“…Phytoremediation technology: Phytoremediation refers to planting plants in contaminated soil and relying on solar energy to remove heavy metals in the soil or stabilize it in a harmless state [25]. The essence is to use the microorganisms in plants and soil to reduce the concentration or toxic effects of pollutants in the environment.…”

With the acceleration of industrialization, heavy metal pollution, as one of the major types of soil pollution, is more and more serious. Therefore, the remediation of heavy metal contaminated soil has become a hotspot. This study explored the global scientific literature on the remediation of heavy metal contaminated soils, and conducted statistical and bibliometric analysis of 5733 documents in the core collection of Web of Science. The topics searched are: "Soil", Heavy metal" and "Remediation". The relationship among keywords, authors, countries, and publications for the remediation of heavy metal contaminated soils were showed in the knowledge map. Furthermore, the research hotspot evolution path of soil heavy metal remediation, the research status and development trend of related remediation technologies were analyzed. These results visualize the research results through bibliometrics, examine the research in this field from the perspective of the knowledge graph, and provide references for future development.

“…Currently, Sedum alfredii ( Hu et al, 2019 ), Solanum nigrum ( Dou et al, 2020 ), and Bidens pilosa ( Dou et al, 2019 ) have been studied extensively as hyperaccumulators based on their ability to grow in Cd-rich soils and to accumulate large amounts of Cd. In addition, cultivating low Cd crop varieties is one of the most effective ways of reducing the human health risk, and a great deal of research has been conducted on crops, such as rice ( Liu C. et al, 2020 ) and wheat ( Liu N. et al, 2020 ).…”

The toxic heavy metal cadmium (Cd) is easily absorbed and accumulated in crops and affects human health through the food chains. Sunflower (Helianthus annuus L.) is a globally important oil crop. In this study, two sunflower cultivars 62\3 (high Cd) and JB231AC (low Cd), were chosen to compare physiological and transcriptomic responses at different Cd concentrations (0, 25, 50, and 100 μM). The results showed that JB231AC had better Cd tolerance than 62\3. The contents of H2O2 and MDA (malondialdehyde) in 62\3 were lower than that in JB231AC under Cd stress, but the activities of SOD (superoxide dismutase) and POD (peroxidase) in JB231AC were higher than in 62\3, which indicated that JB231AC had a strong ability to remove reactive oxygen species (ROS)-induced toxic substances. Many deferentially expressed ABC (ATP-binding cassette) and ZIP (Zn-regulated transporter, Iron-regulated transporter-like protein) genes indicated that the two gene families might play important roles in different levels of Cd accumulation in the two cultivars. One up-regulated NRAMP (Natural resistance-associated macrophage protein) gene was identified and had a higher expression level in 62\3. These results provide valuable information to further understand the mechanism of Cd accumulation and provide insights into breeding new low Cd sunflower cultivars.

“…The ratio of metal removal from soil by plants changes widely and is related to plant species, plant growth rate, and the concentration of heavy metals in the irrigation water or soil [ 2 , 3 ]. Currently, the most recent research interests are on finding plants known as heavy metal-hyperaccumulator plants, i.e., plants which have an extreme ability to accumulate one or more heavy metals [ 4 , 5 , 6 ], to provide an immediate solution for the recovery of contaminated soils.…”

ROS and NO Phytomelatonin-Induced Signaling Mechanisms under Metal Toxicity in Plants: A Review

et al. 2021

Metal toxicity in soils, along with water runoff, are increasing environmental problems that affect agriculture directly and, in turn, human health. In light of finding a suitable and urgent solution, research on plant treatments with specific compounds that can help mitigate these effects has increased, and thus the exogenous application of melatonin (MET) and its role in alleviating the negative effects of metal toxicity in plants, have become more important in the last few years. MET is an important plant-related response molecule involved in growth, development, and reproduction, and in the induction of different stress-related key factors in plants. It has been shown that MET plays a protective role against the toxic effects induced by different metals (Pb, Cd, Cu, Zn, B, Al, V, Ni, La, As, and Cr) by regulating both the enzymatic and non-enzymatic antioxidant plant defense systems. In addition, MET interacts with many other signaling molecules, such as reactive oxygen species (ROS) and nitric oxide (NO) and participates in a wide variety of physiological reactions. Furthermore, MET treatment enhances osmoregulation and photosynthetic efficiency, and increases the concentration of other important antioxidants such as phenolic compounds, flavonoids, polyamines (PAs), and carotenoid compounds. Some recent studies have shown that MET appeared to be involved in the regulation of metal transport in plants, and lastly, various studies have confirmed that MET significantly upregulated stress tolerance-related genes. Despite all the knowledge acquired over the years, there is still more to know about how MET is involved in the metal toxicity tolerance of plants.
