“…As well, in MET-treated Chinese cabbage (Brassica campestris spp. chinensis L.) plants the concentration of Cd and the expression levels of related transport gene IRT1 were significantly reduced [99]. The transcriptome analysis by Cao et al (2019) demonstrated that MET broadly altered the expressions of various genes in cucumber (Cucumis sativus L.) under Cu stress.…”

“…In MET-treated Chinese cabbage (Brassica campestris spp. chinensis L.) plants, Wang et al (2020) showed a significantly reduced concentration of Cd and expression levels of related transport genes IRT1 (regulators of Cd absorption). Under Cd toxicity, NO increases the expression of IRT1, thus further increasing the absorption of Cd and intensifying the stress of Cd in plants, while an exogenous treatment with MET under Cd toxicity inhibits the synthesis of NO, and therefore, MET reduces the Cd content in the plant and Cd toxicity as well [99].…”

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.

Effects of exogenous melatonin on the growth and cadmium accumulation of lettuce under cadmium‐stress conditions

Melatonin (MT) is a signaling molecule that is widely present in plants and can help them resist abiotic stresses. In this study, the effects of different concentrations of exogenous MT on the growth and development of lettuce (Lactuca sativa) under cadmium stress (50 μmol/L) were investigated. Based on their Cd accumulation differences, the "Hong Feng" and "Luo Ma" lettuce cultivars were selected as research materials. The results showed that different concentrations of MT could promote the growth of lettuce under 50 μmol/L cadmium stress. The application of exogenous melatonin can significantly increase the plant height, biomass, chlorophyll, soluble protein and soluble sugar content of lettuce, and increase the net photosynthetic rate. MT could also reduce the malondialdehyde content in lettuce under cadmium stress and increase the activities of superoxide dismutase, peroxidase, and catalase activities. After treatment with different concentrations of MT, the Cd content in the shoots of both cultivars significantly decreased; in contrast, the Cd content in the roots was significantly increased, which limited the transport of Cd from underground to the shoots. In addition, both Cd stress and exogenous MT induced the synthesis of endogenous MT, and 50 μmol/L MT treatment most effectively induced this response. In conclusion, this study demonstrated that MT could alleviate the negative effects of Cd stress on lettuce with different Cd accumulation differences in terms of physiological indicators. Therefore, it provides a certain reference for the potential of MT to be applied to crops threatened by heavy metals.
