Abstract:
Among various biotic agents infecting plants, viruses have significant impact particularly members of Gammaridae (Begomoviruses) carried by insect vectors causing economic losses in agriculture ornamental and medicinal plants. Cestrum nocturnum L. (Night blooming jasmine) which is a common medicinal plant was also found exhibiting begomoviruses infection symptoms. The purpose of the present work was to compare the begomoviruses infected and non-infected plants of C. nocturnum via multiple analyses. Various surveys were conducted to observe the disease incidence in different regions which indicated the prevalence of begomoviruses. The comparative morphological and anatomical analyses were performed for both samples. Antioxidant analysis was performed using different extracts prepared in methanol, ethanol, n- hexane and chloroform by observing absorbance at 517 nm with the help of spectrophotometer following DPPH (Diphenyl-1-picrylhydrazyl) assay. Strong antioxidant potential was exhibited by samples. Phytochemicals analysis revealed the presence of terpenoids, tannins and flavonoids while phlobatannins was absent in both infected and non-infected plant. Antimicrobial activities of collected samples were performed by well diffusion method against Staphylococcus aureus, Klebsiella pneumonia and Escherichia coli, Rhizopus stolonifer, Aspergillus nigerand Alternaria solani. Infected and non-infected plant possessed antibacterial potential but antifungal activity was not found. It is concluded from the current study that begomoviruses infection is responsible forreducing antioxidant and antimicrobial potential of C. nocturnum while decent level of phytochemicals constituents were observed in infected plant which may be due to viral infection. C. nocturnum is a cosmopolitan and attractive plant such sort of diseases can be a big thread to such a significant plant.
