“…Cadmium can be taken through plant roots and transferred to different tissues of the plant [13]. Higher accumulations of Cd in plants have negative effects such as chlorosis, inhabitation of plant growth, nutrient absorption and metabolism, nutrient imbalances, cellular ultrastructure deformation and destruction of organelles, and accumulation of "reactive oxygen species" (ROS), which all trigger plants to die off [12][13][14][15][16]. Higher Cd stress or concentration in plants can enhance stress, such as the accumulation of "reactive oxygen species" (ROS) in plants, which is a major evidence of Cd poisoning [12].…”

This study aimed to investigate the physiological and cellular mechanisms of Sesuvium portulacastrum under heavy metal stress to evaluate possible tolerance and adaptation mechanisms in a metal-polluted environment. The physiological and cellular ultrastructural responses of S. portulacastrum were studied hydroponically under exposure to a range of cadmium (Cd) concentrations (50 µM to 600 µM) for 28 days. The activity of antioxidant enzymes like catalase (CAT), superoxide dismutase (SOD), and peroxidase (POD), changes in chlorophyll, and cellular ultrastructural content were examined. There was no significant difference in chlorophyll content in the leaf under the stress of 300 μM, but 400 μM and 600 μM Cd stress showed significantly decreased chlorophyll content. The SOD activity indicates an increase under the Cd stress of 100 μM for leaves, 300 μM for stems, and 50 μM for roots; after that, the SOD activity gradually decreased with increasing Cd concentrations. But POD activity was considerably increased with increasing Cd stress. CAT activity showed a gradual increase in concentrations until 300 μM of Cd stress and then decreased sharply in roots, stems, and leaf tissues. Cd stress had a considerable impact on the structure of the roots, stems, and leaves cells, such as distorted and thinner cell walls and the deformation of chloroplasts, mitochondria, and other organelles. Therefore, the increased number of nucleolus in the cell nucleus suggests that cells may be able to maintain their protein synthesis in a stressful environment. This study concludes that SOD is the dominant antioxidant enzyme activity during low Cd toxicity (<100 μM), while POD is the dominant enzyme activity during higher Cd toxicity (>100 μM).

“…In addition, it has been shown that plant defense stimulation of products based on seaweeds (such as A. nodosum ) is triggered by cell walls and allows the storage of polysaccharides (ulvans, alginates, fucans, laminarin and carrageenans) that will alleviate biotic stresses (Vera et al, 2011). More specifically, Hasanuzzaman et al (2023) demonstrated that A. nodosum extracts increased the Cd toxicity tolerance of plants, inducing an increase in plant biomass. BG treatment can also lead to improve growth, stress tolerance, yield, and nutrient uptake (Mondragón‐Valero et al, 2019; Pascoalino et al, 2021; Saa et al, 2015; Torres et al, 2015).…”

“…It is a biostimulant and plant defense stimulator. Boralgine ® contains Ascophyllum nodosum extracts which include a wide array of inorganic components, namely nitrogen, phosphorus, potassium, magnesium, calcium, iron, zinc, and sulfur, along with organic substances such as betaines, polysaccharides like alginates, fucoidans, laminarans, as well as vitamins, phenolic compounds, and other bioactive secondary metabolites (Hasanuzzaman et al, 2023). Thus, specialized metabolic pathways could be activated.…”

One of the challenges of agromining is the adoption of more environmentally‐friendly solutions to improve plant biomass yields and Ni concentrations in plants. Here, we focused on four sustainable solutions for optimizing nickel phytoextraction by the hyperaccumulator Odontarrhena chalcidica: a biostimulant, another biostimulant/plant defense stimulator, artificial root exudates, and a biodegradable metal chelator. Their effects on the growth and physiology of O. chalcidica, on Ni phytoextraction capacity, on physicochemical soil characteristics, and on the diversity of rhizosphere and endophytic bacteria were compared to a conventional mineral fertilizer. A 5‐month pot experiment was carried out with O. chalcidica growing on an ultramafic soil. Element concentrations in both soil and plant were measured. Moreover, numerous compounds were analyzed (photosynthetic pigments, malondialdehyde, flavonoids, free amino acids, and starch). We also characterized rhizosphere and endophytic bacterial communities associated with this hyperaccumulator. Biostimulants appeared to be a promising way of improving Ni concentration in shoots and plant biomass production, and showed a positive effect on bacterial richness and diversity. In contrast, our experiments did not show that artificial exudates and mineral fertilizer had a positive effect on Ni phytoextraction. Finally, the biodegradable chelator had no significant effect. The use of sustainable amendments into a Ni agromining system improved both plant biomass and Ni yields, in comparison to mineral fertilization. Thus, improving agromining by replacing mineral fertilizers would be an eco‐efficient strategy.

“…When maize seedlings are subjected to Cd stress, plant growth is inhibited, leaves turn yellow and curl, aboveground biomass is significantly reduced, and Cd's inhibition of the root is the most obvious [22,23]. The plant cannot carry out normal photosynthesis and transpiration, thus inhibiting the growth and development of the plant [24][25][26][27].…”

Heavy metal (HM) contamination poses a serious threat to safe crop production and human health, and different maize inbred lines respond differently to cadmium (Cd) stress. However, the morphological and physiological characteristics of maize inbred lines seedlings are not clear under Cd stress. In this study, we analyzed the agronomic traits and physiological and biochemical indices of inbred maize seedlings under Cd stress in the seedling stage using the inbred lines Kui3, CML118, Mo17, B73, and B77 as the materials. These five inbred maizes were treated with five different concentrations of Cd (0, 1, 3, 5, and 7 mg L−1, respectively) were applied and the indices of the maize seedlings determined on day 15. The aboveground and belowground biomass of five maize inbred lines seedlings showed a decreasing trend under Cd stress. Leaf relative water content and SPAD values also decreased, but the overall decrease in relative water content was small, and the differences were not significant. Surprisingly, Cd stress affected the activities of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT), leading to enhanced mem-brane lipid peroxidation. The cadmium content varied greatly between varieties under Cd stress, but all of them had lower Cd content above ground than below ground, and the varieties with the highest and lowest transfer coefficients were Mo17 (0.33–0.83) and B73 (0.06–0.44), respectively. Kui3 had the greatest difference in soluble protein content under Cd stress, which showed a de-creasing trend, and the soluble sugar content was significantly decreased in general compared to that of CK. The soluble sugar content was higher than CK under Cd treatment, and the proline content of the maize seedlings of all of the inbred lines showed an increasing trend compared to CK. Overall, there were significant genotypic differences in the Cd stress response to Cd toxicity in the maize inbred lines seedlings, and, in general, this study helps us to understand the mechanism of maize inbred lines seedlings response to Cd stress. It provides a theoretical basis for the se-lection and breeding of varieties, and food safety.
