“…The role of silicon (Si) as a beneficial element to higher plants is known because it is a mitigator of abiotic and biotic stresses, and also brings gains in growth and production of plants (Hattori et al 2005;Resende et al 2009;Chen et al 2016;Lavinsky et al 2016;Carneiro et al 2017;Viciedo et al 2019), although plants present different capacities to accumulate Si in their tissues. Despite the importance of Si to many plants of agronomic interest, availability of this mineral element in the soil is low (Hattori et al 2005), suggesting the need for a contribution of Si through fertilization.…”

The efficiency of silicon (Si) foliar spraying in sorghum plants can be increased with new sources that may enhance the uptake of the beneficial element with reflexes in physiology. This study investigated the effect of foliar application of Si on different sources of absorption, gas exchange, and growth in sorghum plants, based on the hypothesis that there is a differential response to specific sources and concentrations of Si. An experiment was conducted in a completely randomized design with three replicates (in triplicate). The treatments consisted of five Si sources (nanosilica, silicic acid, stabilized sodium, potassium silicate, and potassium silicate) and four concentrations of Si (0, 0.5, 1.0, and 1.5 g L −1 of Si). Foliar spraying of Si on sorghum plants was effective at increasing the absorption of the beneficial element and the gas exchange of the plant. Nanosilica stood out as an alternative source of Si, and a promising option for foliar spraying in sorghum crops, as it promoted high uptake of the element by the plant. This source also promoted a high photosynthetic rate for both potassium silicate and alkaline silicate. In this study, spraying of 0.88 g L −1 (Si-alkali) and 0.84 g L −1 (Si-potassium) on sorghum at the phenological stages V 4 and V 8 (four and eight fully expanded leaves respectively) and R 1 (beginning of flowering) was promising because it increased plant growth, reduced water loss through transpiration, and had a positive impact on gas exchange.

“…It was found that the hemicellulose-bound form of Si with a negative charge is responsible for reducing Cd accumulation in rice cells via the mechanism of the (Si hemicellulose matrix) Cd complexation and co-deposition [119,120]. Furthermore, the exogenous application of Si suppressed the Cd uptake and accumulation in plants via the Si-induced antioxidative mechanism and improved plant growth and photosynthetic characteristics by lowering the reactive oxygen species (ROS) damage [121]. The Si-mediated alleviation of Cd accumulation is also attributed to its role in altering gene expression.…”

Cadmium (Cd) contamination in edible agricultural products, especially in crops, has raised worldwide concerns regarding food safety consumption. This review summarizes the current knowledge of the applicable methods and perspectives for reducing Cd contamination of agricultural products. Agricultural approaches of soil amendments, irrigation management, microbial agent, and cropping patterns were systematically concluded to illustrate the developments and achievements in crop contamination management. The use of traditional soil amendments as well as novel nano-materials has contributed to producing safe crops in agricultural soil contaminated with Cd. This review provides an inspiring and promising tool for maintaining food safety by reducing Cd accumulation in edible agricultural products

“…Currently, it is suggested that Cd-induced hormesis is closely related to the activation of antioxidant defense system in plant ( Jia et al., 2015 ; Muszyńska et al., 2018 ; Carvalho et al., 2020 ; Makowski et al., 2020 ). For instance, the exposure of Arabidopsis thaliana seedlings to a short-term Cd stress significantly induced the activities of ascorbate peroxidase (APX), catalase (CAT) and glutathione reductase (GR) ( Carneiro et al., 2017 ). The low level of Cd stress treatment induces the accumulation of responded substances, such as anthocyanins, flavonoids, phenolics, ascorbic acid and other free organic acids ( Vinogradova and Glukhov, 2021 ), they are known non-enzymatic antioxidants in plants.…”

Low-level cadmium exposure induced hormesis in peppermint young plant by constantly activating antioxidant activity based on physiological and transcriptomic analyses

As one of the most toxic environmental pollutants, cadmium (Cd) has lastingly been considered to have negative influences on plant growth and productivity. Recently, increasing studies have shown that low level of Cd exposure could induce hormetic effect which benefits to plants. However, the underlying mechanisms of Cd-triggered hormesis are poorly understood. In this study, we found that Cd stress treatment showed a hormetic effect on peppermint and Cd treatment with 1.6 mg L-1 concertation manifested best stimulative effects. To explore the hormesis mechanisms of Cd treatment, comparative transcriptome analysis of peppermint young plants under low (1.6 mg L-1) and high (6.5 mg L-1) level of Cd exposure at 0 h, 24 h and 72 h were conducted. Twelve of differentially expressed genes (DEGs) were selected for qRT-PCR validation, and the expression results confirmed the credibility of transcriptome data. KEGG analysis of DEGs showed that the phenylpropanoid biosynthesis and photosynthesis were important under both low and high level of Cd treatments. Interestingly, GO and KEGG analysis of 99 DEGs specifically induced by low level of Cd treatment at 72 h indicated that these DEGs were mainly involved in the pathway of phenylpropanoid biosynthesis and their functions were associated with antioxidant activity. The expression pattern of those genes in the phenylpropanoid biosynthesis pathway and encoding antioxidant enzymes during 72 h of Cd exposure showed that low level of Cd treatment induced a continuation in the upward trend but high level of Cd treatment caused an inverted V-shape. The changes of physiological parameters during Cd exposure were highly consistent with gene expression pattern. These results strongly demonstrate that low level of Cd exposure constantly enhanced antioxidant activity of peppermint to avoid oxidative damages caused by Cd ion, while high level of Cd stress just induced a temporary increase in antioxidant activity which was insufficient to cope with lasting Cd toxicity. Overall, the results presented in this study shed a light on the underlying mechanisms of the Cd-mediated hormesis in plant. Moreover, our study provided a safe method for the efficient utilization of mild Cd-contaminated soil as peppermint is an important cash plant.
