaying plant material only negatively impacted snail survival at high copper concentrations and under simulated freeze-thaw cycles. The results suggest that some aquatic plants can remove contaminants without long-term leaching, but highly polluted environments may require plant tissue removal to prevent leaching.

Summary: The study revealed that the regulatory role of salicylic acid (SA) in plants under cadmium (Cd) stress involves root biological processes. Plants transformed with ThenahG gene displayed enhanced tolerance, while mutants with high endogenous SA were more sensitive to Cd stress. This tolerance was associated with antioxidative defense, flavonoid biosynthesis, metal chelation and sequestration, and cell wall modification in the roots.

Summary: This study investigates the effects of Pb(II) and Cu(II) ions on three plant species, namely Medicago sativa L., Triticum aestivum L., and Zea mays L. The comprehensive phytotoxicity assessments provide insights into the adaptability and resilience of these plant species to metal-contaminated environments. The findings have important implications for understanding plant-metal interactions and devising phytoremediation strategies in contaminated ecosystems.

Summary: This study explores the phytoremediation potential of Cannabis sativa L. in contaminated soil containing phenanthrene (PHE), pyrene (PYR), and copper (Cu). The results reveal that the removal efficiency of PHE and PYR ranged from 93% to 98% and 36% to 61%, respectively, while the highest Cu extraction reached 58 mg center dot kg(-1). The growth of C. sativa L. was significantly inhibited by the presence of contaminants, with reductions in biomass ranging from 25% to 71%. These findings contribute to the understanding of C. sativa L. as a potential phytoremediation tool for further field-scale investigations.

Summary: The toxicity of metals negatively impacts plants' growth and productivity, leading to various disruptions. Plants employ efficient mechanisms through signaling pathways to combat this stress, involving metal transporters and metal-binding proteins for detoxification. Further research on the molecular basis of metal toxicity and tolerance mechanisms is crucial for genetic engineering to produce transgenic plants that enhance phytoremediation techniques.

Summary: The study evaluated the phytoremediation potential of four grass species in the Pampa biome for soil contaminated with copper, with C. dactylon showing the best performance. High Cu concentrations had a more severe impact on A. affinis, while other species experienced decreased growth and photosynthetic rates. The findings suggest that C. dactylon is more efficient in the phytoremediation process compared to other species.

Summary: The study successfully increased the detoxification efficiency of switchgrass to 2,4-DNT using the synthetic NfsI gene, alleviating root growth inhibition and excessive ROS production. The transgenic switchgrass plants showed a 1.7-fold increase in 2,4-DNT removal efficiency compared to control plants, and may participate in 2,4-DNT detoxification through pathways mediated by NfsI.

Summary: The SHN/WIN clade of the AP2/ERF family plays a crucial role in various physiological processes in plants, and the HvSHN1 transcription factor in barley improves tolerance to salt, water stress, and heat stress. Overexpression of HvSHN1 upregulates genes involved in osmotic stress, oxidative stress, sugar metabolism, and wax biosynthesis, suggesting its potential application in improving abiotic stress tolerance.
