    • Abstract

       

      Eco-friendly biosynthetic approach for silver nanoparticles production using plant extracts is an exciting advancement inbio-nanotechnology and has been successfully attempted in nearly 41 plant species. However, an established model plantsystem for systematically unraveling the biochemical components required for silver nanoparticles production is lacking.Here we used Arabidopsis thaliana as the model plant for silver nanoparticles biosynthesis in vitro. Employing biochemical,spectroscopic methods, selected mutants and over-expressor plants of Arabidopsis involved in pleotropicfunctions and sugar homeostasis, we show that carbohydrates, polyphenolics and glyco-proteins are essential componentswhich stimulated silver nanoparticles synthesis. Using molecular genetics as a tool, our data enforces the requirement ofsugar conjugated proteins as essentials for AgNPs synthesis over protein alone. Additionally, a comparative analysis ofAgNPs synthesis using the aqueous extracts of some of the plant species found in a brackish water ecosystem (Gracilaria,Potamogeton, Enteromorpha and Scendesmus) were explored. Plant extract of Potamogeton showed the highest potentialof nanoparticles production comparable to that of Arabidopsis among the species tested. Silver nanoparticles production inthe model plant Arabidopsis not only opens up a possibility of using molecular genetics tool to understand the biochemicalpathways and components in detail for its synthesis.
