“…Mycorrhizae can increase As tolerance by enhancing nutrient uptake, improving water use efficiency, and directly immobilizing As in the soil [ 160 ]. Recently, it has been reported using axenically cultivable fungus S. indica in highly As-contaminated agricultural soil may reduce arsenic stress and accumulation in rice plants through modulation in iron (Fe) homeostasis [ 161 ]. Besides, the application of biochar, a charcoal-like substance made from biomass, can provide a habitat for beneficial microorganisms and adsorb As, thereby reducing its bioavailability to plants [ 162 ].…”

“…4) Improved physiological function: AMF can mitigate the oxidative stress induced by As, enhance the activity of the antioxidant enzyme system, and improve photosynthesis. By reducing the production of hydrogen peroxide (H 2 O 2 ) and lipid peroxidation, AMF effectively countered oxidative damage in host plants (Shukla et al, 2023;Zhou et al, 2023). This symbiotic relationship significantly increased the activity of essential antioxidant enzymes, including catalase (CAT), peroxidase (POD), and superoxide dismutase (SOD) Garg, 2022, 2024;Mitra et al, 2022).…”

AMF facilitated the restoration of pigment levels, including chlorophyll a, chlorophyll b, and carotenoids, and enhanced photosynthetic efficiency, transpiration rates, and water use efficiency under conditions of As stress (Zhang et al, 2022;Shukla et al, 2023).…”

Arsenic (As) accumulation in plants is a global concern. Although the application of arbuscular mycorrhizal fungi (AMF) has been suggested as a potential solution to decrease As concentration in plants, there is currently a gap in a comprehensive, quantitative assessment of the abiotic and biotic factors influencing As accumulation. A meta-analysis was performed to quantitatively investigate the findings of 76 publications on the impacts of AMF, plant properties, and soil on As accumulation in plants. Results showed a significant dose-dependent As reduction with higher mycorrhizal infection rates, leading to a 19.3% decrease in As concentration. AMF reduced As(V) by 19.4% but increased dimethylarsenic acid (DMA) by 50.8%. AMF significantly decreased grain As concentration by 34.1%. AMF also improved plant P concentration and dry biomass by 33.0% and 62.0%, respectively. The most significant reducing effects of As on AMF properties were seen in single inoculation and experiments with intermediate durations. Additionally, the benefits of AMF were significantly enhanced when soil texture, soil organic carbon (SOC), pH level, Olsen-P, and DTPA-As were sandy soil, 0.8%–1.5%, ≥7.5, ≥9.1 mg/kg, and 30–60 mg/kg, respectively. AMF increased easily extractable glomalin-related soil protein (EE-GRSP) and total glomalin-related soil protein (T-GRSP) by 23.0% and 28.0%, respectively. Overall, the investigated factors had significant implications in developing AMF-based methods for alleviating the negative effects of As stress on plants.

“…Arsenic toxicity leads to reactive oxygen species (ROS) accumulation, which in turn causes cell membrane lipid peroxidation, cell damage or death, damage to DNA and protein structure, and stomatal conductance reduction [ 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 ]. At the same time, reactive nitrogen species (RNS) are also induced by As toxicity, leading to nitrification stress and inhibition of respiration [ 31 ].…”

Arsenic (As) is a metalloid environmental pollutant ubiquitous in nature that causes chronic and irreversible poisoning to humans through its bioaccumulation in the trophic chain. Rice, the staple food crop for 350 million people worldwide, accumulates As more easily compared to other cereal crops due to its growth characteristics. Therefore, an in-depth understanding of the molecular regulatory mechanisms underlying As uptake, transport, and detoxification in rice is of great significance to solving the issue of As bioaccumulation in rice, improving its quality and safety and protecting human health. This review summarizes recent studies on the molecular mechanisms of As toxicity, uptake, transport, redistribution, regulation, and detoxification in rice. It aims to provide novel insights and approaches for preventing and controlling As bioaccumulation in rice plants, especially reducing As accumulation in rice grains.
