Inhibition of Fusarium solani in transgenic insect-resistant cotton plants treated with silver nanoparticles from Prosopis glandulosa and Pluchea sericea

Abstract

The phytosynthesis of nanoparticles is a green chemistry approach that combines nanotechnology and bioactive compounds of plants. The aim of this study was to evaluate the effect of silver nanoparticles (AgNPs) from Prosopis glandulosa and Pluchea sericea, respectively, on the control of Fusarium solani previously inoculated in the rhizosphere of transgenic insect-resistant cotton plants. The results showed that the weekly application of AgNPs from P. glandulosa and P. sericea caused a diminution of fungal propagules in the soil after 30 days of treatment. In this sense, the AgNPs from P. glandulosa were more efficient in the reduction of infection points in the roots of the plants infected with F. solani compared with AgNPs from P. sericea. Additionally, the application of AgNPs from both plants showed a significant increase of optimum quantum yield (Fv/Fm), stomata conductance (g s ), and the number of lateral roots in transgenic insect-resistant cotton plants after 30 days of exposure when compared to the control. Based on our results, AgNPs from P. glandulosa and P. sericea could inhibit growth of Fusarium solani. However, more extensive and elaborate studies are needed to explain the different mechanisms that participate in the inhibition of growth of fungus using nanoparticles from these plants.

Biocontrol potential of mycogenic copper oxide nanoparticles against Alternaria brassicae

“…Nanoscience leads to the development of low-cost, environmentally friendly nanomaterials, which initiates the disease resistance power of crops exposed to nano-products ( Patra and Baek. 2014 ; Abdelmoteleb et al, 2018 ). Previous literature studies have reported the various fungal species, Fusarium , Verticillium , Alternaria , Penicillium, and Trichoderma , employed for nanoparticle synthesis ( Hassan et al, 2019 ; Mohamed et al, 2020 ; Badawy et al, 2021 ; Shaheen et al, 2021b ).…”

The Potential of Piperidine Alkaloids-rich Extracts from Prosopis spp. to Combat Plant Pests and Diseases

“…The polar extracts (ethanolic and aqueous) of the leaves have displayed antifungal activity and the alkaloid rich fraction derived of the extracts recorded higher activity [21,22,50]. Besides, the aqueous extract has been used to generate silver nanoparticles with antibacterial and antifungal activity [51,52].…”

“…extracts or chemical constituents to the control of phytopathogenic fungi could be potentiated through the formulation of nanoparticles. Silver nanoparticles (AgNPs) obtained from aqueous leaf extract of P. glandulosa inhibited the in vitro and in vivo growth of F. solani in cotton plants [52], and zinc oxide nanoparticles (ZnONPs) synthesized with aqueous extract from P. farcta pods exhibited antifungal activity against 10 clinical isolates of C. albicans [87].…”

Biogenic Synthesis and Characterization of Silver Nanoparticles: Evaluation of Their Larvicidal, Antibacterial, and Cytotoxic Activities

“…Medicinal plants generally have biosurfactant molecules such as alkaloids, saponins, tannins, glycosides, flavonoids, and phenols. Thus, the materials prepared by the green synthesis method are a potential candidate for larvicidal activity and reducing the accumulation of toxic residues in the aquatic organisms. , …”
