Other claims from this paper (11)
- Intervention effect Chromium stress caused oxidative damage, leading to overproduction of electrolyte leakage, hydrogen peroxide and malondialdehyde.
- Intervention effect Fe NPs significantly improved plant growth, biomass and yield.
- Intervention effect Fe NPs significantly improved photosynthetic activity by enhancing chlorophyll contents.
- Intervention effect Application of Fe NPs reduced the uptake and accumulation of Cr in the plants.
- Intervention effect Fe NPs decreased oxidative damage compared with plants without Fe NPs treatments.
- Intervention effect Fe NPs enhanced the enzymatic and non-enzymatic activity in the plant to withstand Cr stress compared with plants without Fe NPs.
- Mechanism Inoculation with the chromium-resistant bacterium S. aureus further enhanced the positive impact of Fe NPs by transforming toxic chromium (Cr6+) into a less toxic form (Cr3+).
- Intervention effect Bacterial inoculation reduced Cr uptake by plants through adsorption of Cr ions, decreasing chromium ion bioavailability.
- Intervention effect At 100 mg/kg chromium, foliar application of Fe NPs from 0 to 20 mg/L increased the total chlorophyll contents from 2.8 to 3.9.
- Intervention effect Application of S. aureus further enhanced the chlorophyll contents from 4.4 to 5.4.
- Recommendation Combining Fe NPs and S. aureus could be a viable strategy for reducing Cr toxicity and accumulation in rice plants.
