“…It is also found that CuO NPs decreased As uptake in rice by removing As from the solution with the precipitated complexes and consequently (Wang et al 2019). In addition to As, it is previously reported that ZnO NPs reduced the Cd concentration in wheat and rice (Bashir et al 2018, Rizwan et al 2019a. The application of ZnO NPs increased the Zn concentrations in rice shoots and roots (Fig.…”

This study describes the role of zinc oxide nanoparticles (ZnO NPs) in alleviating arsenic (As) stress in rice (Oryza sativa) germination and early seedling growth. Seeds of rice were primed with different concentrations (10, 20, 50, 100, and 200 mg L −1) of ZnO NPs and As (0, and 2 mg L −1) for 12 days in petri dishes. Two milligrams per liter of As treatment represented a stress condition, which was evidenced by germination rate, seedling length, seedling dry weight, chlorophyll, superoxide dismutase (SOD), catalase (CAT), and malondialdehyde (MDA) content of rice shoot. ZnO NPs amendment (10-100 mg L −1) increased the germination rate (2.3-8.9%), shoot weight (18.2-42.4%), root weight (5.2-23.9%), and chlorophyll content (3.5-40.1%), while elevated the SOD (2.2-22.8%) and CAT (7.2-60.7%) activities and reduced the MDA content (17.5-30.8%). As concentrations were significantly decreased by 8.4-72.3% and 10.2-56.6%, respectively, in rice roots and shoots with ZnO NPs amendment (10-200 mg L −1) by the As adsorption of ZnO NPs and promoted biomass of rice. All the amendments improved the Zn concentrations in rice shoots and roots. Overall, ZnO NPs provide effective resistance to arsenic toxicity by increasing germination, biomass, and nutrients of Zn and decreasing As uptake in rice.

“…Nevertheless, the application of Fe complex with lysine (lys) greatly reduces the toxicity induced by heavy metals stress. Fe complex with lys significantly reduced the Cd stress by improving rice growth, photosynthesis and the antioxidant system [45]. Large amounts of heavy metals in plant organs seriously affected the quality of their vegetative characters.…”

“…Because Fe is an essential micronutrient for proper plant growth and development, it plays a crucial role in plant metabolism in enzymatic and metabolic processes [1,43,44]. Conversely, Fe deficiency significantly alters the morpho-physiological characteristics of plants and results in stunned plant growth and biomass [45]. Nevertheless, the application of Fe complex with lysine (lys) greatly reduces the toxicity induced by heavy metals stress.…”

Chromium (Cr) is among the most widespread toxic trace elements found in agricultural soils due to various anthropogenic activities. However, the role of micronutrient-amino chelates on reducing Cr toxicity in crop plants was recently introduced. In the current experiment, the exogenous application of micronutrients [iron (Fe)] chelated with amino acid [lysine (lys)] was examined, using an in vivo approach that involved plant growth and biomass, photosynthetic pigments and gaseous exchange parameters, oxidative stress indicators and antioxidant response. The uptake and accumulation of Fe and Cr were determined under different levels of tannery wastewater (33, 66, 100%) used along with the exogenous supplementation of Fe-lys (5 mM) to Spinacia oleracea plants. Results revealed that tannery wastewater in the soil decreased plant growth and growth-related attributes, photosynthetic apparatus and Fe contents in different parts of the plants. In contrast, the addition of different levels of tannery wastewater to the soil significantly increased the contents of malondialdehyde (MDA), hydrogen peroxide (H2O2) and electrolyte leakage (EL), which induced oxidative damage in the roots and leaves of S. oleracea plants. However, S. oleracea plants increased the activities of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) and ascorbate peroxidase (APX), which scavenge the over-production of reactive oxygen species (ROS). Cr toxicity can be overcome by the supplementation of Fe-lys, which significantly increased plant growth and biomass, improved photosynthetic machinery and increased the activities of different antioxidative enzymes, even in the plants grown under different levels of tannery wastewater in the soil. Furthermore, the supplementation of Fe-lys increased the contents of essential nutrients (Fe) and decreased the contents of Cr in all plant parts compared to the plants cultivated in tannery wastewater without application of Fe-lys. In conclusion, the application of Fe-lys is an innovative approach to mitigate Cr stress in spinach plants, which not only increased plant growth and biomass but also decreased the Cr contents in different plant organs.

“…They are the building units of proteins, as the main component of living cells that have vital roles in many cell metabolic reactions (Kielland 1994;Rainbird et al 1984;Jones and Darrah 1993). In addition, amino acids have various important biological functions in plant cells including detoxification of toxins and heavy metals (Hussain et al 2018;Rizwan et al 2017;Bashir et al 2018), optimizing the nutrient uptake, translocation and metabolism, vitamin biosynthesis, growth biostimulation, creating higher tolerance to environmental stresses such as drought, salinity and cold conditions, as well as in the synthesis and production of aminochelate fertilizers (Jeppsen 1991;Sharma and Dietz 2006;Souri and Hatamian 2019).…”

Amino acids have various roles in plant metabolism, and exogenous application of amino acids may have benefits and stimulation effects on plant growth and quality. In this study, the growth and nutrient uptake of Romain lettuce (Lactuca sativa subvar Sahara) were evaluated under spray of glycine or glutamine at different concentrations of 0 (as control), 250, 500 and 1000 mg.L-1, as well as a treatment of 250 mg.L-1 glycine+250 mg.L-1 glutamine. The results showed that there was significant increase in leaf total chlorophyll content under Gly250+Glu250, Gly250 and Glu1000 mg.L-1treatments, and in leaf carotenoids content under 250 mg.L-1 glutamine spray compared with the control plants. Shoot fresh and dry weights were highest under 500 mg.L-1 glycine, whereas root fresh weight was highest under 250 mg.L-1 glycine spray. Foliar application of glycine and glutamine had no significant increase in leaf mineral concentrations except for iron, in which 1000 mg.L-1Gly spray resulted in significantly higher leaf Fe concentration compared with the control plants. Leaf vitamin C was increased at 250 and particularly 500 mg.L-1 spray of glycine and glutamine compared with the control. Nevertheless, different amino acid treatments had no significant effect on plant height, leaf SPAD value, root dry weight, and leaf concentrations of N, K, Ca, Mg and Zn. The results indicate that foliar application of glycine and glutamine amino acids can have beneficial effects on lettuce growth, as higher fresh yield, leaf chlorophyll content and vitamin C were obtained by low to moderate concentrations of glycine and/or glutamine amino acids.
