Iron Oxide and Titanium Dioxide Nanoparticle Effects on Plant Performance and Root Associated Microbes
In this study, we investigated the effect of positively and negatively charged Fe(3)O(4) and TiO(2) nanoparticles (NPs) on the growth of soybean plants (Glycine max.) and their root associated soil microbes. Soybean plants were grown in a greenhouse for six weeks after application of different amoun...

description | In this study, we investigated the effect of positively and negatively charged Fe(3)O(4) and TiO(2) nanoparticles (NPs) on the growth of soybean plants (Glycine max.) and their root associated soil microbes. Soybean plants were grown in a greenhouse for six weeks after application of different amounts of NPs, and plant growth and nutrient content were examined. Roots were analyzed for colonization by arbuscular mycorrhizal (AM) fungi and nodule-forming nitrogen fixing bacteria using DNA-based techniques. We found that plant growth was significantly lower with the application of TiO(2) as compared to Fe(3)O(4) NPs. The leaf carbon was also marginally significant lower in plants treated with TiO(2) NPs; however, leaf phosphorus was reduced in plants treated with Fe(3)O(4). We found no effects of NP type, concentration, or charge on the community structure of either rhizobia or AM fungi colonizing plant roots. However, the charge of the Fe(3)O(4) NPs affected both colonization of the root system by rhizobia as well as leaf phosphorus content. Our results indicate that the type of NP can affect plant growth and nutrient content in an agriculturally important crop species, and that the charge of these particles influences the colonization of the root system by nitrogen-fixing bacteria. |
