Abstract:
... The impacts of iron oxide nanoparticles (γ-Fe2O3 NPs) and ferric ions (Fe³⁺) on plant growth and molecular responses associated with the transformation and transport of Fe²⁺ were poorly understood. This study comprehensively compared and evaluated the physiological and molecular changes of Citrus maxima plants as affected by different levels of γ-Fe2O3 NPs and Fe³⁺. We found that γ-Fe2O3 NPs could ...

Abstract:
... Manganese (Mn)-intolerant ‘Sour pummelo’ (Citrus grandis) and Mn-tolerant ‘Xuegan’ (Citrus sinensis) seedlings were irrigated for 17 weeks with 2 (control) or 600μM (Mn-toxicity or −excess) MnSO4. C. sinensis had higher Mn-tolerance than C. grandis, as indicated by the higher photosynthesis rates in Mn-excess C. sinensis leaves. Under Mn-toxicity, Mn levels were similar between C. sinensis and C. ...
