“…Cobalt ferrite (CoFe 2 O 4 ) and γ-Fe 2 O 3 NMs increased the number of nodules by the regulation of reactive oxygen species (ROS) content in the nodules as nitrogenase and rhizobia are sensitive to ROS. , In addition, NMs have been extensively proven to elicit flavonoids in vitro cultures of diverse plant species. Kalisz et al found that foliar spray with 1.5% Fe 2 O 3 and cerium oxide NMs increased flavonoid concentrations in lettuce and sweet pepper by 13–19%. Nevertheless, the mechanisms of enhanced flavonoid metabolism by Fe-based NMs and the subsequent induced symbiotic nodulation are still unclear.…”

Fe-Based Nanomaterial-Induced Root Nodulation Is Modulated by Flavonoids to Improve Soybean (Glycine max) Growth and Quality

Innovative technology to increase efficient nitrogen (N) use while avoiding environmental damages is needed because of the increasing food demand of the rapidly growing global population. Soybean (Glycine max) has evolved a complex symbiosis with N-fixing bacteria that forms nodules to fix N. Herein, foliar application of 10 mg L −1 Fe 7 (PO 4 ) 6 and Fe 3 O 4 nanomaterials (NMs) (Fe-based NMs) promoted soybean growth and root nodulation, thus improving the yield and quality over that of the unexposed control, EDTA-control, and 1 and 5 mg L −1 NMs. Mechanistically, flavonoids, key signaling molecules at the initial signaling steps in nodulation, were increased by more than 20% upon exposure to 10 mg L −1 Fe-based NMs, due to enhanced key enzyme (phenylalanine ammonia-lyase, PAL) activity and up-regulation of flavonoid biosynthetic genes (GmPAL, GmC4H, Gm4CL, and GmCHS). Accumulated flavonoids were secreted to the rhizosphere, recruiting rhizobia for colonization. Fe 7 (PO 4 ) 6 NMs increased Allorhizobium by 87.3%, and Fe 3 O 4 NMs increased Allorhizobium and Mesorhizobium by 142.2% and 34.9%, leading to increased root nodules by 50.0% and 35.4% over the unexposed control, respectively. Leghemoglobin content was also noticeably improved by 8.2−46.5% upon Fe-based NMs. The higher levels of nodule number and leghemoglobin content resulted in enhanced N content by 15.5−181.2% during the whole growth period. Finally, the yield (pod number and grain biomass) and quality (flavonoids, soluble protein, and elemental nutrients) were significantly increased more than 14% by Fe-based NMs. Our study provides an effective nanoenabled strategy for inducing root nodules to increase N use efficiency, and then both yield and quality of soybean.

“…These metabolites play a role as phytoalexins, phytoanticides and phytoncides (defense systems against many biotic stresses), antioxidants (control ROS), chelators (scavenging free metal ions), UV protectants, growth regulators, and factors against abiotic stresses (Feng et al 2021b;Nobahar et al 2021). Various NPs including iron (Fe), cerium (Ce), and SiO 2 , altered secondary metabolite content in lettuce and pepper seedlings (Kalisz et al 2021).…”

“…A number of studies reported the effects of NPs on plant secondary metabolism (Table 6.2). Accumulation of shikimate and phenylpropanoid pathway products was observed in cucumber and maize after foliar application of Cu(OH) 2 (Zhao et al 2018a) in wheat exposed to Ag (Feng et al 2021a), in pepper exposed to SiO 2 or Fe 2 O 3 (Kalisz et al 2021) and in A.thaliana exposed to CuO (Chavez Soria et al 2019) NPs. On the other hand, the amount of phenylpropanoids in lettuce, spinach, cucumber, and barley were decreased by Cu(OH) 2 (Zhao et al 2016b(Zhao et al , 2017b, CeO 2 (Zhang et al 2019b), soil application of CuO (Huang et al 2019), and CdO (Večeřová et al 2016).…”

Nanomaterial Interactions With Plant Cellular Mechanisms and Macromolecules and Agricultural Implications

View full text Add to dashboard Cite

Plants encounter various nanomaterials (NMs) as pesticides and fertilizers. It is also possible that nanomaterials reach plants as waste from consumer products and industry. The effects of such NMs on plants have been widely studied, and both positive and negative effects of NMs on plant growth and development have been reported. Recent metabolomics studies suggest that nanoparticles affect the concentration of secondary metabolites in plants by modulating reactive nitrogen/oxygen species, gene expression, and signaling pathways. Secondary metabolites are plant compounds that accumulate in plants through their secondary metabolism. To date, more than 200,000 defined structures of secondary metabolites have been identified, among which many of them possess antibacterial, antifungal, antiviral, anti-inflammatory, hepatoprotective, antidepressant, antioxidant, neuroprotective, and anticancer properties. The application of elicitors is a simple strategy to increase the production of secondary metabolites in plant cell and tissues. The ability of nanomaterials to induce plant secondary metabolism has recently been exploited in the elicitation of pharmaceutically important compounds from various plant species. The ability of different NMs to induce the accumulation of different classes of compounds in the same plant species has also been accomplished. The molecular mechanisms behind the effects of NMs on plant secondary metabolism revealed the putative genes involved in NM-mediated elicitation of various plant compounds in several reports. This chapter reviews the current understanding of the effects of nanoparticles on plant secondary metabolism and the elicitation of pharmacologically important compounds from plant species.

“…Furthermore, lettuce (Lactuca sativa), one of the most widely grown leafy vegetables, which is consumed fresh as salad, can be an optimal target for Fe biofortification [7]. Lettuce is not only a good source of minerals (potassium, magnesium, and calcium), vitamins (A, C, and E), and dietary antioxidants but is also known for its organoleptic properties [8]. The biofortification of lettuce with Fe would not only increase its nutritional and functional quality but would also provide an urgent and easy way to alleviate human Fe deficiency.…”

Foliar Application of Humic Acid with Fe Supplement Improved Rice, Soybean, and Lettuce Iron Fortification

Iron (Fe) deficiency in humans, particularly in pregnant women and children, is caused by inadequate dietary Fe intake and is a global nutritional problem. Foliar fertilization is a cost-effective agronomic approach to increase Fe bioavailability in the human diet. We evaluated the effects of different Fe formulations (Fe-citrate, Fe-EDTA, FePO4, nano-Fe oxide, and humic acid (HA) with and without Fe) on growth, yield, and Fe accumulation in the edible parts of rice, soybean, and lettuce crops. Rice and soybean received multiple sprays at different growth stages, i.e., tillering, anthesis, and grain filling in rice as well as flowering and pod filling in soybean, while lettuce received a single foliar spray. In rice and soybean, the seed Fe accumulation increased proportionally as the number of foliar sprays increased; however, the grain yield did not show this relationship. Among Fe treatments, HA+Fe was identified as the best treatment in terms of improving overall plant growth, yield, and Fe accumulation in the edible parts of all three crops. We found a significant positive correlation between the shoot/stover Fe content and the grain Fe content, but HA+Fe showed an opposite trend, i.e., minimal Fe retention in shoots/stovers and maximal increases in the seed Fe contents in both crops, suggesting better Fe mobilization efficiency from shoots to developing seeds. We strongly recommend that HA with Fe can be used as a foliar Fe fertilizer to improve the growth, yield, and Fe status in different crops.
