Bioavailability of nanoparticulate hematite to Arabidopsis thaliana

摘要: Abstract The environmental effects and bioavailability of nanoparticulate iron (Fe) to plants are currently unknown. Here, plant synthesized hematite Fe nanoparticles was evaluated using Arabidopsis thaliana ( A. thaliana ) as a model. Over 56-days growing wild-type , the nanoparticle-Fe no-Fe treatments had lower biomass, chlorophyll concentrations, internal concentrations than Fe-treatment. Results for were consistently similar throughout experiment. These results suggest that (mean diameter 40.9 nm, range 22.3–67.0 nm) not taken up therefore bioavailable . 14-days transgenic (Type I/II proton pump overexpression) Type I grew more in treatment, suggesting cope better with limitation; however, growth all types.
