Critical Reviews in Environmental Science and Technology, Journal Year: 2023, Volume and Issue: 53(20), P. 1795 - 1816

AbstractSoil pollution from potentially toxic elements (PTEs) is a serious environmental issue worldwide that affects agricultural safety and human health. Arbuscular mycorrhizal fungi (AMF), as ecosystem engineers, can alleviate PTE toxicity in crop plants. However, the comprehensive effects of AMF on performance PTE-contaminated soils have not yet been recognized globally. Here, meta-analysis 153 studies with 3213 individual observations was conducted to evaluate growth accumulation five staple crops (wheat, rice, maize, soybean, sorghum) contaminated soils. Our results demonstrated had strong positive shoot root biomass. This because effectively oxidative damage induced by PTEs stimulating photosynthesis, promoting nutrition, activating non-enzymatic enzymatic defense systems also decreased 23.6% increased 0.8%, demonstrating inhibited transfer uptake shoot. Meanwhile, AMF-mediated were weaker pH > 7.5. Overall, this global survey has essential implications ability enhance provides insights into guidelines for safe production worldwide.Keywords: fungipotentially elementscrop growthbioaccumulationphysiological activitiesmeta-analysisHANDLING EDITORS: Jörg Rinklebe Lena Q.

Effect of a harsh circular environment on self-healing microbial-induced calcium carbonate materials for preventing Pb2+ migration

Environmental Technology & Innovation, Journal Year: 2023, Volume and Issue: 32, P. 103380 - 103380

Published: Sept. 29, 2023

Microbially induced carbonate precipitation (MICP) is increasingly being explored for Pb-contaminated water bodies and soil remediation. However, the Pb-related precipitate resulting from MICP process can possibly leach acid over time when subjected to harsh environments, causing serious threats human health. In this study, first time, self-healing microbial-induced calcium (MICC) materials are proposed applied prevent Pb2+ migration where leached after spore germination, spore-vegetative cell transformation, urease secretion, urea hydrolysis, thereby producing spore-containing precipitation. This was repeated five times explore effect of a circular environment on MICC materials. Results indicated that Pb immobilization would have deteriorated if inosine trace elements had not been intervened during germination respectively. The spores vegetative cells provided extra nucleation sites minerals attach. extracellular polymeric substances (EPSs) combined with functional groups chemical bonds their surrounding environments. scanning electron microscopy–energy-dispersive X-ray spectroscopy (SEM–EDS) images also cerussite mineral precipitated prior calcite because more affinity combine CO32- OH-. An efficiency greater than 95% remained nearly same cycles, while it reduced very quickly less 10% three cycles neglecting materials, thus highlighting relative merits.

Selenium Nanoparticles Mitigate Cadmium Stress in Tomato through Enhanced Accumulation and Transport of Sulfate/Selenite and Polyamines

Journal of Agricultural and Food Chemistry, Journal Year: 2024, Volume and Issue: 72(3), P. 1473 - 1486

Accumulation of cadmium (Cd) ions in soil is an increasingly acute ecological problem agriculture production. Selenium nanoparticles (SeNPs) can mediate Cd tolerance plants; however, the underlying mechanisms remain unclear. Herein, we show that foliar application SeNPs improved adaptive capacity tomato plants to decrease Cd-induced damage. induced more roots but not shoots despite greater accumulation selenium and sulfur both tissues high selenate influx. Additionally, significantly increased thiol compounds, including glutathione, cysteine, phytochelatins, contributing enhanced detoxification. Importantly, expression sulfate transporters 1:3, S-adenosylmethionine 1 polyamine transporter 3. Then, experiments with mutants these genes showed SeNP-reduced stress largely relies on levels shoot-to-root transport selenium/sulfur polyamines. These findings highlight potential improve crop production phytoremediation heavy metal-contaminated soils.
