Marine endophytic fungi mediated Silver nanoparticles and their application in plant growth promotion in Vigna radiata L.
Authors
Abstract:
Seaweeds tend to have the property of acting as a biofertilizer for plants. Endophytes are organisms that are capable of mimicking and producing secondary metabolites similar to the host. In this report, silver nanoparticles (AgNPs) were synthesized from a marine endophytic fungus, Fusarium equiseti which was isolated from marine seaweed and identified using ITS sequencing. The synthesized Fusarium equiseti nanoparticle (FeNp) was characterized using UV Visible Spectrophotometer and field emission scanning electron microscope (FESEM). Efficacies of these nanoparticles to act as plant growth promoters were tested in laboratory conditions. Two different methods of administrations are nanopriming (NAP) and hydropriming (HYP), which were carried out with varying concentration of the FeNp (1ppm, 2.5ppm, 5ppm and 10 ppm). After comparing both the results, HYP method showed better results by favouring positive effects on wet weight, shoot length, root length, chlorophyll and carotenoid contents even at very low concentration (5ppm).The current results suggested that there is scope for these nanoparticles to be made into a biofertilizer after performing further toxicity studies under field conditions.

Influence of Nanoparticles on Seed Germination and Seedling Growth of Vigna radiata L
We describe a simple and cost effective method for screening the effects, of stem extract along with biogenic nanoparticles synthesized from Cissus quadrangularis stem extract, on Vigna radiata seed germination and root length. At higher concentrations (200 μl to 300 μl) of stem extract (1 2.5 g ml ) germination was completely inhibited. The inhibition was dose dependent. Synthesized nanopartic...

Eucalyptus cultivation has expanded considerably in Brazilian systems, leading to the current search for technologies to optimize growing conditions and the production of seedlings in nurseries. Based on the understanding that the development of tree species such as Eucalyptus sp. can be influenced by endophytic fungi that act directly as plant growth-promoting species, cloned seedlings of Euca...
