“…Phytotoxicity is also an expected problem after applying intensive amounts of manufactured NMs [1]. Many reports confirmed the problem of phytotoxicity in agroecosystems [156,163]. These studies have reported that excess metal-based NPs cause oxidative stress on cultivated plants through the generation of ROS, reducing plant growth, causing hormonal imbalance, and causing damage to the secondary metabolism, along with potentially genotoxic consequences [156].…”

“…It was found that applying nano-zero-valent iron (nZVI) caused toxicity to mung bean under hydroponically cultured seedlings at 600 mg L −1 [161], whereas applying more than 200 mg L −1 nZVI to Herbaceous cattail exhibited strong toxic effects [162]. Depending on the type of NPs and plant species, it was noticed that the toxic level of Fe-based NPs may range from 50 to 2000 mg L −1 [163]. Concerning the nanotoxicity on soil microbiomes, NMs have direct impacts due to their high applied dose, which reduces nutrient bioavailability.…”

“…These studies have reported that excess metal-based NPs cause oxidative stress on cultivated plants through the generation of ROS, reducing plant growth, causing hormonal imbalance, and causing damage to the secondary metabolism, along with potentially genotoxic consequences [156]. The main problem with nanotoxicity effects on environmental components is the lack of methodology to monitor and follow accurately the NPs fate in soil and different biological systems, besides the insufficient knowledge regarding reliable results [163].…”

Soil salinity is a serious global problem that threatens a high percentage of the global soils. Salinity stress can create ionic, oxidative, and osmotic stress, along with hormonal imbalances, in stressful plants. This kind of stress was investigated on agricultural productivity at different levels, starting in vitro (plant tissue culture), through hydroponics, pots, and field conditions. Several approaches were studied for managing salinity stress, including using traditional materials (e.g., gypsum, sulfur), organic amendments (e.g., compost, biochar, chitosan), and applied manufactured or engineered nanomaterials (NMs). Application of nanomaterials for ameliorating salinity stress has gained great attention due to their high efficiency, eco-friendliness, and non-toxicity, especially biological nanomaterials. The application of NMs did not only support growing stressful plants under salinity stress but also increased the yield of crops, provided an economically feasible nutrient management approach, and was environmentally robust for sustainable crop productivity. Nano-management of salinity may involve applying traditional nano-amendments, biological nanomaterials, nano-enabled nutrients, nano-organic amendments, derived smart nanostructures, and nano-tolerant plant cultivars. Producing different plant cultivars that are tolerant to salinity can be achieved using conventional breeding and plantomics technologies. In addition to the large-scale use of nanomaterials, there is an urgent need to address and treat nanotoxicity. This study aims to contribute to this growing area of research by exploring different approaches for nano-management of current practices under salinity stress under field and in vitro conditions. This study also raises many questions regarding the expected interaction between the toxic effects of salinity and NMs under such conditions. This includes whether this interaction acts positively or negatively on the cultivated plants and soil biological activity, or what regulatory ecotoxicity tests and protocols should be used in research.

“…Plant species can tolerate different degrees of stress at different times, depending on the species, their habitats, and the duration of heavy metal stress. Plant cells may die if heavy metal stress becomes a long process (Bisht et al, 2023;Lu et al, 2023;Shakoor et al, 2023;Xu et al, 2023).…”

Recent progress on the microbial mitigation of heavy metal stress in soybean: overview and implications

Plants are adapted to defend themselves through programming, reprogramming, and stress tolerance against numerous environmental stresses, including heavy metal toxicity. Heavy metal stress is a kind of abiotic stress that continuously reduces various crops’ productivity, including soybeans. Beneficial microbes play an essential role in improving plant productivity as well as mitigating abiotic stress. The simultaneous effect of abiotic stress from heavy metals on soybeans is rarely explored. Moreover, reducing metal contamination in soybean seeds through a sustainable approach is extremely needed. The present article describes the initiation of heavy metal tolerance mediated by plant inoculation with endophytes and plant growth-promoting rhizobacteria, the identification of plant transduction pathways via sensing annotation, and contemporary changes from molecular to genomics. The results suggest that the inoculation of beneficial microbes plays a significant role in rescuing soybeans under heavy metal stress. They create a dynamic, complex interaction with plants via a cascade called plant–microbial interaction. It enhances stress metal tolerance via the production of phytohormones, gene expression, and secondary metabolites. Overall, microbial inoculation is essential in mediating plant protection responses to heavy metal stress produced by a fluctuating climate.
