Other claims from this paper (8)
- Intervention effect Nanosilver exposure in soil decreased the archaea community by more than 30% in relative abundance in the maize rhizosphere.
- Intervention effect Nanosilver compromised the involvement of archaea in nitrogen cycling and nitrification, as the authors infer.
- Intervention effect Certain potentially phytopathogenic fungal groups showed significantly increased abundances after nanosilver exposure in maize rhizosphere soil.
- Mechanism The increase in potentially phytopathogenic fungi is possibly due to negative effects of nanosilver on bacteria that exert natural biocontrol against them.
- Association A network analysis showed negative interactions between bacteria and fungi in the maize rhizosphere.
- Intervention effect Nanosilver exposure increased transcript abundance of aquaporin and phytohormone genes in maize.
- Intervention effect Nanosilver exposure may stimulate maize root growth through hormesis, as the authors suggest.
- Recommendation The authors recommend including the microbiome when assessing the risk of nano-enabled agriculture.
