“…Individual applications of MLT or H 2 S alleviated the Cd-induced decrease in plant biomass and they acted synergistically. The results are similar to the findings of Altaf et al 43 and Kaya et al, 18 where the authors observed an increase in biomass in response to the individual applications of MLT or H 2 S. Similarly, the application of MLT and H 2 S is reported to enhance the growth of plants grown under Cd stress condition. 44 , 45 The improvement in the plant biomass in response to the application of H 2 S and MLT is strongly linked with the antioxidative ability of MLT and the unique properties of H 2 S.…”

“… 17 The use of signaling molecules as soil, plant or seed application has been investigated as a potential remedy for the detrimental effects of HMs toxicity on plants. 18 Application of H 2 S is reported to improve the heavy metal tolerance in crop plants such as tomato 13 and tomato 19 etc. Notably, numerous studies have demonstrated that MLT can regulate plant growth and HMs stress responses through interactions with other signaling molecules such as H 2 S. 11 , 20 The interactive effects of MT and H 2 S were evaluated by Haghi et al 20 and found that MLT and H 2 S interaction provided relief from lead (Pb) induced oxidative stress in safflower plants by reducing the Pb uptake and regulating the ascorbate-glutathione cycle.…”

Ornamental crops particularly cut flowers are considered sensitive to heavy metals (HMs) induced oxidative stress condition. Melatonin (MLT) is a versatile phytohormone with the ability to mitigate abiotic stresses induced oxidative stress in plants. Similarly, signaling molecules such as hydrogen sulfide (H 2 S) have emerged as potential options for resolving HMs related problems in plants. The mechanisms underlying the combined application of MLT and H 2 S are not yet explored. Therefore, we evaluated the ability of individual and combined applications of MLT (100 μM) and H 2 S in the form of sodium hydrosulfide (NaHS), a donor of H 2 S, (1.5 mM) to alleviate cadmium (Cd) stress (50 mg L −1 ) in stock ( Matthiola incana L.) plants by measuring various morpho-physiological and biochemical characteristics. The results depicted that Cd-stress inhibited growth, photosynthesis and induced Cd-associated oxidative stress as depicted by excessive ROS accumulation. Combined application of MLT and H 2 S efficiently recovered all these attributes. Furthermore, Cd stress-induced oxidative stress markers including electrolyte leakage, malondialdehyde, and hydrogen peroxide are partially reversed in Cd-stressed plants by MLT and H 2 S application. This might be attributed to MLT or H 2 S induced antioxidant plant defense activities, which effectively reduce the severity of oxidative stress indicators. Overall, MLT and H 2 S supplementation, favorably regulated Cd tolerance in stock; yet, the combined use had a greater effect on Cd tolerance than the independent application.

“…The H 2 O 2 formed is then converted into H 2 O and O 2 by CAT in peroxisomes and mitochondria [ 42 ]. Additionally, peroxidases play a key role in the removal of H 2 O 2 in plants through its various cellular types [ 43 ]. We observed that B addition mitigated Cu excess-induced decreases of CAT activities in leaves and roots, and SOD (GuPX) activity in roots (in leaves), and increases of SOD (GuPX) activity in leaves (roots) ( Figure 2 ).…”

Citrus is mainly cultivated in acid soil with low boron (B) and high copper (Cu). In this study, Citrus sinensis seedlings were submitted to 0.5 (control) or 350 μM Cu (Cu excess or Cu exposure) and 2.5, 10, or 25 μM B for 24 weeks. Thereafter, H2O2 production rate (HPR), superoxide production rate (SAPR), malondialdehyde, methylglyoxal, and reactive oxygen species (ROS) and methylglyoxal detoxification systems were measured in leaves and roots in order to test the hypothesis that B addition mitigated Cu excess-induced oxidative damage in leaves and roots by reducing the Cu excess-induced formation and accumulation of ROS and MG and by counteracting the impairments of Cu excess on ROS and methylglyoxal detoxification systems. Cu and B treatments displayed an interactive influence on ROS and methylglyoxal formation and their detoxification systems. Cu excess increased the HPR, SAPR, methylglyoxal level, and malondialdehyde level by 10.9% (54.3%), 38.9% (31.4%), 50.3% (24.9%), and 312.4% (585.4%), respectively, in leaves (roots) of 2.5 μM B-treated seedlings, while it only increased the malondialdehyde level by 48.5% (97.8%) in leaves (roots) of 25 μM B-treated seedlings. Additionally, B addition counteracted the impairments of Cu excess on antioxidant enzymes, ascorbate-glutathione cycle, sulfur metabolism-related enzymes, sulfur-containing compounds, and methylglyoxal detoxification system, thereby protecting the leaves and roots of Cu-exposed seedlings against oxidative damage via the coordinated actions of ROS and methylglyoxal removal systems. Our findings corroborated the hypothesis that B addition alleviated Cu excess-induced oxidative damage in leaves and roots by decreasing the Cu excess-induced formation and accumulation of ROS and MG and by lessening the impairments of Cu excess on their detoxification systems. Further analysis indicated that the pathways involved in the B-induced amelioration of oxidative stress caused by Cu excess differed between leaves and roots.

“…In plants, melatonin was firstly detected in 1995 (26,27). Since then, it was found in various plant species and their different tissue parts, such as rice, wheat, tomato, apple, strawberry, grape, pepper, cucumber, and solanaceous, etc (28)(29)(30)(31)(32)(33)(34)(35)(36). Melatonin acts a key molecule to mediate multiple physiological processes, such as the alleviation of abiotic and biotic stresses, and plant growth and development (37)(38)(39)(40)(41)(42).…”

Fruits and vegetables contain numerous nutrients, such as vitamins, minerals, phenolic compounds, and dietary fibers. They reduce the incidence of cardiovascular diseases and the risk of certain chronic diseases, and improve the antioxidant and anti-inflammatory capacity. Moreover, melatonin was found in various fruits and vegetables species. Melatonin acts as a multifunctional compound to participate in various physiological processes. In recent years, many advances have been found that melatonin is also appraised as a key modulator on the fruits and vegetables post-harvest preservation. Fruits and vegetables post-harvest usually elicit reactive oxygen species (ROS) generation and accumulation. Excess ROS stimulate cell damage, protein structure destruction, and tissue aging, and thereby reducing their quality. Numerous studies find that exogenous application of melatonin modulates ROS homeostasis by regulating the antioxidant enzymes and non-enzymatic antioxidants systems. Further evidences reveal that melatonin often interacts with hormones and other signaling molecules, such as ROS, nitric oxide (NO), hydrogen sulfide (H2S), and etc. Among these ‘new’ molecules, crosstalks of melatonin and ROS, especially the H2O2 produced by RBOHs, are provided in fruits and vegetables post-harvest preservation in this review. It will provide reference for complicated integration of both melatonin and ROS as signal molecules in future study.
