“…Furthermore, the increased levels of MDA and cuticle damage by As V stress corresponded with increased electrolyte leakage and water loss in d10 and d17 shoots (Figure 4f,g). These findings clearly showed that As V treatments caused considerable oxidative damage in SL-deficient mutant plants, confirming that ROS-induced oxidative stress is one of As V 's lethal effects in rice (Figure 7), as also observed in many arsenic-susceptible cultivars such as maize (Zea mays) and barley [49,52,60]. The cellular antioxidant system comprising both enzymatic and non-enzymatic arsenals plays crucial roles in relieving the oxidative burden in plant tissues under stressful conditions.…”

“…We were then curious as to why these mutants were more vulnerable to arsenic and what mechanisms might be responsible for WT's superior performance under high As V stress circumstances. Because arsenic is a non-essential, hazardous element for plant growth and metabolism, its accumulation in tissues, even at low concentrations, can impair developmental processes in crop plants, including rice, wheat and mustard (Brassica juncea) [49][50][51]. Indeed, it was noticed that both the WT and SL-depleted mutants displayed growth defects in an As V concentration-dependent manner.…”

Metalloid contamination, such as arsenic poisoning, poses a significant environmental problem, reducing plant productivity and putting human health at risk. Phytohormones are known to regulate arsenic stress; however, the function of strigolactones (SLs) in arsenic stress tolerance in rice is rarely investigated. Here, we investigated shoot responses of wild-type (WT) and SL-deficient d10 and d17 rice mutants under arsenate stress to elucidate SLs’ roles in rice adaptation to arsenic. Under arsenate stress, the d10 and d17 mutants displayed severe growth abnormalities, including phenotypic aberrations, chlorosis and biomass loss, relative to WT. Arsenate stress activated the SL-biosynthetic pathway by enhancing the expression of SL-biosynthetic genes D10 and D17 in WT shoots. No differences in arsenic levels between WT and SL-biosynthetic mutants were found from Inductively Coupled Plasma-Mass Spectrometry analysis, demonstrating that the greater growth defects of mutant plants did not result from accumulated arsenic in shoots. The d10 and d17 plants had higher levels of reactive oxygen species, water loss, electrolyte leakage and membrane damage but lower activities of superoxide dismutase, ascorbate peroxidase, glutathione peroxidase and glutathione S-transferase than did the WT, implying that arsenate caused substantial oxidative stress in the SL mutants. Furthermore, WT plants had higher glutathione (GSH) contents and transcript levels of OsGSH1, OsGSH2, OsPCS1 and OsABCC1 in their shoots, indicating an upregulation of GSH-assisted arsenic sequestration into vacuoles. We conclude that arsenate stress activated SL biosynthesis, which led to enhanced arsenate tolerance through the stimulation of cellular antioxidant defense systems and vacuolar sequestration of arsenic, suggesting a novel role for SLs in rice adaptation to arsenic stress. Our findings have significant implications in the development of arsenic-resistant rice varieties for safe and sustainable rice production in arsenic-polluted soils.

“…Crop plants face metal(loid)s stress in fields if the soil has higher than recommended safe levels of metal(loid)s or if the irrigation water has excessive metal(loid) load. A number of reports on metal(loid)s accumulation in crop plants have surfaced over the years, and the issue of metal(loid) contamination of crop plants and food products is a serious threat to the health of humans (Srivastava et al, 2020;Yadav et al, 2021). The affected crop plants include rice, wheat, maize, potato, spinach, etc.…”

The widespread occurrence of metal and metalloid in water resources and crop plants beyond the maximum permissible limits is a concerning issue for environmental and human health. There is a need to develop efficient, low-cost methods for the clean-up of water to ensure a safe drinking water supply. Further, the methods should be robust enough to clean up contaminated groundwater resources and prevent continuing metal(loid) build-up in soil. In addition, the existing metal(loid) contamination of soil also needs remediation through suitable technologies to avoid metal(loid) accumulation in crop plants. There has been a plethora of research on metal(loid) remediation, and a number of physical, chemical, and biological methods have been developed. The world today, however, is focused on and is marching rapidly towards the methods based on nanoparticles (NPs). This is because NPs are extremely effective in the remediation process, can be used easily in various forms and proportions, and have low-cost considering their lifetime and multiple cycle use. Nanoparticles can adsorb metal(loids) in soil and reduce their bioavailable levels to the crop plants. Further, the application of NPs in fields has been found to positively stimulate plants' growth and augment tolerance of plants to a variety of stresses. Further, NPS-based clean-up methods, columns and filters have been developed for contaminated water. Therefore, the nanoremediation of metal(loids) holds promise and this review article discusses the pros and cons of this.

“…Whereas under heavy metal toxicity overproduction of reactive oxygen species (ROS) and redox imbalance alters the energetic ratio of ATD/ADP, NADP/NADPH and NAD/NADH. Plant's compromised energetic balance are suggested as major factors related to heavy metal stress ( Srivastava et al., 2013 ; Yadav et al., 2021 ). It becomes clear that the study of abiotic stress in plants cannot be carried out as a single effect but as a whole, and the crosstalk between the different signal transduction responses must be considered to obtain a general picture ( Yadav et al., 2021 ).…”
