摘要： Background: Nutrient-containing nanomaterials have been developed as fertilizers to foster plant growth and agricultural yield through root applications. However, if applied through leaves, how these nanomaterials, e.g gamma-Fe2O3 nanoparticles (NPs), influence the plant growth and health are largely unknown. This study is aimed to assess the effects of foliar-applied gamma-Fe2O3 NPs and their ionic counterparts on plant physiology of Citrus maxima and the associated mechanisms. Results: No significant changes of chlorophyll content and root activity were observed upon the exposure of 20-100 mg/L gamma-Fe2O3 NPs and Fe3+. In C. maxima roots, no oxidative stress occurred under all Fe treatments. In the shoots, 20 and 50 mg/L gamma-Fe2O3 NPs did not induce oxidative stress while 100 mg/L gamma-Fe2O3 NPs did. Furthermore, there was a positive correlation between the dosages of gamma-Fe2O3 NPs and Fe3+ and iron accumulation in shoots. However, the accumulated iron in shoots was not translocated down to roots. We observed down-regulation of ferric-chelate reductase (FRO2) gene expression exposed to gamma-Fe2O3 NPs and Fe3+ treatments. The gene expression of a Fe2+ transporter, Nramp3, was down regulated as well under gamma-Fe2O3 NPs exposure. Although 100 mg/L gamma-Fe2O3 NPs and 20-100 mg/L -Fe3+ led to higher wax content, genes associated with wax formation (WIN1) and transport (ABCG12) were downregulated or unchanged compared to the control. Conclusions: Our results showed that both gamma-Fe2O3 NPs and -Fe3+ exposure via foliar spray had an inconsequential effect on plant growth, but gamma-Fe2O3 NPs can reduce nutrient loss due to their the strong adsorption ability. C. maxima plants exposed to gamma-Fe2O3 NPs and Fe3+ were in iron-replete status. Moreover, the biosynthesis and transport of wax is a collaborative and multigene controlled process. This study compared the various effects of gamma-Fe2O3 NPs, Fe3+ and Fe chelate and exhibited the advantages of NPs as a foliar fertilizer, laying the foundation for the future applications of nutrient-containing nanomaterials in agriculture and horticulture.
