AI Article Synopsis

  • The study explores a green alternative for controlling plant diseases using myco-synthesized silver nanoparticles (Ag NPs) to minimize synthetic chemical usage.
  • Ag NPs were successfully synthesized from a substance found in corn grain contaminants and characterized using various scientific techniques to confirm their properties.
  • The effectiveness of these Ag NPs was tested against specific pathogens that affect cotton seedlings, showing significant antifungal activity and reduced fungal growth at varying concentrations.

Article Abstract

In this investigation, an alternate green-route based on myco-synthesised silver nanoparticles (Ag NPs) was evaluated to control plant disease to reduce the usage of synthetic chemicals. Here, we described biologically synthesised Ag NPs using the corn grain contaminant, , and were well-characterised by UV-visible spectrophotometer, X-ray powder diffraction (XRD), transmission electron microscopy (TEM), Energy Dispersive Spectroscopy (EDS) and particle size analyzer. The pathogenic behaviour of the spp. were checked on Giza 86 and Giza 90 cultivars under greenhouse conditions. and exhibited high pathogenecity against Giza 90 and Giza 86 cultivars respectively. The antifungal activity of biosynthesised Ag NPs was evaluated against eight species of causing damping-off of cotton seedlings. treatments with different concentrations of Ag NPs were achieved on Czapek Dox agar and Potato dextrose agar plates. Fungal growth was drastically retarded from 25 to 200 ppm of Ag NPs interaction. The antifungal activity of Ag NPs against the spp. was clearly proven.

Cold atmospheric plasma (CAP) has emerged as a promising technology for neutralizing microbes, including multidrug-resistant strains. This study investigates CAP's potential as an alternative to traditional antimicrobial drugs for microbial inactivation. In the era of increasing antimicrobial resistance, there is a persistent need for alternative antimicrobial strategies.

An unusual clathrate-type meroterpenoid isoatlantinone A (1), two new steroids acrocalysterols E (2) and F (3), together with fifteen known compounds (4-18) were separated from a plant-associated fungus Penicillium fellutanum. Their structures and absolute configurations were established based on spectroscopic data (NMR and HRESIMS), electronic circular dichroism (ECD) and modified Mosher's method. Notably, compound 1 represents an unusual highly oxygenated meroterpenoid derivative with a unique caged bioxatetracyclo-[6.

Increased virulence and drug resistance in species of resulted in reduced disease control and further demand the development of potent antifungal drugs. The repurposing of non-antifungal drugs and combination therapy has become an attractive alternative to counter the emerging drug resistance and toxicity of existing antifungal drugs against and non-albicans species. This study aimed to accelerate antifungal drug development process by drug repurposing approach.
