Bioengineered chitosan-iron nanocomposite controls bacterial leaf blight disease by modulating plant defense response and nutritional status of rice (Oryza sativa L.)

Bio‐Functionalized Manganese Nanoparticles Suppress Fusarium Wilt in Watermelon (Citrullus lanatus L.) by Infection Disruption, Host Defense Response Potentiation, and Soil Microbial Community Modulation

“…[33] For example, different hydrolytic/ metallo-enzymes, such as galactosidase, catalase, and peroxidase, present in the bacterial culture filtrate have been reported to be involved in the biosynthesis and stabilization of silver, magnesium, and iron NPs. [17,33,34] Overall, these findings are consistent with previous observations that MnNPs can be synthesized by culture filtrates of Paenibacillus polymyxa DEBB B-358, isolated from Eucalyptus leaves, or a metal-resistant Bacillus sp., isolated from soil. [35,36] It has been previously shown that different biomolecules present around the surface of NPs also contribute to the stability of biogenic metallic NPs.…”

“…The tremendous direct antifungal activity of bio-MnNPs than bulk Mn(II) might be due to various biomolecules including lytic enzymes covering their surface. [34,48] These in vitro sensitivity assays are unique, as the antimicrobial activity of bio-MnNPs against phytopathogens is unknown. Bio-MnNPs are known to have antimicrobial activity against human pathogenic bacteria, such as Staphylococcus aureus and Escherichia coli.…”

Effects of Different Microbial Fertilizers on Growth and Rhizosphere Soil Properties of Corn in Newly Reclaimed Land

“…The analysis of beta diversity was carried out to observe the structural variation of the rhizosphere soil microbiome across samples with principal coordinate analysis (PCA) [ 21 ]. The difference in the rhizosphere soil microbiota between groups was determined by analysis of the similarities, and the linear discriminant analysis effect size (LEfSe) was carried out using default parameters to observe the differentially abundant taxa between groups [ 22 ]. To investigate the impact of environmental factors (such as pH, total N, available P, etc.)…”

Nanobiopesticides in sustainable agriculture: developments, challenges, and perspectives

“…18,19 The main categories of nanomaterials are pure carbon nanostructures, inorganic nanomaterials, organic nanomaterials, and organic-inorganic hybrids according to their composition, 20 and the most widely used NPs in agriculture are silver, copper, titanium, zinc, silica, gold, aluminum, iron, chitin NPs, chitosan, nanoclay, graphene NPs, multiwalled carbon nanotubes, and biopolymers. [21][22][23][24][25][26][27][28] Nanobiopesticides are associated with optimistic innovative technologies of producing and utilizing biopesticides that fall in the nanoscale (1-100 nm). 29 However, the nanocarriers used for medical, cosmetic, food, or agricultural applications generally have outer diameters much larger than 100 nm, although the internal functional features may be smaller than 100 nm.…”
