Increased use of engineered nanoparticles (NPs) is likely to result in their continued release into the environment. Some nanoparticles including zinc oxide nanoparticles (ZnO-NPs) can be toxic to eukaryotic cells, but presently little is known about ZnO-NPs effects on plants and organisms symbiotically associated them. Under in vitro conditions, we examined the effect of 4 nm ZnO-NPs on carrots roots and arbuscular mycorrhizal fungi (AMF), which are obligate biotrophs that play an essential role in mineral uptake. During 4 weeks of incubation, roots in the control treatment (0μg ml-1 ZnO) grew 30 ± 8 cm, while growth was negligible …
